Bill - I appreciate your taking time to reply and you have piqued my curiosity and revealed yet another area of ignorance. While I have heard about micro adjustments to focusing to "mate" a particular lens to a particular individual camera body, I had not heard of "tuning to specs" in a generic way. Does this mean it became less effective on the 6d FF after the tuning?. Do many people do this and does it apply to all lens FLs ??

thanks

The Canon 7D Mark II came out after the Tamron lens. So, the data about the camera is not installed in the chip in the lens. This data helps with focus, and lens connection. Tamron also made a deal with Canon for the focus data used for the lens. If a new lens has a problem with front/back focus it is necessary to make micro adjustments. I like to use a program called FoCal, and run all my lenses through the program to each of the bodies. Both of my main bodies will do micro adjustment, and store 20 lenses data.

I have been debating pros and cons of the Canon EF 24-70mm f/2.8L II USM Lens and the Tamron SP 24-70mm f/2.8 DI VC USD given the substantial price differential (currently 1800/1200 USD at B&H) as a replacement walk around for the 18-135 f 3.5 -5.6 EFS kit lens that came with my 7DMII.

dpreview fora and amazon review comments speak of people having to send back multiple copies of the Tamron before they got a "keeper" and there are several folks who seem to apparently find the Tamron VC effect disconcerting. However the constant 2.8 with VC for a walk-around lens seems to make the Tamron a rather sexy proposition - especially given the price differential.

This dilemma was made worse when I saw that in the UK (where I am currently), the price of the Tamron on amazon.co.uk is currently 547.09 GBP (after a 100 GBP cashback refund) - which is equivalent to 852 USD - i.e half the price of the Canon in UK or US. There is no equivalent sale on the US Amazon.com site.

So I am in need of help from the forum:
1) Anyone know if Tamron are discontinuing this lens or bringing out an updated version that might explain why they want to sell these cheap in UK?
2) Do any hogs have experience of sending copies of this Tamron lens back - in which case what defects did you see? DI d you keep a copy in the end or migrate to a different lens?
3) I know I should be a good enough photographer not to need a 4 stop VC assist for getting sharp photos but it sounds like a real plus for low light alongside the constant F2.8

Am I missing something obvious as to why buying "the brand" and sticking to Canon would be the more sensible decision (which was my thinking when I bought the Canon 70-200 2.8L II which is a wonderful lens) rather than getting this "cheap" Tamron VC as a walk- around.

Before anyone asks, I also have a wide angle 10-20 f3.5 Sigma so it really is this intermediate 30'ish to 70'ish focal length range that I am trying to fill in with a faster lens.

As usual with a GAS attack, my disturbed state may settle if I get a range of views from folks with more experience than me!! So I will appreciate any and all views

thanks in advance

I have been debating pros and cons of the Canon EF... (show quote)

I debated the same issue for my Nikon camera and went with the brand name because it was sharper at the extremes.

Interesting comment GrandmaG, I saw those reports in some of the detailed reviews and the effect did seem quite dramatic in the examples but I was quite swayed by one of the earlier commenters to this post who implied that perhaps this FL range lens might spend more time on centrally focused subjects than full landscapes (especially on my cropped body where 24 mm is not that wide).

I have the Tamron now and am still in at least 1.5 minds about it! From the preliminary run, it certainly will not be my sharpest lens but it is a lot better than the kit lens it would replace and, with the money saved, I can get my coveted MP-E 65 mm supermacro as well
