Originally posted by rlg118 I'm not new to Pentax, having gotten my first K1000 29 years ago, but I am new to the world of DSLRs. I recently picked up a "Used - Like New" K110D for $200 with a 18-55 zoomie, and now I'm looking for a telephoto lens. Due to budget constraints, I am limited to the following:
A. Pentax 21870 DA 50-200mm F/4-5.6 AL Weather Resistant Lens ($179)
B. Pentax DA L 50-200mm f/4.0-5.6 ED Lens (used, $130)
C. Sigma 70-300mm f/4-5.6 DG Macro Telephoto Zoom Lens ($144)
D. Tamron AF 70-300mm f/4.0-5.6 Di LD Macro Zoom Lens ($199)
Was curious to see how the more experienced folks here would rank these (1-4, in order of preference).
Any help would be greatly appreciated.
A) Your camera isn't weather-sealed so it doesn't need the WR version of the 50-200.
B) The price seems a bit high for the L version. Look at this listing,
the DA version. That has the hood, the quick shift, distance scales and metal mount missing from the L.
C) and D) The other posters correctly suggest that the Pentax DA 55-300mm (also in L version) is better than either of these. That's $275-300 tops, less for the L version. The Pentax will be better at 300mm, which is the whole point of a zoom that goes to 300mm. It's a lens you could use for many years without outgrowing it.
Since you have 6Mp, cropping a 200mm image to resemble a 300mm shot is not the best solution. I've used older versions of the Sigma and Tamron and they're not so terrible. The 50-200 is a better idea if 300mm is just a cool idea, not something you really need. Either Sigma or Tamron should be an OK stopgap if you need 300mm right now. Remember you'll need to be pretty steady to handhold a 300mm lens, and you don't have SR on the K110D.
