Good AF motor. Not too big or heavy. To approximate its optical performance, it's good at 100mm, Ok at 200mm if you stop it down a bit, and sometimes OK at 300mm if used around its optimal aperture ...

Mine is the 2006 lens. I suspect the 2009 lens to which you refer is the version with Image stablisation, which apparently has inferior optics. My only real bugbear with it is that there is some ...

In either case, just download the correct profile.

Interestingly I and many others have found that the "battery health" indicator doesn't actually seem to measure battery health at all. Instead, if it is is measuring anything, (that was silly, I'm ...

Again, many thanks for your input. My experience with a Mkii has also suggested that this is an extremely sharp lens. I was reminded about the rarer Mki and became curious about its higher price ...

Thanks for reporting your findings. Optical Limits (I still think they should have stuck to Photozone) have only tested the Mark ii, and only on APS-C.

Thanks. I'm not expecting a rush of replies as I realise that very few of us have much interest in this stuff. I have and use the 24-85 on my 6D. I love its small size and great zoom range and it ...

My experience with this lens has been similar. Edge sharpness is not at all impressive compared with other ultra-wide zooms. Since I often find interesting things at the sides and edges of ...
