Medium format aside.

Pentax has taken a considerable gamble in not addressing full frame. Not having the ability to bring one to market yet, no concrete plans for ever bringing one to the market. Every person that has the genuine NEED for full frame will most likely completely ditch their existing Pentax system in favor of investing all of that money into full frame.

Take a look at the sales numbers. Not just for Canon and Nikon, but how about Sony - how about Sony sales of full frame? Even with such a limited inventory in items such as Sony lenses and accessories, Sony full frame is outselling ALL of Pentax.

Sorry but I do see Pentax going anywhere soon, anywhere but down in numbers - considerably.

Take a look at the present Pentax camera body line up and even worse the current Pentax branded PK lenses. Pentax has the ABILITY to do it, but is not doing much with it. The pacing is incredibly slow.

Not opinion, just fact

Cannot help but notice the SDM issues myself.

I have both the Pentax DA 300mm and also the Sigma 300mm f2.8. The difference is beyond belief. While the Pentax lens is considerably smaller and more lightweight, the Sigma is of considerably better quality all around: better build quality, better optics, and the best part considerably better focusing.

I presently have three computer systems: The most fully upgraded consumer Mac one can purchase; booted to both Yosemite and W10 (not a typo W10), another 12 core laptop also tethered to a secondary monitor (tri-boot), and a third pc server.

I sincerely like Mac for most things; the name Mac all by itself, most of the operating system (although there were some major WiFi issues), etc...

But even though the MacPro 12 core is indeed maxed out (again the 12 core), also with dual ADM 700's, etc... Somehow it just doesn't make the screen presentation that a pc does. Sad but true.

I really wouldn't mind boosting up my present MacPro 4k screen a bit higher, or looking better in any way

Some mentioned, some not...

I would avoid the FA50 macro. While optically it is one of Pentax's better lenses, and it also has the very clear benefit of being a full frame lens... The lens sometimes has to hunt for focusing. Not that it should effect most macro subject, but do not try it at portraiture, one will typically miss a lot while the lens fully racks focusing; from infinity, then all the way to the closest focus setting, and then all the way back again

Chances are Pentax will most likely even have 4k video in one of it's flagship models in a year or two; which would be a sincere game changer - even more than full frame.

Take a look at the price of the Canon EOS 1d C variation. Also even the attempt at a smaller version the Panasonic GH4.

On the down side... Shooting video at 4k, and then wanting to later edit it would also spell out quite impressive computer specs. Find me a system that does 4k editing effectively at less than 2k euros

Because Sony is taking massive steps that Pentax is afraid to.

Sony has full frame, and take a look at the variety of full frame. Sony has cameras such as nex. Sony has quite the line of pocket cameras; some even having 20x optical zoom in a nearly pocket size. Sony has the entire camera line covered, except medium format (but naturally the same can be said about Canon and Nikon on the medium format).

More about the Sony camera line, take a look at those prices; from entry level pocket digitals all the way to their top of the line full frame. Compare those prices with Pentax's existing line. Which is just another reason which forces Pentax into more of a bind. If Pentax ever does come out with full frame, it will almost have to be at the same price levels as Sony. Could that ever really be possible??

Also look the stats of the big three; even the complete sales figures for still digitals. Then take a look at the entire sales numbers of Pentax.

Sure I have more than a fair share of camera bodies that still have that Pentax label on them; and an extraordinary line of lenses, although still somewhat limited (due to PK lens availability restrictions?? I'm not the only one out there that is seriously beginning to question Pentax. It's unfortunate. Really like some of their current items, but can they really compete? Plus also imagine, how many people out there will have a genuine need to have a second system, such as a Sony or a Nikon. Because each and every time that anyone needs to look outside of the Pentax label, then hoping that the person will not permanently give up on Pentax

Mostly training and sales. Lets all stop by and ask them about full frame

It's the work of the devil

Depending upon settings that were used for capture and/or computer processing the image; strongly weigh the option of printing off a few METAL copies

A lot of people out there (in general) like to "weigh" the options for lenses in both size and weight. I personally prefer to toss both of those options; I go for best optics and preferably best apertures = which means typically sacrificing both size and weight.

The Pentax limited glass is above average. For glass, the Pentax FA's are quite impressive. One might want to strongly consider Sigma as well.

Even remaining in PK... Look for lenses that will reach out to f1.2 next year, and will also be a full frame variation lens, but not under the Pentax label or also the FA designation that Pentax uses. Possibly even f0.95 . Imagine the lens and filter sizes
