so, kinda back on topic. Would the issues on this video before a firmware update on the GX85? I am totally confused now.

fast forward to 4:30

//

and if so, would Panasonic do the same thing for G85? Or, is this just a stunt to sell more GH5?

Haha...might get my G80 after all...that looks to be the exact same issue on the GX85 (from 4:37 to be precise ;-))
Which they obviously fixed (???) as demonstrated in the G80 vs GX85 videos...

Congrats on selling this one!

Holy crap a 1000 pounds! Congrats indeed.

It aint cheap, but it is a price that you see more often. If you wait, you should be able to get one like this for cheaper though. Negotiating is also an option of course ;-)

If you find a Kowa 16H or 8Z for this kind of money it is a better deal.

Damn, I was planning to get this too...Have good hopes this is fixable, but I want to see it happen before I spend the cash.

This looks more like a rebranded 16D or 16C, like Sankor made but they also came branded differently. Ask the seller if there are any numbers on the lens body. It will help identify the model.

The one you show looks to be smaller than Kowa B&H / 16H / 8Z (which share the same build and size). Those are popular because of high quality glass and large lens elements that allow for somewhat wider taking lenses.

Having said that, if the lens you found is in good shape and well priced, it can be a good start for shooting anamorphic.

Eh...it's in this thread, right!?

(sold, but you can check how it looks)

Yeah, there is a certain overlap in what you can achieve with different sized sensors. As shown, this goes for composition, but to an extent also for technical picture quality. Example: with a 25mm f1.4 on MFT you get the same FOV/DOF as a 50mm f2.8 on fullframe, but you also (partially) negate the smaller, noisier sensor because you have a faster lens.

But there are limits as to what is practically possible. There is no MFT equivalent lens for the famous 50mm f1.0 on fullframe. On the other hand, you won't find a compact drone with a fullframe sensor (for now, ha!).

I don't think anyone was arguing the math... These CGIs are useless, they show us nothing of sensor difference only equivalence of focal length and aperture, which as far as I can tell everyone had agreed on.

I'm pretty sure Mattias didn't agree with what @bunk proves ;-)

What kind of sensor differences do you mean exactly? Noise, bit depth, resolution etcetera? Sure there can be differences in technical picture quality, but as shown above: framing and DOF can be made identical while shooting from the same spot with different sensor sizes...by using equivalent lenses.

Seriously anybody tried the new 40 ? any reviews?  i might just buy one and return if not up to par

And, did you buy one? Seriously zero reviews online, and I'm also curious about this thing

Ah, what a shame...the video test is well done and clearly shows the issue. As the author from the video states in the comments, it looks like a 'tuning' problem on the IS...something that hopefully/probably? is fixable with a firmware update.

@Hanriverprod sorry to hear your bad experience man, I had a 14-140 in the kit with my G7...toyish build and you could hear moving parts around when slightly shaking it. It did work fine though, so I attributed it to the plastic build. Great travel lens, but sold it because of the slow aperture and because I mainly use vintage glass for video. Hope your refund or switch for another model works out.

A 50mm f1.8 on a s16 has the exact same dof as it does on a FF from the same distance.

(...)

Its simple physics.

Dude, please stop dancing around. We (you included) were talking about recreating the same picture (dof and framing) from the same spot using different sensors.

Also a fan of your YT reviews, but I'm having a hard time figuring out whether you're trolling us here.

But yeah, let's let it go...there's enough in this thread for everyone to make up their minds.

Yeah, this discussion... opinions on facts :-/

For those interested, the Northrup video comes recommended. He explains and proves his point.

For readers, Dpreview did an extensive piece on it as well, with 2250 comments full of confusion :-)

No you cant. Look at the Tony Northup frame I posted. It clearly proves that you can replicate the image from a large sensor in the way you earlier suggested.

I tell you what. Take the three lenses and sensor sizes you listed in your first post. Take three photos from the same distance of the same subject. A person with a background similar to the example I posted.

I will give you $100 it they turns out exactly the same. 

So if I understand you correctly, there is no way to recreate the exact same picture using two different sized sensors from the same position? Nah...sure you can.

Just give Northrup your 100 bucks :-) He made a few videos proving this point. The very example you posted is among the 'evidence' he presents, check the vid.

@Mattias Burling we seem to disagree, so let's explore this al little bit, because I think understanding equivalence is useful for anyone, especially when juggling camera's with different sized sensors.

