  1. I suppose I'm leaning toward the nikon 28-70 , but I'm just very concerned about focus throw. I've read it's about 70 degrees which seems like it'd be dreadful if you ever had to track a moving subject. 

    Can you use follow focus and maintain zooming capabilities ?

  2. I do agree that f3 footage looks great. As to whether its image beats the f5, who's to say? There seems to be like 3 people in the world who own that camera haha. There's tons of great f3 showcases out there. F5 not so much.

    I mostly use primes, but I have 2 zooms that I like: Olympus 12-40 for m43 and Contax Zeiss 28-70.

    The Contax Zeiss 28-70 is way easier to use then the more professional 28-85. It's also lighter and has more blades. I love it.

    Do you care to show something shot on it? I'd quite appreciate it!

     

    Same for the Bourne lens (having trouble finding footage not from Bourne haha)

    What's the camera mount and sensor size and lowlight 

    Would be used on an a7s so full frame and I have a Nikon adapter. And I can get pretty much any adapter so that's not a concern.

  5. Hey everyone,

    I'm looking for a mid range zoom that's suitable for video for $1000 or under.

    I'm looking for something like a 28-70/35-105, even a 35-75 might do. I would prefer it to have manual aperture and of course the manual focusing has to feel good and be usable. 

    I know vintage zooms aren't usual that well regarded but it seems that new zooms never have manual apertures so that's concerning.

    I've been looking at

    Contax zeiss 28-85 f3.5-4 : big and not a constant aperture. Otherwise appears to be pretty nice.

    Contax Zeiss 35-75 f3.5 : good size, smaller filters than the 28-85. But obviously a limited range.

    Pentax 35-105 f3.5:  interesting range. Cheeeeap. Seems pretty decent optically.

    Vivitar  Series 1 28-90 f2.8-3.5: can't find a lot of info but seems interesting. Not constant aperture.

    Tokina 28-70 f2.6-2.8: pretty well regarded, no?

    An AF 28-70 f2.8: any of these suitable for video work? Let me know! 

     

    I'd appreciate any and all suggestions. Some weird , overlooked Soviet lens? Sure!

    Cine zooms are a bit out of my price range. $1000 tops. Prefer 500 or less. Thanks everyone!

    Kristoferman, I think the Kinefinity guy meant that 6K version will be released one month from now and 5K version two months from now - putting them at the end of May and June, respectively. 

    Yes that is correct, sorry for the confusion.

  7. Looking at Sony primes, xeen primes, Schneider primes, or rehoused stills glass. In any case you'll still be paying thousands per lens. 

    I think our friend rich here sells his DSO in PL!

  8. I've heavily considered the f5, but unfortunately there isn't much of a community for it.  The f3 and even f55 are more popular it would seem.  As such, there isn't a ton of compelling footage out there , but in my research I found it to be a pretty fierce competitor to its contemporaries. 16-bit raw with a recorder! Flexible mount. Ten bit out of camera. Good low light . 14 stops DR. Slog 3. Well built. What's not to like?

  9. I have a set of nikkor ai-s primes I get a lot of use from. 

    Really need some zooms that can match those well though.

    Was looking at the 35-70 contax zeiss and the previously mentioned tokina pro atx 24-70. Not sure how they fare in ease of use for video though.

  10. In case you were replying to my other comment, then specs guaranty what a card can do. When you are going out of spec then you have to run tests on your own to make sure each card is up to the task and I doubt many professionals have the time. Even in the case cards run at higher write speeds than what they are spec'ed for, you can still have dropped frames depending on the state of the card, how full it is, how old it is, what batch it is etc. That is why there are SD specs so you know what a card can consistently do and what it cannot do ... Anyways, I am sure professionals can use whatever they can to do the job and that might include shooting RAW with BMPCC or even 5Diii, but if I was one and wanted to shoot 4K RAW for paying jobs, I would invest in an Ursa mini instead.  

    I did mean to quote your other post haha.

    But yes i definitely do see what you are saying. 

  11. Currently I doubt Sony can make SD cards record 4K RAW with a new firmware. 

    A 4K DNG frame without debayering is ~13MB.

    24frames/sec x 13MB = 288MB/sec 

    Currently the fastest minimum write speed of SD cards is U3 (30MB/sec).

    So you would need around ~10:1 compression which would need a fairly specialized chip that I doubt FS5 has. 

    if anything, I would assume professionals could figure out which sd cards were compatible with their $6000 piece of video equipment
