Low cost zoom lenses

[Victor Papalucas]

Hi all,
Can You tell me which low cost zoom lenses should I buy?

It would be great If you post some samples.

Thanks

Depends on what you want to do with it and what mount.

Red 18 50
Red 50 150
Cooke 25 250 mk 2
Duclos Tokina 11 - 16

COOKE 9-50 for a 2K Zoom

COOKE 9-50 for a 2K Zoom

My choice for a 2K Zoom is the Cooke 9-50

For frame grab see thread below

http://reduser.net/forum/showthread.php?t=33173&highlight=Cooke+zoom


Modest in price
Covers Red at 2k 16x9 without the Super 16mm conversion
Little to no breathing
Performs well through all focal lengths
Pleasingly warm and vibrant
T2.5 - so, not too slow
With a manual WB the lens will match no-Cooke lenses fairly well.
Great for SLO MO!!!!

Yeah, great for SLO MO. But I would not recommend shooting 2K unless you need framerates over 60fps.

You can pick up a used RED 18-50mm zoom for less than $4k these days.

Why not?

It's mostly a depth of field thing for me... sometimes I want to replicate a super 16 DOF and not go 4K... I'll admit it's simple nostalgia for shows I remember as a kid but do you have a technical reason for not shooting 2k that I should be aware of?

Just curious.

PS I also shoot anamorphics for the opposite reason... extra depth of field - cant wait for FF on these cameras.


You are right... RED 18-50's are nice... esp for their price but for 4K shooting I'm saving for a 20-60 Cooke... but that's just me.

 

[Curran Giddens]

If you consider that after debayering 4K, what you end up with is more like 3.2K. And 2K is only 1/4 the resolution of 4K. You are losing an aweful lot of resolution by shooting 2K. It's even less than 1080p. That is why most people only shoot 2K when they need over 60fps.

I just read a post by Dominic Jones who explained it all very well:

Next, you don't state what final resolution you are shooting for, but as you're framing for 4:3 I'll assume it's an SD finish, in which case 2K should be fine. If it's a 1080 finish (or even 720, really) then I would very strongly suggest you stay away from 2K as far as possible. Due to the bayer design of the sensor, plus the noise characteristic of the sensor which, whilst quite pleasant imo, will be higher than you might like without some oversampling, I tend to find that shooting 2K for a 1080 finish should be avoided except where you need framerates that are not available at higher resolutions. In this case I would suggest you shoot at at least 3K for any on-speed shots (and 4KHD would be the natural choice as it downsamples to 1080 and 720 better and faster than any of the other modes), and stick to 3K for any shots up to 60fps. In 3K mode you can shoot up to 50fps in 16:9 and 60fps in 2:1, which will still yield a better final image than 2K 16:9.

nikkor 80-200/f2.8 : Police Dog @ 48fps

nikkor 80-200/f2.8 : Police Dog @ 48fps

http://www.vimeo.com/6598096

I paid 850.00 for my nikkor zoom.

Here is a police dog video I shot for a friend(just training).

No ND; I shoot around f8; the out of focus is a little strange Just the one lens...

I should have used the extra light and ran a faster shutter.... (black hawk down)


BTW really cool dog; super friendly... but he gets serious real quick... the last shot gose realtime for a little bit...
