My Canon glass isn't so hot on the 1Ds Mk. III...
Feb 2, 2013

I have used a 30D for years (well, since it came out, so 6 years I guess).  I built up a few lenses since then:

35mm f/2, 85mm f/1.8, 17-40mm f/4L, 70-200mm f/4L (non-IS).  They all work great on this camera and I fully trust the camera and lenses under any use (wide open, hard lighting conditions, etc.)

Overall, not at all thrilled with what I see on a FF body.

-- hide signature --

The 35mm is pathetic and miserable wide open, but EXCELLENT at f/8-11.

--The 85mm is so-so wide open but EXCELLENT at f/8-11.

--The 17-40mm is decent, probably fine for landscapes and such (corners get soft/distorted).  Not good wide open, but for a landscape lens, not a concern.

--The 70-200 is great at 70mm, but not as good at 200mm (some slight softness on one side).  Not so hot wide open.

Overall, all 4 lenses can look great, but I have to really stop them down to get something that can make use of the camera.

My question is about expectations.  On a high-MP FF body, what should I expect from these lenses?  All 4 worked great on my APS-C body, but on FF, the outer areas quickly degrade to a point they look bad on even an modest sized print.  Do I have bad copies, or is this normal for lower-tier glass on a flagship FF camera?

Do I see a 24-70 & 70-200 f/2.8 in my future?
