Overachiever - stellar performance in a compact package at a bargain price. [Posted on 2008-06-20]
My copy delivers biting sharpness and snappy contrast over the whole focal length range and focal distance at F/4 or above. As expected, F/2.8 shows a little softness plus the propensity for misfocus on my 40D. The macro feature is tremendously handy. So is its downsized construction. It is my perfect lens for studio portraiture or street candid shots. With the use of 3 LD lens elements, CA is so well-controlled that I cannot detect any PF or color fringes around high contrast edges at any focal length or F-stop. What an optical achievement! I have had no problem obtaining top-notch A3-size prints that show unbelieveable, edge-to-edge clarity. The only shortcoming that holds this lens back is flare problem. Ghosting or flaring is quite severe when a strong light source lies within the frame. I wonder if Tamron has cut corners by not applying the best coatings to its lenses. Reflections from lens surfaces are quite bright and conspicuous - not the deep purple or green hues that I usually see in Pentax SMC and Nikon lenses. Despite this weakness, the Tamron A09 is a well-rounded high-achiever that certainly lives up to its reputation for being a cost-performance champion! Highly recommended.
some good results, but red tinge and focusing are a problem [Posted on 2008-07-06]
I was excited to get my hands on this lens and spent the last 3 days taking pictures of everything and anything. In Arizona there is no shortage of sunshine, so these pictures were under "ideal" light conditions.
First few shots taken from the office window looked pretty fuzzy. I set the camera to full auto and they seemed better. Over the next few days I experimented with various settings and found the lens rather hit and miss with focus. Items that should have been obvious point of focus were not always so. A few "difficult" images of mesquite tress came off with nothing in focus. Comparing to the stock lens, and similar pictures I'd taken with an EF-S lens I'd had, I was rather peeved with it's out of focus images. It was much slower than a canon USM lens and had real trouble in low light finding a focus point too.
I was impressed with indoor shots of fruit using flash, very detailed.
People have remarked on the focus ring turning while you hold on to it, which it does, but you learn not to. The reverse thread is also something you pick up on quickly, so neither of these are an issue I feel.
Also found when comparing photos with the stock 18-55mm my canon XTi came with there was a distinct red tinge to the outdoor pictures taken with the tamaron lens. Nothing photo shop won't fix but a bit strange. Both lenses had B&W UV filters.
Conclusion, I may have had a bad lens, it did work well when it could focus. Build quality was also quite good.It's going back and I am going to spend a few hundred more and get the canon. 6 year warranty was nice touch, but I'd probably stick with a fixed focus Tamron lens on a future purchase.
Good but it's not ALL THAT! [Posted on 2008-07-19]
I compared this to the my 50mm f/1.8 Canon lens (the $100 one). I zoomed the Tamron to 50mm and did some comparison shots at f/2.8. The Canon lens was much much sharper. So much in fact, I don't even want to take any more photos with the Tamron. Based on this experience, I'm upgrading to all L glass lenses. I'll upload my comparison photo which is an up-close shot of a green pitcher.
The lens is a good value and I took some good photos with it. Although, with a 1.6 crop factor, it seems to always be either too zoomed up, or not zoomed enough. I think this lens is targeted at the 1.6 cropped market but the zoom range isn't very useful so that's why I give it two stars. If you know that the zoom range is what you want and this is how much money you have, it's a decent lens.
Very nice at a great price! [Posted on 2008-08-09]
I bought this lens as my in-between lens for my Canon XT. I currently own the 50mm f/1.8 and the Tamron 70-300mm 4-4.5/6. I have been very pleased with it. It has a nice weight to it and is nice and sharp. I highly recommend it.
Good value for the money! [Posted on 2008-08-26]
This was my first non Canon lens purchase, granted the other lenses I've owned has been cheaper Canon lenses (kit lens, 50mm and 28-135mm).
I've never owned an L so I can't compare it to those but here are my impressions:
Price: Can't beat it, its a 2.8 like the better L lenses out there and for a fraction of the cost. Love it!
Noise: Really can't say that its that noisy as I've heard people complain. Again I have not owned an L's so in my limited experience with lenses, its not noisy, nothing I'd consider loud enough to disturb a wedding ceremony or anything of the sorts.
Focusing: It's as fast as my 28-135mm, so not bad, its fast enough to catch my kids running by, get them in focus and me snap the picture.
About the focusing, I did notice mine had a bit of trouble with front focusing, but works well now when I've got that taken care of.
I really haven't had opportunity to test it in the conditions it was built for but so far I've been impressed with it.
Its not really bulky, it seems solidly built even if its not L quality.
The pictures I've taken so far has been crisp and clean and bright, really I cant complain, again a great lens purchase. I can't wait for them to come out with a 70-200mm 2.8 version so I can buy that as well.
If you are a pro with L's in your camera bag you might or might not like it. However if you're a serious hobbyist or working-to-be a pro then this is a good start for a fraction of the cost of an L. Its a nice lens and I don't think you'll be disappointed.
