tamron 18-200 f/3.5-6.3mm vs tamron 24-135mm f/3.5-5.6

dfeld · 03-08-2014, 06:31 AM

Hi there,

I'm new to pentax and just got my hands on a k-x. I'm looking for a decent walk around lens that covers a wide range before I figure out which primes to buy. (Though I did buy a FA 50mm f/1.7). Aside from that, the only other thing I've got is the kit lens. So some input between these 2 tamron lenses would be a huge help.

Thanks!

I can't tell you about the Tamron 24-135, but I have the Tamron 18-200, and it's pretty good for a superzoom. Keep in mind on a Pentax DSLR the 24-135 will actually be equivalent to a 38-216mm lens, and the 18-200 is equivalent to a 28-320.

Because of the wider focal range, and wider angle I think I'd prefer the 18-200.

I have the sp24-135 If you can find one get it ! Very very good lens with a useful macro range . I also have the 28-200 good but
Nowhere near the other one, not an SP lens.

I don't have the 18-200, but I do have the 24-135, and it is an excellent lens. My review along with others is here in the database. It is as good or better than the Pentax DA 18-135 in most instances. The DA 18-135 does, of course, is wider and is WR, and it is noticeably smaller and lighter. The Tamron 24-135 was the lens on my K-x until I got the DA 18-135. I'm keeping the Tamron because it's full frame, and just in case...

I can't imagine why you'd be comparing these two lenses: a (still) very expensive, high-end-for-its-day (arguably even for today) full-frame model vs. a small-sensor consumer zoom. If I had a chance to buy a 24-135mm at a good price, I'd jump at it. You'll always be able to get an 18-200mm for not much money, but the 24-135 will always be much more difficult to acquire.

The 24-135mm is a better lens.
