aye. and i am not only thinking wishlist, i am thinking money here. make one or two (make a poll on pentax.com and ask the pentaxians which particular old lens they would most likely buy new), and make the first two or three first, see how they sell. you might be shocked. i would also not mind if they carefully choose the lenses available so as not to eat into ltd lenses sales. i think it is worth a try at least for pentax, especially in these days of crisis
on a slightly different note: i would like pentax to also think of something else: i have a zenitar now, and i love it. i doubt if there is anything out there more suitable for my needs (even disregrading the price): it is small, it is light, well built, nice tu use (ergonomics), optically good, and it is also cheap. howcome? well, except for the obvious "the russians made it, and they made it so long ago the r&d is probably already paied for" (see the comment related to blueprints in the original post), i think (experts might want to correct me) it's because it is a fisheye, and it's so much easier to design a good fisheye than a good rectilinear wideangle (less corrections needed), it is also inherently smaller and lighter. so here is what i was thinking:
- fisheye (similar to the zenitar, "full frame" so i can put it on my film body and have fun),
- software bundled with the lens to defish if desired, with preset configuration available for this lens, batch mode and so on (i suggest autopano/nona, just make a donation to them and include that one, maybe also make a small gui for lens corrections alone, corrections of lateral CA are also possible).
-smc coating (so damn important for a wideangle)
-weather sealing (so cheap and easy to do for a small prime, as opposed to a zoom)
- interchangeable hood and filter mount (or just attachable hood/filter mount for aps-c, the one for film stays on at all times)
- the most compact and cheap form of af you can fit in, or none at all
- a-mount compatible, aperture ring, and contacts to talk to the camera (for exif and sr)
- to really blow my mind: firmware upgrades for all current dslrs (and everything at least back to k10d/k100d, just to show this is pentax) to preview the defished image if desired, three simple types of auto crop available in the config for this purpose. (should be rather trivial to do, only for preview purposes, to check the framing, not high quality stuff)
what's the point? i am a landscape photographer, and while i could buy a "proper" rectilinear wideangle (like the 12-24 or one of the primes, like the 14/2.8), i cannot get over the facts that 1. size does matter for us landscapers 2. rectilinear wideangles seem a complete waste of r&d money, space and glass, in this day and age (with the only exception that they will enable one to see the "corrected" image in the optical viewfinder directly)
there is also the cool factor: they will definetly be the first to ack this (digital) opportunity and cash on it, and, again, this being a time of "financial distress", the lower price for excellent quality will sell (and people who realy want rectilinears and can't be bothered with this defishing nonsense will buy the 12-24 anyhow).
am i a black sheep, or are others interested in the idea?
