Tamron 70-200, 200mm, f2.8 on the K-1

[Dewman]

I've owned or used quite a few ultra wide angle lenses. Over time I have used the Tamron 10-24, Sigma 10-20, Sigma 8-16, Sigma 12-24, and Pentax DA 10-17. I've never had a chance to use a DA12-24. The Tamron has a few drawbacks. Screwdrive autofocus, the build quality is not the best but it is not terrible either, it needs to be stopped down to around f8 for best results or at least the one I used did.

However of all the lens mentioned above if I were to rate a winner based on performance versus value, the Tamron 10-24 would be the clear winner. You just can not beat the value of this lens. The Sigma's had a better build quality to them but cost more as well.

10mm is pretty wide on ASP-C, 15mm Full Frame equivalent. Success will rely on good composition and correct exposure. That is a lot for the senor to take in. I always recommend a tripod when possible with these ultra wide angles. If I remember correctly the Tamron had a very close minimum focus distance which can be alot of fun. I ended up with a Sigma 8-16 since I shoot indoors alot. Places like museums and events really tend to frown on a screwdrive lens whirling around. All ultra wide angle lenses are highly susceptible to decentering. It is extremely important to test for any decentering right away. Tamron lenses are none for quality issues. However when you get a good one you get a great lens at an exceptional value. It took 3 copies of my Tamron 70-200 for a good copy. The most issues I have know people to have with the 10-24 is with the autofocus. Even the copy I had would take a few tries to get the autofocus to catch every so often. It was like the clutch would slip a times, not all the time just every once and awhile. For landscapes I would just use manual focus.

The 10-24 really is a great value. Yes, like alot of lenses it has a few quirks, but nothing that is a deal breaker. As long as your copy is not decentered you should have alot of fun with it.

Michael, thanks very much for your comments. THAT was what I was hoping for when I first posted this, rather than a nudge toward the reviews. As soon as I get this hip joint replacement done and over with, I'm hoping to be able to get back out in the field with my camera and join the fun! Until then, all I can do is participate in the discussions on the site.... ask a few questions and post photos from my portfolio of days past. Thanks again.

Tamron SP 35-80, it has not been out for a while and as I am stuck mainly at home I am appreciating the poppies self seeding. Nice colours while we have some sunshine!

I was out looking for insects with my Tamron SP90 52BB.....
I think these two young birds have eaten them all.
