Zooms vs Fixed Lens

[dvollrath]

i KNOW! for pixel peeping it's a drag.

But, I'm reading about people Dumping their 18 -50 / 50-200 BETTER lens
sets for these. for stills!

Why? they get hooked on the ONE solution.

Yeah this is totally a personal decision based on what you're using the camera for. I've just had some bad experiences with these. I once borrowed a friends D90 with the nikon 18-200 and had a terrible experience with it. Some focal lengths would simply result in out of focus images, no matter what I did. Although I'm sure if you test out several lenses, you can find one with a large zoom range that fits your needs.

okay im confused. Does the 1920x1080 cut out JUST THE MIDDLE portion
of the lens? Anyone have a diagram?

In that case one would EXAMINE glass for CENTER sharpness / distortion only then, right?

Edge distorion wouldn't even matter much for video right?

No. 1920x1080 is scaled down. Some of the frame is cropped to make it 16:9, but only on the top and bottom. That's why some people have been complaining about aliasing because the camera scales down from a larger resolution to make it 1920x1080.

Ok, a follow up question... Little confused on the 1.6x and Canon lenses. Does the Canon lenses have to be multiple by 1.6 too or just lenses that are not designed for APS-C? Thanks.

Alll lenses EFS or FF have the same focal length for a number

just if you use a FF camera you get to see more

The OP topic was primes or zooms

I own a pile of prime lenses yet have just ordered two zooms

16-55
70-200

Why when I have a 14 2.8, 50 1.2 and other dream boys?

Simple its for simplicity

Unless you are working in a strict cinema environment filming 3 mins per day changing lenses is a hassle

Especially if you are going to have a FF, maybe Matte Box and some ND filters

You just end up with too much junk to concentrate on

And those wide 1.4 apertures - forget pulling focus with them

so you are going to be shooting stopped down anyway

My take on actually using the camera in a real environment

Im actually tempted by a second one - so no lenses ever come off

DSLR zooms are super light compared to available cine zooms, and the latest Canon and Nikon fixed aperture zooms are really good.
It makes total sense for a single crew/small crew shooter to use zooms.
Only real negative is the focus throw is ridiculously short, but the same shortcoming applies to modern AF primes, so its tough either way unless you're using old Nikon primes or Zeiss ZF and lose the zoom advantages.
