I cannot agree more than. I have a close friend who have a Nikon D70 with kit lenses. Because he is familiar with the system and that his father has a hudge collection of Nikon glass, he wants to stay in a Nikon setup while upgrading.
I have been pushing him to keep APSC as, knowing him, the bulk of a full D700 system will discourage him of carrying it around.
As he wanted also to run video, I suggested him to buy a D300s systems, (with the Nikon 17-55 / 2.8 and the Sigma 50-150 /2.8) the overal cost was about : 3730.33 €. On the same online shop, the K7 with the 16-50 / 2.8 and the 50-135 / 2.8 was 3 096.59 €.
That makes 20 % difference, but it would be even more if Nikon had anything close to the 50-135 / 2.8 (add the 70-200 /2.8 and the price skyrocket, but this is FF glass). I have no doubt that the D300s will produce superior results than the K7 in most situations, but we have to keep in mind that those cameras are meant to be used with hihg end glass. And considering that Pentax is really a bargain.
Additional argument, the K-system is by far the most complete APSC system for high end glass. Nikon does not have a 17-70/4 glass, a 50-135/2.8, a 60-250/4 or the prime lineup.
But Nikon have longer glass, tilt shift lenses, and complete FF lineup, that Pentax haven't.
However, to me APSC and FF sould be considered as different systems even if there are some compatibilities between them.
- FF and APSC require different focal length for the same application.
- FF glass is bigger and heavier than APSC equivalent.
- FF glass is much more expensive most of the time.
From my own experience and some friends who don't shoot in Pentax gear, there is not much difference in image quality taken under low iso and printed up to A2 between FF and APSC. So the decision maker shall be based under :
- Need to shot under low light.
- Need for ver shallow depth of field. (Mind you, I am faced on many cases that my K20D + 31ldt @ 1.8 has too few depth of field)
- Need for very high pixel count, high DR or high iso performance (or a mix)
- Total budget for the system.
Like during the film era a lot of pro were not shooting medium format, today most of them are sticking with APSC, or even are still shooting film.
In France, Pentax is considered a very serious contender for all those reasons. They may not have the best APSC camera (I would say that is the D300/D300s), they may not have the best system for all applications, but they have certainly one of the most consistent APSC lineup (now almost complete but for the lack of TC) and the best quality price ratio.
Currently, if you look at all the models from all the brands starting mid-market, there is no bad camera. What I always say to someone who seek advice from me is : "Go in a shop, asks to hold the camera, pick up the one that you like the most. Picture quality will be much less a result of the camera, than of the actions of the photograher"
I have the budget to move FF, I have a lot of respect for Nikon, Canon, and even Sony, but I stick to Pentax and the lenses I have because I prefer to cary my camera all the time with me with a ltd prime on it and spend my money travelling and shooting.
