Originally posted by Pentaxor hmmmmm...... a 70mm f2 macro looks to be an interesting and promising concept. although I'm highly doubtful that Pentax would make such a lens a DAL just to make it more affordable for most consumers. for me, a move like that wouldn't make sense, especially for a lens with such potential and could offer a high premium by making it another LTD quality macro in the short telephoto end rather than cripple it. besides, it would cannibalize the sales of both existing DA70 LTD and FA77 LTD if they were to price the hypothetical 70/2 macro around $300 which isn't really a good move. doing such will only seal the fate of the two other lenses. such a lens would be price around the Tamron 60 macro and it's fortunate for Pentax that the Tamron 60/2 is not available for the K-mount, otherwise it could be trouble for Pentax lenses. the Tammy lens for example is not exactly the best in terms of cosmetic build, yet it already commands a significant premium just by the optics alone. so I can't envision a Pentax 70 macro to be any cheaper at all. pricing this lens is rather tricky since it's aperture is nearly identical to the FA77 and the focal length is the same with the cheaper 70mm LTD. it can't go cheaper than the DA70 and can't be priced along FA77 unless they purposely discontinue the FA77 and the priced the 70/2 around $900 if it performs better than the FA77. the DA70 will remain as the budget lens while the 100 WR would be more for rugged all-weather telephoto macro use. the 70/2 would then serve as a classic short-tele portrait/macro lens.
Completely agreed but I meant 1:2 macro and was not referencing the aperture. I didn't even think about what aperture it should be at. It cannot be too fast because 1) there is no way Pentax could make a "cheap" 70mm at F2 with macro 2) if they some how did, like you said it would literally kill the sales of the FA and DA.
So like Ron said below how about a F4 lens? I would still be very interested in a lens with those specs.

DA-L 70mm/f4 1:2 macro
So it is a moderate fast lens (f4) with a moderate macro function, not 1:1 but 1:2 enlargement. Wich is still an enormous step forward since kitlenses get to 1:3 for 18-55 and 1:4 for the 50-200.
