Got the Tamron 28-75mm F2.8 *pics*

After renting the Nikkor ED 24-70mm lens for a photo workshop last week, I decided I needed to have a standard range zoom.
The Nikkor costs $1,900, the Tamron -- $400. I was worried it would be a piece of garbage but I snapped some pics today at work and around the house and am so far very impressed with the sharpness and colors. There's a teeny bit of vignetting at 28mm but that is due to the full frame sensor I am told.

What do you think? Not bad for the money!

Yes, the focusing is a bit slow. That is definitely true.

Thanks. Altough everything looks sharp at web size I think I will try the lens soon on my 5D II to see what it's all about. The review on Photozone doesn't rate it very good. On the other hand I don't see anything in the sample images I don't like. It's such an affordable lens. Link: http://www.photozone.de/canon_eos_ff/418-tamron_2875_28_5d?start=2

Here are some independent images that show some of the lens problems on FF (the Canon 5D in this case):

Note the combination of obvious vignetting in the corners and extremely soft corners with soft edges.
While there are many circumstances where this really would be acceptable, there are also circumstances where it is not desirable. This would not be a very suitable landscapes lens for full frame cameras, unless you need or desire the effects above.
On crop cameras these effects are much less of a problem, and that's where I think you see the higher level of satisfaction.
To be clear, the middle 80% of the lens is quite good at any aperture and the center shows very good sharpness. It is not a horrible lens, just not my recommendation for FF cameras.
For Canon FF I am very happy with the EF 28-80mm, f2.8-f4L USM. While it has it's own set of problems, they are much less optically than the Tamron above and it is proving to be a very good lens for me on all Canon camera bodies. The biggest problem is that Canon will no longer repair this lens, although some independent shops may still repair it. The used purchase price tends to be on the more reasonable side because of the age of the lens.
The Canon 28-70mm, f2.8L USM is even better and apparently still supported by Canon repairs, although it costs more to purchase used.

Not for the crop cameras as it isn't very wide, but for a FF camera the wide end can be useful for landscapes although not vista landscapes so much. Actually, any focal length can be used for landscapes and I have used up to 500mm lenses for landscape photography. It just depends upon the subject and angle of view you desire. Longer focal lengths are often used to compress the apparent distance between foreground and background using compressed perspective technique, for instance.
Sorry to hijack your thread and I am not raining on your Tamron for crop cameras, it really is a very good choice for a slightly longer standard zoom on crop cameras. At one time it was "extremely" popular and it is still highly sought.

It just focuses too slow for my tastes. If your subject is moving AT ALL it will not work, as it takes about 2-3 seconds to focus, which seems like a lifetime. And by the time you almost get it focused, the subject moves again. Will keep it handy for landscape/flowers and other things but am going to rent the Sigma 24-70mm and see how that does. Reviews say focus is fast and silent, which is exactly what I'm looking for. It's double the cost of the Tamron but still $1,000 less than the Nikkor.
You DO have AI Servo on for fast moving targets, right?
heh, yes I had it on continuous focus (nikon). It is very slow. I'm not doubting your claims but in my experience it is just too slow. Maybe I have a bad copy?
Outside with good light, focus was almost as fast as any one of my Canon "L" lenses. With AI-Server (constant AF) engaged, focus followed quite nicely. I don't have any rug-rats to us as test subjects, so I just moved the lens from close stuff to objects further away. One test was to focus at the side of my house (from 10' away) and re-orient the camera to view things 50' to 100' away. No issues. All focus times where sub 1 second.
Inside with light levels to mimic those found at many receptions - took just slightly longer but didn't do much (if any) hunting.

I'm sending this lens back to Amazon for a refund -- which is the reason for this post. If you haven't used a lens before always make sure they have a robust return policy
