  3. I honestly hope that people from Panasonic are reading this.

    I would gladly pay another 99$ for internal 4K 200Mbit IPB 4:2:2 8bit recording!

    Together with V-log this combination would be sufficient for 99% of work.

    Cheers!

  4. That's funny, the same shop... they do have good prices indeed.

    Now I get it, the tripod needs to fit the Airlines hand luggage, and Ryan Air and other budget Airlines have tough restrictions for their hand luggage. But I don't think they would allow it on board, it can be used to threaten someone and that's a no go. It's best to check with them, call them or send them an e-mail. Maybe just maybe a light carbon fibre tripod could be allowed, with no spikes on the tripods legs feet, just rubber. But honestly I would not even think about putting it in a carry on luggage. Perhaps others can share their experience?

    As for Triopo, cannot say anything about quality of other triopo tripods, but I have recently bought Triopo MX-1327 ( http://foto-tip.pl/en/statyw-triopo-mx-1351.html ) and for that price it's unmatched by any other tripod, big and strong, but still not too big. Fully extended it does twist using the 502 head with big drag and a 2.8kg rig on top, but when you calculate the height of the ball adapter and the height of the 502 head, it doesn't need to bee fully extended to rech the eye level (I am 179cm). I've compared it with Manfrotto 055XProb and it feels the same in terms of stabillity.

    If I were you I simply wouldn't bother with a tripod that fits in the carry on luggage.

    As for the level head,don't know how manfrotto performs, it's more then double the weight and has much less adjustment then sunwayfoto dhy-66i (+5/-5 VS +16/-16 degrees). Also from the looks of it, it doesn't look that it's very easy to adjust...If you really want manfrotto have a look at Manfrotto 436, but it's even bigger and heavier. My sunwayphoto dhy-66i will arrive next monday, and I will test it on Triopo MX-1327 with Manfotto 502 head and a 2.5-3.5kg rig on top. I will share my experience then!

    I do have to warn you again about reversed controls on the 502 head, if you are familiar with standard position of locking knobs on a video head, the 502 can give you headaches. I do not mind it, but it's something to think about.

    Happy choosing :)

     


  5. Hi!

    I just have a few pointers that maybe will make your decision a little easier.

    Concerning the heads:

    Big difference between Manfrotto 500 and 502 Heads is Pan and Tilt variable drag control that 502 has which makes a huge difference when you need both slow and fast movements. The 500 has fixed Tlt and Pan drag, you have to try it if it works for you. It could be to loose for your gh4 and lens combination. I recommend to go somewhere and try it first. The 502 on the other hand can be adjusted to be completely loose or very stiff but still fluid. The 502 is much bigger and heavier and has controls on the oposite side, which many people hate, maybe you will hate it too, because of that I also recommend to try it first.

    But in your case, I presume that you will be using a tele lens, so with that in mind I would reccomend the 502 because a small movement on the head is a big movement in the video on the tele end.

    Concerning the tripod:

    What you want is a small light tripod that extends a lot, and that's a problem becasue that kind of tripod needs to have a lot of stages (leg extensions) and with every additional leg extension adds to overall instability of the tripod. Also, having a lot of leg extensions is a real hassle, I mean real pain in the ars especially if you have to move quickly to another location and can't move with extended tripod.

    Another thing, concerning the tripod (foto tripod legs) with many stages and a video head like 502 with Pan drag adjusted to be stiff, there will be a big problem regarding the tripod's Torsional Rigidity ( just google "Tripod Torsional Rigidity" ). When you pan the head in one side, the legs will twist in that direction and when you stop the movement and let go of the handle, the legs will twist again to return to their normal state and you will have a big backlash in your video. Just something you have to bear in mind. I have seen several times people blaiming video heads for the backlash, but actually the legs were to blame. Professional video tripod with a center or a floor spreader minimises that backlash.

    Also if you are going to buy that small photo tripod to mount a video head on it, I recommend adding a ball adapter (half bowl) because adjusting for the horizon with the legs only is a huge hassle and time consuming. There are several on the market, cheaper ones like sunwayfoto dhy-66i (new revision) are quite good. ( http://foto-tip.pl/en/sunwayfoto-dyh-66i-leveling-base.html )

    A light, small, good quality and afordable price tripod is very hard to find, though I have recently bought a Triopo foto legs tripod for 85€ and quality is very good so try to see if something from their range suite you like: Triopo GE-3232X8C ( http://foto-tip.pl/en/statyw-triopo-ge-3232x8c.html ) this is just an example, you can browse to see what other tripods they have, and maybe in your case, depends where you are from, you can probably find them cheaper somewhere else. Triopo is ok for the price, 24 months waranty in the EU and many web shops have it.

