Originally posted by fashionista Hi, I've had my Pentax k10D for about a year and I want to upgrade my kit lens with a lens with a lot more zoom. Any suggestions on a sharp lens that is worth investing in? I've noticed my kits lens isn't as sharp as I've seen other lenses. Any suggestions?
Lots of them. Get your check book ready
Actually, you need to start thinking "Whole system" before you buy anything.
I do not know your interests, and that is important, but assuming that you are a bit of a traveller, or like to take photos even within your own city, eventually you will want to cover a range of 10-12 mm at the wide end, up to at least 200 mm at the long end (Maybe 400mm if you do wildlife).
This will be achieved by most probably 3-4 zoom lenses and perhaps 1-2 specialty lenses for things like macro's.
My kit began during film, and is a mix of manual focus primes and auto focus zooms. in total it is 14 lenses, so you can wind up with a lot of things as time goes by.
My basic "travel kit" is 4 zoom lenses, plus a telecvonverter.
- Sigma 10-20mm
- Pentax FA-J 18-35mm
- Tamron 28-75mm F2.8
- Sigma 70-200mm F2.8
- Sigma 2x teleconverter
This gives me a fairly compact 10-400mm range, all lenses overlap somewhat so I usually don't get caught needing to switch too often.
If I take wild life out of the equation, I can drop the very heavy sigma 70-200 plus the teleconverter, and add in a 135 F2.5. This gives me some reach but is very light in comparison. I can also drop the 18-35 and just live with the gap between 20 and 28 mm.
It all depends on what you want to shoot.
