Gives you a field of view of 27-375mm equivalent if you were using a 35mm SLR. This lens for aps-c only. Not sure how sharp the telephoto end will be but this definitely stretches the all in one concept.

probably goes to crap beyond about 200.
The old Tamron 28-300 film lens was all but useless beyond 200 for anything above a 4x6 print

I think the Sigma 18-200 OS has a chance of success. This tamron is dead in the waters...unless they come up with a miracle.

That's the idea, sell the "bigger is better" idea though optically it may not be optimal just like pixel density going higher is not a good thing all the time.

In my 35mm days, Sigma made optically good lenses that fell apart in a year or two.

maybe it was just you. Mine survive explosions periodically. Really.

Depend on the lens, most of the newer ones and EX series are pretty decent.