    I would also recommend max 3 stages for a video tripod legs, but you need it to bee quite small when not in use and quite long when extended, and that complicates things.

    Hope this helps a bit.

    Cheers

  7. Aaaaah to bad :(

    I'm not happy, because I have just made up my mind to shell out 400€ for MustHD 7" thinking that it's actually usable outside with it's sunshade.

    Didn't want to go really cheap on the monitor, so thought that MustHD 7" should be pretty decent for that price, and usable outdoor, I expected nothing special just to see what I am doing and to see the peaking.

    But, what about using something like this on the mustHD 7" monitor? This is just an example, just to see what I am aiming at:

    http://hoodmanusa.com/cgi/commerce.cgi?preadd=action&key=HRSAL

    There are various models all over the internet for various sizes of monitors, you just need o find the right one.

     

  8. Well looking at the Dxomark results, at 19mm Sigma is T1.9.

    Leica 19mm f2.8 could very well be T2.7 or even lower, I do not know that as a fact, just guessing. So the difference shrinks very quickly.

    Just a thought, do you have metabone adapter with aperture control? If yes, have you simply tried switching adapters just to see if the adapter is not messing with the aperture pin on the Sigma.

    Also I would try to photograph or make a video of a something much darker, like a candle on a table with it's surroundings. The difference should be much more obvious then.

  9. I'm looking to use the Nikon version of the Sigma 18-35 on a Canon mount camera. Anyone tried that? What were your experiences? Is it too big of a hassle? Any experiences with the following or similar adapters?

    http://www.bhphotovideo.com/c/product/724050-REG/Novoflex_EOSNIK_NT_EOS_NIK_NT_Lens_Adapter_for.html

    http://www.bhphotovideo.com/bnh/controller/home?O=&sku=995261&gclid=Cj0KEQjw6tepBRDLqLnxouaY_pkBEiQAPIOiBuQPPviNGidWVabw6sQUZQVUOaDVKZSxmBCsgREas48aAj_m8P8HAQ&Q=&is=REG&A=details

    ​These adapters should work, and they both control the aperture of the Nikon G type lenses.

    You cannot go wrong with Novoflex, made in Germany with very high precision, very high quality materials.

    Fotodiox should be ok, if you can buy it and try it with the option of returning it then why not.

    But my experience with various low cost adapers is not so good, the problem is with the lenses not reaching infinity or going past infinity, they are usualy too thick or too thin (fraction of a milimeter counts here) and in my experience wide focal lenght lenses require even more high quality precise adapters.

  10. If you want the one of the best then Heliopan Vario-Graufilter.

    Heliopan Vario-Graufilter type 2099 is thicker with front filter thread and type 2199 is a slim type and thinner without front filter threads.

     

    In Europe Helopan 2099 Vario-Graufilter 77mm costs about 200€.

     

    Me and my partner are looking to buy a permanent solution for our ND's, and we've done a lot of research on the internet which one to buy. It allways comes down to heliopan.

     

    You do not wan't to go cheap on these filters, trust me :)

     

    Cheers!

  11. Hi!

     

    I have BMCC speedbooter on GH4 and have also found the same problem, but there is a solution, quite simple one :)

     

    Just turn ON "Silent Mode" in the menu (wrench and C letter icon menu subsection) and now you can use custom white balance without engaging mechanical shutter. It will only use electronic shutter.

     

    By turning on "Silent Mode" , GH4 will not reproduce any sound (shutter included), zero, none, it's dead silent. It will record sound normaly but It won't even reproduce sound when playing back recorded videos, unless you are using headphones! :)

     

    Hope this helps.

     

    Cheers!

  12. I cannot find the article unfortunately, it was many moths ago that I've read it and I remember it vaguely...maybe I do not recall it 100% corectly

     

    What I have found is this article on Imaging Resource:

     

    http://www.imaging-resource.com/news/2014/06/05/panasonic-executive-interview-part-i-why-no-long-teles-and-depth-from-defoc

     

    Just scrool down to the second half of the page where it says "Downsides of on-chp phase-detect, especially for 4K video"

     

    They talk about similar thing, compensating for phase detect pixels, perhaps it can be done but requires a lot of processing power and can very likely introduce artifacts.

