Hey folks!

I'm looking into doing a local trade with a someone who's offering their 24-70 for a 24-105 + $100 CDN. Reason being is that while the 24-105 does offer a variety of focal lengths + IS, i'd rather take the faster lens for the type of work I do.

My question is which date codes for the 24-70 are "good versions"? i'm hearing many people saying that their 24-70 had soft focus issues and so on. While the mark ii version is to be released soon, the cost is what is holding me back.

thanks for the feedback!

there is a great article by Roger Cicala and his team at Lensrentals.com about variations in lens quality. He specifically addresses the 24-70mm lens. Essentially, some of the soft "bricks" are a result of a worn plastic collar inside because the lens has been zoomed in and out too much.

I don't see how date codes would favor an older vs newer lens of this type. I have an 8 year old copy that has always worked well for me. Is the zoom more likely to be worn? Perhaps, but the zoom ring feels really smooth with no slop.

a common belief is that certain datecodes are either cursed because of bad karma on the Canon production line or had design flaws in the lenses that were corrected in later datecodes. For some it is far easier to accept this belief than accept the fact that the pristine looking lens they just bought on CL actually has a lot of miles on it and has worn parts inside.

The truth of the matter is that you actually have to test whatever lens you get, because there are some winners, and some clunkers, right out of the factory--even now.

In terms of monetary value, newer date codes are more desirable and are worth more, given matching cosmetic condition.

We've had enough lenses (about 8,000) pass through our hands to see a few instances where there seem to be 'bad runs'. Usually things like a high incidence of electronics board failures, or one run where decentering was common. But date codes are too blunt of a tool for that. Serial number runs (first 2 or 3 digits) sometimes are helpful.

But on a lens like the 24-70 or 24-105 there may be 12 or 14 serial number runs in any given year, so date code isn't going to be of help. The single incidence I know of where date code is a reasonable predictor is the Canon 400 DO, and that's a lens that has one serial number run every year or two.

With regards to the two specific lenses, older 24-70s that are much softer at 70mm than the rest of the range probably do have worn collars. 24-105s tend to age very well. They're probably the most durable IS lens we carry.
