Canon 135L, any difference between UQ and UX

Assuming they are both in great condition are there any manufacturing differences between a Canon 135L made in 2002, UQ, and one made in 2009, UX?

There are no differences. Go for the later date code though, like UX or UW if you can afford it.
Unless the price is really tempting, I try to stay away from anything earlier than UW.

Newest possible. Usually is always better and less wear and tear put on the lens

What would a good price be for a UQ 135L.
Thanks

This is not necessarily true. I've come across lenses that were hardly used in years, while others are almost new and are damaged already.

I'd prefer a newer lens if both were in the same condition and for possible warranty. Other than that, I'd judge the lens based on its condition and performance rather than the time stamp.

From my personal experience with e-bay, the majority of buyers do not even inquire about the build date. Therefore, it seems its the visual condition of the lens that drives the sale price (as well as other generic factors).

When buying a used item, unless you know the seller and the history of the product, there is always a risk. Buying a lens with a more recent build date is better if every thing else is equal. A UX lens might have seen a lot more work than a UQ lens. Who knows.

I would simply push the build date to negotiate a better price if possible. Otherwise, I wouldn't really fuss. 135L seems to be a consistent performer and I haven't seen anybody whinging about their 135L failing.

This image is taken with my 135L, the only used lens that I own. Incidentally, it's a UU.

I think the later one will have the slightly recessed switches (for the focus limiter and AF/MF). This is common to most of the later Canon lenses. It makes no practical difference, but less likely to get switched accidentally. But I have had older ones and newer ones and there was really nothing optically between them.

Age doesn't say anything. It could be that the new one is a bad copy or that is used much more then the older.

But I would also go for the newer one .

If the newer ones go for about $850 would $700 be a good price to pay or even $750 or $800, or would that be too much for a good condition UQ 135L.

If you can get a 135L for $850, that's a good deal. If you can find one for $700 and there's nothing wrong with it, grab it fast. No matter what the year of manufacture.