     

    Maybe Olympus can do it, while Panasonic decided not to use it because of the problems that go with it and especially togeather with 4K video.

  13. I honestly doubt that olympus will add 4K video with the firmware option, why? Here is an explanation that I find plausible.

     

    Olympus E-M1 has on sensor AF phase-detect and I recall reading an interview with the panasonic top engineering team who designed GH4, and they said that among other reasons why it was not implemented in GH4,  on sensor AF phase-detect is not compatible with the sensor readout required for the 4K video capture.

    Basicaly they said that the AF fase-detect part of the chip requires slower/different readout, and since it ocupies a lot of pixels on the chip, that part of the sensor cannot be read as fast ( or in the same manner) as all of the rest.

     

    Maybe it can be done with lots of line skipping, where you can avoid those parts of the sensor occupied with AF fase-detect pixels. I see no problem using this method for 1080p video where you have a lot of data to reconstruct the final video, but 4K video on 16MP sensor leaves very little room for that, if any, also you can forget full sensor readout that both GH4 and A7s have.

     

    So unless Olympus created on sensor fase-detect pixels that others cannot, I don't see a way to implement 4K video without some trickering in form of line skipping and maybe upscaling.

     

    I'm not an expert so I could be very wrong, and this is only my opinion on the matter.

     

    Cheers to everybody!

  14. I don't understand spending $1700 on a cam to do 4k work and then thinking of the lens as some kind of afterthought. Buy a quality lens if you want to do serious work.

     

    Simply priorites, wide angle is not something I need very often and do not want to invest serious money into it (and I can't at this moment), but would like to have it for some shots. So I wanted to see if there are good enough options (not great, not excellent) that fit within my budget.

     

    I have everything covered from 40mm to 160mm, with good quality glass, this is the range I use the most.

     

    I believe there are also others like me that seek low cost options...not everybody can afford the luxury of buying only high quality expensive lenses...we all have priorities.

  15. Thanks for the answers!

     

    I was kinda hoping that somebody has experience with the lenses mentioned in the first post. I can see from the recommendations and also from the web that 14mm f2.5 is quite good and a viable choice...not quite wide but with my budget it's ok. Putting a wideangle adapter on this lens is a nice thought and they came quite cheap, but I don't expect great results.

     

    Tamron 17mm f3.5 with adaptall2 to nikon is around 160€-200€ , a will look into it!

    It gives me around 11mm f2.2 with the BMCC speedbooster, which is very very nice...thing that bothers me is that protruding front lens element. It could interfere with the ND.

     

    Zuiko 12mm f2 is a great little lens, and I know it's qualities but way over my budget like nikon 10-24.

     

    Again regarding Fujinon 12.5mm , edges of the frame are way to soft, but yes 4K does give you a crop but stil...how does it behave at 2.8 with the 4K  crop, that I do not know...it seems to me that it is to much work and hassle over modification for something questionable.

    If someone has a video sample of a Fujinon 12.5mm f1.4 at f2 and f2.8 in 4K I would very much like to see it.

     

    I'm looking for something within my budget that has decent sharpness and quality, also at least f2.8 usable aprture for indoor recording (calculated with the speedbooster where applicable),  used lenses are welcome...only Panasonic 14mm f2.5 I can find new at a low price.

     

    We shall see :)

  16. Ive modified all my fujinon c mount lenses my self its easy to do .....if you have a lathe!

     

    Hehe I know, I bought the little Fujinon TV 25mm 1.4 from you, you told me that you've modified it yourself. Still have it, it's a great little lens.

    But I don't have the skils nor the lathe and don't know anyone that can help me with that. But even if I did, Fujinon 12.5mm f1.4 doesn't convince me from the acceptable sharpness standpoint.

  17. Thanks everybody for answers!

     

    Yes 14mm is not really wide considering 4K crop, but it's a viable choice considering my budget, while 17mm 2.8 is definitely not what I'm looking for..

     

    Sigma 10-20 would be nice on a speedbooster but too expensive even used.

     

    Tokina 11-18 f2.8 is the lens I was looking at, it would be perfect but it's expensive, a used one is also expensive, goes around 350-400€.

