I think the new K-r is great but as much as I love my Pentax cameras and lenses (and I've owned quite a few), I stand by my disappointment with the new DA 35mm f/2.4 notwithstanding the fact that there are no IQ tests done yet. Does Pentax need such a lens... most definitely, there is a pressing need to fill the gap for a cheap kit prime. I take the view that more lenses in the line-up are better for everyone, and I might buy one myself.
However I strongly feel Pentax has made the error of producing a lens that lacks a maximum aperture comparable to budget offerings from Nikon, Sony and Canon. Unfortunately we don't have a choice in the matter as we're all locked-in to the K-mount with our Pentax DSLRs. We may never know why they opted for f/2.4 but what a missed opportunity, so I'm calling it as it is.
I see plenty of frankly laughable remarks defending the new lens, some of which are pretty questionable if not condescending.
Sort of along the lines of:
- oh, it's for newbies, they don't need f/1.8 or f/2... they are better off with f/2.4 cause they can't handle the larger max aperture due to thin DOF and f/2.4 is good enough, and their pictures will be sharper...
- f/1.8 is soft... so you need to stop down for decent sharpness... so you're gonna shoot at f/2.4 or f/2.8 anyway... besides, I don't shoot at such wide apertures... so f/2.4 is good :ugh:
- high ISO takes away the need for a faster lens (bunkum)
Well I sincerely do hope this lens (when we can do the IQ tests) is stellar from f/2.4 onwards but there's no escaping the fact that lenses past and present, prime or zoom are never their sharpest at the maximum aperture. With even a half stop or a full stop difference in max aperture, it will have an effect on the range of apertures to shoot for maximum sharpness. Perhaps we forget the effect of the aperture - DOF, bokeh, viewfinder brightness, ability for the camera to lock focus in AF, ease of manual focusing, subject isolation, etc.
This lens will be a runaway hit... if only because of price, versatile focal length, (and color too) but prepare to see lots of snapshot kind of images coming your way soon.
It's all good when you shoot a Pentax, just don't ask for large maximum aperture budget lenses. In a way this lens is keeping with the recurring theme of most DA lenses... nothing faster than f/2.4...
