Hi. Using a drugstore lab for quick travel shots I noticed quite a bit of chromatic aberration (red separation out of white usually) with my 35-105mm/3.5. But when I look at scans from my slides using same lens, I don't see any. And I always hear everyone saying how good is their 35-105mm/3.5.

So is it possible that one lab can produce more chromatic aberration than others? Did any one found excessive chromatic aberration with 35-105mm/3.5? Or could it be that with some films it can produce more?

Thank you.

I would say to have those shots printed at good lab. If the lab is using a analog system (optical enlargement) their lens could be giving the aberration.

I have not noticed any chromatic aberration with my 35-105 with slide or print film.

Well to produce a print (conventionally) you need a lens. This lens could be the source of any number of aberrations. I would trust the slides, assuming the subject has a similar contrast. You could also try reprinting your negs at a lab you trust.

If your slide don't show any chromatic aberration, your lens is free from chromatic aberration.

Canon lenses are remarkably free of those nasty old chromatic distortions and a lot of distortions. Zoom lenses like yours may have a touch of barrel distortion, but not what you see,or think you see. Keep out of the drugstores. Rhue.

Pil,

I have had this problem with the same lens - and others - when the prints have been done at a 'cheap and cheerful' processor.

Get them reprinted at a quality processor and you should see a dramatic improvement as your lens is capable of producing excellent results.
