  1.  

    No, the logic is different: As variable ND filters work in a similar way as very strong polarizers, of course they inherit all their drawbacks as well. Regardless of how much "high-quality" they are. Since polarizers show uneven polarization with wide lenses, it´s quite clear that two filters stacked on each other can lead to quite bad results on wide lenses. This is due to physics and has nothing to do with the quality of the filters.

    See i.e. here:

    https://luminous-landscape.com/polarizers/
    http://havecamerawilltravel.com/photographer/polarizing-filter-wideangle-lens
    ...and many more on the web.

    So my personal conclusion is to get one variable ND filter for work with "normal" lenses and a set of fixed filters for wide shots. 

     

    I think that's the reason those Fotodiox EF-NX adapter with internal ND filter may be more desired than external variable ND.

  2. shoguns are selling used for a lot less than new now, still might be more than you want to spend, but 4k recording, luts, false colors.. Lots of tools.

    Thanks for the update, that's nice to hear. I would really love to have a Shogun when I have the budget.

  3. I'm curious, are any of you using external monitors and if yes, what?

    As you've probably seen me ranting, the SmallHD 501/502 is not compatible with the Samsung NX1 (and probably will never be). But when you look at 5" Full HD monitors there's somehow not a lot around. Of course there's options when willing to use a external recorder in form of the BMD Video Assist (which lacks a lot of the tools SmallHD has and apparently also has a weaker screen) or the Pix-e5 (which costs 1600 €).

    I'm stuck between using my D750 + the SmallHD 501 or using the NX1 with no external monitor... so I can eaither have ok usability and image wiht great easy monitoring (peaking, zebra, waveform, frame guides, ...) or a way better handling camera with a subjectively nicer image but be limited to the little flippy screen.
    It seems there's a lot of sidegrade to the NX1 in form of A7rII, A7s, A7s II, GH4, BMPCC/BMMCC,... but I didn't find a equivalent alternative to the SmallHD 501 (the Pix-e5h is the closest but heavier due to recorder functions).

    I've ordered an Aputure VS-2 FineHD, it's a 7" Full HD IPS monitor, cost about $295 on ebay. It's still on its way but I'm looking forward to it. But it's 7 inch so not as compact as SmallHD 501. I like 7" monitor, very comfortable to work with.

  4. Yeah the idea that the screen is almost twice the size of the camera is kinda silly. The ability to use your iPhone or a small GoPro-like screen seems like the best option, but it doesn't seem possible, or at least cost effective. For me, the best scenario would be the camera on an L-Bracket with a c-mount lens... Talk about a small set up. Hopefully a third party will introduce a smaller screen... Maybe a screen that can hook into the battery on the back... A third party battery that has two terminals... One that powers the camera and another that powers a small screen designed specifically for the battery and BMMCC. 

    Indeed, sounds like a great idea.

  5. As it stands, i think not... But hopefully someone will make an HDMI wifi stream gizmo.

    There is a Teradek Clip which can stream the HDMI signal to iphone/ipad using H.264, but at a cost of 4 frames delay, which I think is quite ok but expensive.

  6. 16-50s is great, but the focus is by wire, unfortunately. The only two lenses which are mechanically coupled in nx ecosystem are the 85 and the 60.

    Actually I think the focus by wire of the 16-50S is quite amazing. It's very precise and adjustable, and the most important, it's "linear", which means I can even put it on the follow focus and it works perfectly and stops where I want. To be honest it's smoother than many canon L lense I've used. It's not the same as those bad focus by wire system many people are complaining about.

    On the other hand, the focus by wire system of the sony E mount lenses is not "linear", if you turn the focus ring faster or slower, the step size of the lens focus changes, and you end up with a wrong scale on the follow focus and it's totally unusable. I'm not sure whether every E mount lenses are like this, but the ones I've used, they are. This variable manual focus step size makes the E lenses quite unusable for manual focus, because it's quite unpredictable.

  7. Debating on getting a shogun assassin for this thing but I haven't seen anyone mention any gains in quality from it. 

    Gonna take @Geoff CB advice and transcode / downscale the in camera files to 10bit prores and see if it will improve the quality of the files. Tried it before with gamma c and raised master black levels and it was a disaster in deep shadows. Had to crush the macroblocking away. fingers crossed

    I'll be thinking about BMMCC with speed booster if I have shogun, it looks a better combo than with the NX1 because of the better HDMI/SDI output of the BMMCC. I think the advantage of NX1 is its internal recording with good quality, just using the camera itself as a whole system.

    But BMMCC is not available yet... Still I'm a bit interested in buying one.

    edit: oops, I mean the BMMSC if I'm right, the micro studio camera with 4k output, which is already available :) 

  8. The Kiwi adapters looks good, and the screws are much longer than the Fotasy, which is only about 4mm long, too short. I'm actually a bit afraid of my sigma 18-35 on the Fotasy, hope the screw can hold it with some loctite.

  9. I think the Novoflex is a good adapter, tried it once and it worked very well. What I'm using at the moment is the Fotasy adapter for Nikon G lenses, does the job pretty well.

    However most of the adapters I tried have slightly some play when mounted, I forgot whether the Novoflex has any play.The Fotasy (Nikon F/G), Kiwi (Canon EF) I have are tight enough but if I turn them with some force they will still move a bit. The quality doesn't differ much, however the Kiwi is not compatible with all lense/adapters with EF mount that I have, some of them just can't lock. I guess it's the chinese m42-EF NK-EF adapters that are too bad.

    Maybe we can also use external battery with a usb cable, but I'm not sure whether it works.

  10. The XC10 seems totally fine for it's intended use (news, drones). 

    I'm very surprised to see the BMCC lower than the Sony A7SII, A7RII and 1DC for "character and rendering". In my opinion it blows the socks off the Sony's for this. 

    XC10 is quite a special camera for its purpose indeed, I don't think it's bad. 

    Don't know why BMCC is lower. I was actually planning to get one instead of NX1.

     

  11. Thanks for the comparison, nice to see more feedback from people who have both cameras.

    They've just blown my mind when I tried each of them, but you get what you pay for. It's just a pity that the NX1 seems to go out of sight in the market. 

    I'm actually planning to buy an external monitor for my NX1. I feel very uncomfortable when I use EVF/OVF when wearing glasses, it just pushes my glasses to my face and that causes something like distortion in everything because my glasses is not in the right place anymore, and I can't see the full EVF, the edge is always vignetting.
