for what a 50-135 is worth you could get a couple of faster lenses for your arsenal (ie the FA 501.4, the DA35f2.4 together are about half the price of the 50-135)Ĭan somebody please tell me what type of lense would be best, taking in to consideration all the other lenses I have?. IQ wise it really doesn't get any better in a zoom. IT is a WR lens, you don't mention which camera you have but Weather sealing can be very nice to have. a very popular and useful length (witness all the 70-200 that are still on the market, they are almost all holdovers from film days though usually with updates in design)Ģ.8 is fast enough to give good bokeh, and has enough DOF to capture subjects in focus pretty consistently. in the old days it would equate to a 75-200 on a 35mm Camera. second drawback is of course it is one foacla length (albeit a very useful one). Drawback is at f1.4 it will be hard to nail the right focus with a moving subject like your kids so you are much more likely to shoot f2.8-f4.0 to capture focal zone. 50 mm is pretty close to an ideal portrait length.Primes Typically have better IQ (sharpness,contrast colour rendering) than Zooms. Second advantage is wide open you will get much nicer Bokeh (out of focus area). The advantage to the fa 50 is it is 2 stops faster allowing you to shoot in lower light without flash at a reasonable shutter speed. Thanks for any input you can give me! :-) I could probably manage to bring an additional lense, but ideally as few as possible would be ideal. We live in the country and most of the time when I go outside, I grab my camera, with the lense attached and go. I do, however, do a lot of outdoors shooting. I just want something with a lower Fstop and that is a good all around lense, especially for those candid portraits of my kids. I thought I wanted a telephoto so I ordered a Tamron 70-200 f/2.8, but I decided my old 70-210mm works just fine for all my telephoto needs. I take a LOT of pictures of my kids and want to get the most bang for my buck.Ĭan somebody please tell me what type of lense would be best, taking in to consideration all the other lenses I have? Like an 85mm lense, does that mean it is a fixed 85mm?ġ) SMC Pentax 1:4 70-210mm lense (it was my dad's)Ģ) Pentax DA 18-55mm f/3.5-5.6 WR lense that I bought with my K-5ģ) SMC Pentzx-FA 1:3.5 1:3.5 100mm macro that I had with my slr PentaxĤ) SMC Penax-FA 1:3.5-5.6 28-80mm that came with my slr Pentax I am still unclear how the mm numbers relate to the lenses.

I really want to get a lense with at least an f/2.8 or lower.

Ok, well I got a little bit of extra money from work for some reason.not gonna ask.
