It does apply more to camera bodies
...that was the gist of my thought actually, with changes in bodies, it seems that DA(star limited what have you) or crop format glass is all that is new - i guess DFA is not crop format but point being with all the argument about FOV, IQ and such, why are all the fast lenses 1.5 shorter (ie 50-135 f2.8 vs 80-200 f2.8). Why would Pentax stop production on a known entity like the FA*80-200 with out some replacement... to which northcoastgreg surmised that Pentax doesnt think it would make its money back on a new model - a reasonable consideration with a chance of 3rd parties eating their lunch.

So if you're putting your money in lenses tranq, wouldn't you want to spend on lenses useful on Full Frame instead of just crop sensor size? In the event that the K-5 equivalent for 2020 was actually an affordable FF model, wouldn't investing in a pile of DA glass be a stinker?

Consider all those people with Nikon AF glass from the 90's that was screw driven, that can not now be used on anything but Pro dSLR bodies because all the entry / mid dSLR bodies require SDM type AF lenses... I think they are only now working screw drive back into more accessible bodies.

I equate the proliferation of DA glass to a limitation that might be a hurdle to overcome in later years. I propose that filling the shelves with consumer glass that is constrained by the equipment it can be used on is a strategic risk. Maybe you are right.. M disease

The DA*50-250/f4 and DA* 60-250/f4 lenses are replacements for the FA*80-200/f2.8. The cropped sensor 1.5x factor brings it back up the the "full frame" equivalent. The F4 aperture is to make the lenses a more manageable size since you can adjust ISO, something that obviously isn't possible with a film body. Photography is always about tradeoffs.

All my lenses are full-frame. I don't own any DA lenses.

I wouldn't worry about full-frame versus crop sensor argument, whether it's APS "C" or "H" or any other size. If and when a full frame 35mm sensor comes out Pentax will probably just have a camera setting that allows you to adjust to a crop sensor. Easy and simple.

In any event Pentax's solution to full frame is a bit different. It's the 645D. For 35mm they are obviously sticking to a crop sensor for the time being.

So I think the whole "full frame" argument is a bit of a red herring. If anyone really wants full frame they can buy the 645D. I know that people will still complain because of the high price, but if the 645D sported a Nikon or Canon logo, it will probably be way more expen$ive.

You shoot with Pentax so you have it much easier than Nikon/Canon users. Pentax has always gone out of its way to be as backwards compatible as possible. At some point that may not longer be possible due to technology changes, but as of today you can still even use screw mount glass. I personally find the whole idea of planned obsolescence annoying.

Your mileage will and can vary from my opinion.

Seems like a wise choice.

- Well I framed it as a hypothetical question for speculation. As we both agree Moore's law could really only apply to bodies.
