What are the alternatives to the pentax hd d fa 15 30mm f 2 8 ed sdm wr?
I don't have a true wide-angle alternative to the Pentax HD D FA 15-30mm f/2.8 ED SDM WR on this site. The two other Pentax HD D FA zooms I cover are both longer, so they fill different roles:
- Pentax HD D FA 24-70mm f/2.8 ED SDM WR: the closest in spirit, a constant f/2.8 standard zoom for full frame. It starts where the 15-30mm stops, so it pairs well with it.
- Pentax HD D FA 70-210mm f/4 ED SDM WR: a lighter telephoto, the choice if your subjects are further away.
If you shoot on an APS-C body, the 15-30mm frames like 22-45mm, which is a different job altogether. The lenses guide explains how aperture affects low light and background blur if you're weighing these up.