• You didn't respond to what I said, i.e. you can get the same framing, same depth of field, shooting from the same spot...with different sensor-sized camera's. The key is using lenses that compensate for the differences in sensor size.
• The math concerns using crop factors for both focal length and f-stop to estimate the effects on framing and DOF. The physical f-stop obviously does not change.
• You show a screenshot from a Tony Northrup video that proves exactly these points! In the example using 100mm f5.6 on full frame yields the same framing and DOF as a 50mm f2.8 on MFT (2x crop).
• You can hear Northrup explain from 16:06...your example shows up right at 17:18 :-)
• Obviously there are limits as to what is currently possible. Getting the same framing and DOF as a fullframe 50mm F1.2 on a MFT camera would mean using a 25mm F0.6, which doesn't exist (yet!).

Holding cameras in the exact same position, you can take the same (framing, DOF) picture with:

• a 50mm f1.8 on full frame
• a 35mm f1.2 on APS-C
• a 25mm f0.9 on MFT

So there really is no specific aesthetic linked to a certain format, just math.

Go with the C100ii. 

But then we're talking $900 (G85) vs. $4000 (c100 ii)...

Sexy gadget...Fotodiox also makes one, looks a tad more rugged:

Here's hoping for a MFT version...and it's a matter of time before they put in a focal reducer as well

Out of curiosity: where did you find this? Or did you just happen to have it in your collection?

I think I read somewhere here or otherwise that the distance between the rear element of the anamorphic adapter and the entrance pupil is inversely correlated with the quality of the pairing.

So pancake lenses rule then?

Noob question I guess, but how exactly can you use this measurement? Cheers, Tim

Hi Folks,

I've put an item on Ebay after finding it in my collection of Cinefilm cameras, but I have to confess, i'm not totally sure what I've got or how I have so much interest so quickly. Can anyone confirm if i'm advertising it correctly? The last thing I would want to do it be wrong!

The link - http://www.ebay.co.uk/itm/332011952084?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Thanks

You got quite the rare lens there. It is highly sought after. Just google "baby hypergonar". Don't worry...codewords "anamorphic" and "cinemascope" are in the title; people who want to buy this will find your ad :-)

Hey everyone. Just some background on my setup. I've got an URSA Mini 4.6k (so slightly larger than APS-C image circle).

I'd like to get my first anamorphic. Preferably something that can sharply focus as close as 2 feet (or better) after adding a Rectilux CoreDNA to it. And handle a 50mm wide (or wider) taking lens.

Is this a good / possible option? http://www.ebay.com/itm/262666642926

Hey man. Check out Tito's FOV calculator; it lets you know whether a lens will (probably) vignette or not: http://www.tferradans.com/blog/?p=8615

• wider than 50mm on S35 is difficult with a 2x stretch; 1.5x or 1.33x will give you more options (but obviously less oval bokeh unless you use an oval aperture).
• the larger the anamorphot's elements, the wider you can go with your taking lens. Hence the popularity of Kowa B&H/8Z/16H/Elmoscope II (all the same build and size). The SLR Magic anamorphot 2x-50 might also get you wider than 50mm but it's expensive and flares blue like crazy.
• to get a feel for flare colours, try to look up video examples online. The Sankor 16C you mention is nice and sharp, but has mostly blue coatings and thus blue flares. Also, you can ask a seller to take a picture of the lens under an angle with light source overhead to get an idea of the colour of the coatings.
• the coreDNA will introduce extra vignetting; ask around in this thread for user's experience
• listed mininum focus distance for the coreDNA is 0.7m; if you need more you can add a diopter in the mix or set both taking lens and anamorphot to minimum focus distance

Some photos of current construction. Beautiful body for single focus in progress.

Will you let us know how you built it to be single focus? :-)

...This is the best thing in their current line-up (unless you're more geared towards photography, then the GX8 has some features that might make that one more interesting). Of course, the GH4 has its use and the GH5 is going one step further yet, if not an entire leap and both bring those video production qualities to the table. But the GH5 is going to be double the price and take another half a year... Don't get why hardly anybody seems excited about this one. Everybody seems to either drop specs for the ease of use of the Canon (dualpixel AF & color) or actually go for the more exciting specs (Sony) and 'just deal with it'.

Same here. The G7 was well regarded for budget-minded shooters. Look at what is improved: sensor stabilisation, weather sealing, clean HDMI out during internal recording, reportedly fixed shutter shock in photography and more. And all this for under 1K with great deals especially in UK. This camera deserves to be a hit. Not in the least to push manufacturer 's competition further (M5, anyone?).

I'm on the lookout for my first anamorphic and just saw this pop up, anyone think it's worth the gamble?

To be honest, no...you should be able to find a clean one for the same kind of money. Just wait a little or ask around in the 'anamorphic shooters' Group on Facebook if anyone has something to sell.