     

    Regarding the Fujinon 12.5mm f1.4 from the video above, it has charm and character but too soft on the borders, maybe it gets better at f2.8 , I was interested in that lens some time ago for other reasons and also contacted the person that modifies it to work properly on m43 bodies, but he told me that he doesn't do it anymore.

     

    With all this talk, I'm starting to convince myself that sigma 18-50 2.8 is not a bad option :) 11.52-32mm f1.8 with the BMCC speedbooster.

    But numbers are one thing and how will the sigma behave on the speedbooster is another thing.

     

    Still hunting :)

  18. Thanks for the answer.

     

    Wide angle is to be used purely for video, 4K recording, which has 2.2x crop, in all situations.

    I don't care about AF or electronic aperture control, everything I do is on full manual.

     

    14-54 is a highly regarded lens and on 14mm it gives me 30.8mm wideangle in FF terms at f2.8

     

    14mm is a great little panckake lens which also gives me 30.8mm wideangle in FF terms but at f2.5.

     

    I do not mind the size of the two above, just which gives me better quality video with less distortions and cromatic aberations.

     

    While sigma 18-50 2.8 on BMCC speedbooster gives me about 25mm in FF terms at f1.8.

    Sigma is very tempting for low light and wider angle, but I cannot tell how does it compare optically with the two above.

     

    I allready have BMCC speedbooster and it's great with nikon mount glass (samyang 35mmm 1.4 and tokina 28-70 2.6-2.8), while my friend has the normal one for m43 (0.71x). Difference in sharpness between the two I cannot tell, but difference in light gathering is clearly visible. It's more then 1/3 of a stop, to me it seems like 1/2 of a stop.

     

    I'm still hunting :)

  19. Hello to everyone!

     

    I would like to buy some decent moderate wideangle for GH4 but have limited budget unfortunately.

     

    I came down to these 3 options:

     

    1. Used Zuiko 14-54 f2.8-3.4 MK1 4/3 mount + electronic adapter (MMF-1 or MMF-2) - 190€

     

    2. New Panasonic 14mm f2.5 - 180€

     

    3. Used Sigma 18-50 f2.8 EX DC Macro Nikon mount - 160€

     

    wideangle needs to be useful for both outdoor and indoor shooting.

     

    Since I allready have BMCC nikon speedbooster (0.64x) to me the best option seems Sigma 18-50 f2.8 but I cannot find anywhere how sigma behaves, especially on 18mm with the speedbooster attached (11.52mm).

     

    There is also a used Tamron 17-50 f2.8 nikon mount for 250€, but I do not want to go that far with the price if I don't have to.

     

    Advices are really welcome :)

     

    Thank you all in advance!

  20. This is my first post, but longtime reader :)

     

    I've downloaded the file and imported it to Premiere Pro CC.

     

    Now when the file is imported in the 4K sequence or 1080p (downscaled from 4K) sequence it stutters and loses frames for smooth playback. (You can see that by enabling "Show Dropped Frame Indicator" in  the program monitor playback window top right corner. It is GREEN when there are no droppped frames and turns YELLOW when Premiere is dropping frames)

    When I play it at 1/2 resolution from the 1080p sequence (downscaling from 4K) it is buttery smooth and no dropped frames.

     

    What I did next is exported the 4K clip as 1080p clip at 20Mbps with maximum settings for downscaling for best results.

    Resulting clip plays smoothly in MPHC, PowerDVD13, VLCplayer and in Premiere Pro once re-imported.

     

    I have to say that prior to converting the clip from 4K to 1080p, it stuttered in every player I've tried.

     

    The very same thing happens with my GH4 clips, and I think it's a PC hardware/software problem with latest h.264 codec unfortunately.

     

    I've downloaded P. Blooms A7s 4K test recorded on Blackmagic Ultrastudio 4K and it is recorded at 345Mbps as Prores LT which plays without any dropped frames in Premiere Pro CC at full 4K resolution.

     

    My PC config is:

    Intel Core i7 3770 at 4.2Ghz

    32GB DDR3

    AMD HD7950 3GB

    6x HDD all WD black 7200rpm from 1TB to 4TB

    Win7 64bit

     

    So pretty good configuration with full support of GPU hardware acceleration in Premiere.

     

    Hope this helps a bit.
