Canon EF 28-105 F/3.5-4.5 II USM

Review Date: May 9, 2007 Recommend? yes | Price paid: $229.00 | Rating: 9 

 
Pros: Best bang for the buck as far as image quality goes. Great performance from a nice little package.
Cons:
Zoom action feels a bit 'jumpy', but this may improve with time.

I bought this lens new, primarily as a walkaround lens for my EOS Elan 7e. Rather than load up some film, I tried the lens on my 30D. All of my test images were very sharp and crisp, from close-up to distance shots. The test images were shot in RAW and needed very little PP. To be honest, I was pretty much surprised at how well this lens performed, even compared to my 24-105L. This is an awesome little lens, and I would highly recommend it.

Pros: Build quality, great range, crisp/clear images, good color and contrast, great lens for the money
Cons:
A bit soft wide open

This was the first lens that purchased for my 30D. I wanted a versatile walkaround lens before getting additional lenses. At first, I was a little leery about buying a Tamron lens until I read the reviews here first. Tamron has definitely improved. Even though its a bit soft when wide open, once stopped down it takes razor-sharp images at all focal lengths. After getting the lens, I took several shots of a metal horse barn as a way to test out the sharpness. Since the metal panels have many seams and ridges, I figured that this would be a pretty good test. I also took additional shots of the same barn with my 17-40L. When comparing the full size images, the sharpness of the Tamron almost equaled that of the L lens. Its that good. I'm very satisfied with this lens, and would definitely recommend it as a good, everyday walkaround lens. This is still my primary lens.

Pros: Build quality, balance, range, bokeh
Cons:
Sharpness

Maybe I have a bad copy, I don't know. I tried many shots at various apertures and focal lengths, but neither seemed very sharp (all were taken at ISO 100). Most of my neighbors have metal horse barns, so I figured shooting the barns would be a good indicator of sharpness due to all of the vertical lines in the barn siding. I wasn't very impressed with the results. The pictures looked good when sized for the screen, but at 100% the lens limitations became obvious. No amount of USM seemed to make them acceptable. Looks like I'll probably send the lens back in exchange for the Canon 100-400 IS zoom. Its a bigger dent to the wallet, but if I keep exchanging the Tamron in order to find a decent copy, I'll probably spend the balance in shipping fees. Too bad...the Tamron is built and balanced really well. If the picture quality had been better, this would definitely be a keeper.
