ZEISS Compact Prime VS. low Budget Sony Lens on FS700

[maxemanuel]

Nothing professional, just went out a view minuts and did some shots - (i know, next time I'll set up 30p instead of 25p) quit surprising results...

A view pictures shot with on a Sony NEX-FS700 in use of a low budget Sony SEL50F18 50mm /F 1,8 lens and an extremely expensive ZEISS Compact Prime CP.2 1.5/50 Super Speed lens.

Thanks for sharing. What is surprising about the results? The CP.2s are just re-housed manual still lenses, the reason they cost so much is the added precise mechanics, design and markings catering to a cine market which is a smaller market that makes the costs even greater. The other added draw of CP.2s is their circular aperture. I never really expect CPs to perform much better than mid range still lenses otherwise. Other than that, it's a bit subjective for each user whether they prefer the Zeiss look or something else.

A more useful comparison might be made from a video that had some focus pulls to compare how the two lenses breathe or some distinct points of light out of focus show the evenness of the bokeh and aperture rendering throughout the field of view or internal vignetting etc. I imagine it may be quite hard to do repeatable, precise focus pulls on the Sony lens. Of course there is also sharpness and CA which are big ones, and it looks like the Sony has a bit more CA when macro focused, but most modern lenses don't have much trouble keeping CA under 1px and rendering very sharp images even wide open on HD cameras that only deliver 2MP of resolution.

sad to see the stutter on the faster pans. Till we have Global Shutters nictpicking lenses will not matter that much

Thanks for your reply Noah. Pulling the right focus with the Sony lens ist kind of impossible while shooting life. I tried a Canon 85L 1.2 lens once and there was the same problem, no direct contact to the focus - only electronically wise. Like I've said this was nothing professional, just a short try in a 10 minute break. I'm pretty sure the Zeiss will show it's quality in many points but I was expecting just a bit more differences yet. I'm going to do some backlight shooting combined with trees. Don't get me wrong I really do love my CP2 and I still think the manual way is the best. I tried that FS700 Facedetection, Focus-Focus etc. and it's nice somehow but not usable while working on a real set. On the other hand, moving the camera on a slider and same time changing the focus manually is a bit tough - but still possible. This would be the only situation where a automatically done focus change would be a bit more easier and perhaps better.

Stutter is related to framerate and shutter speed, not rolling/global readout. If you don't want stutter, shoot longer shutter or higher frame rate, both risk making your footage look a little like video/news footage. This is why Peter Jackson shot The Hobbit at 48fps with a 270deg (1/65th) shutter.

I see. But I see that stutter on most fast pans using rolling shutter at all but the faster rates. Thanks for the education on this.maxemanuel take note sir
