I have a pentax K-7 with 2 sigma lenses. 10-20 , 17-70 and I'm planning to buy another sigma 70-200 DG (FF lens ) as 50-135 is not enough for and beside I have hear about SDM failure on that. I shoot portrait, wedding, landscape and macro. I've been told by pro that I need to gear up to either FF or APC-H sensor in the future for better quality images. I'm skeptical about getting K-5 and some Pentax Prime lenses. The best long range Pentax I can get for wedding is 60-250 f4, but I need f2.8 for low light and churches ( wedding mostly ) and yeah I know if I get K5 I can raise the Iso. so if I keep wanna get Sigma and not being able to put Pentax of the same on Pentax camera, what's the point of having Pentax.. Beside with others, even Sony, there is FF or APS-H sensor option...
any feedback would be appreciated..

I think personally you have been told a load of BS,
if you look at the comments, FF or APC-H really just say canon or nikon. and the issue is not "better images" as such. I can only see two areas where the larger format helps over APS-C, and that is in the wide area and in getting really shallow DOF.
You complain about needing more length and the 60-250F4 is not fast enough, BUT what do you want in full frame, to fill the sensor at equal to 250F4 you need a 400F4 lens that is simply not as practical, in the tele end, there is not a great advantage to full frame, in fact it has no advantage at all.
Sure the sigma lenses are full frame, but that does not mean they can;t work on a ASP-C sensor.
the new cameras have good low loght capability and offer sensors that are technically much more advanced thant he sensor in a full frame camera, in fact, I heard something (consider this rumor) sony has announced they will not make any more full frame sensors for nikon, so is full frame a dead issue and way?
