Thanks everyone for the tips (though now iīm not so sure it was a good idea to ask for advice to pentax devotes, haha)
I am meeting the buyer today to check out the glass.
Originally posted by seventysixersfan I have both a DA 21 and a F 28 and find that they do not overlap or compete too much. Yes, the focal length is a little close together but I use the lenses for different purposes-- DA 21 when I want more landscape shots and wider angle, and F 28 when I want a great "normal" perspective. I think the F 28 is a bit sharper wide-open than the DA 21, and it's a touch faster speed, so all these considerations helps keep the F 28 on my camera. But I love the small compact size (including hood) of the DA 21. I find that I rarely use my DA 15 anymore now that I have the DA 21; I only reach for DA 15 when I want a particularly dramatic ultra wide angle shot. But YMMV.
Seventysixersfan, comparing the DA21 to the F28, what do you think about color rendition and contrast? Iīd love to buy the DA21 just for the its mechanical quality and size/wieght advantage buy it is not enough to justify the price. (paid U$D 170 for the F28)
P/D: Just made a quick test:
The kit lens @21 and @28 and the extra 7mm does make a difference indoors.
Tried the F28 @ f2.8 ISO800 the camera goes for 1/25 shutter speed
@ f3.2 ISO800 - 1/15
Both handheld, without recomposing, same exposure
