Originally posted by nkull Norm, you seem to have a big beef with the D750 specifically and I cant figure out why ... I’m not sure where you get this idea that it tries to be something in between a APSC and FF camera, it is not a “FF Type camera”... It is a full frame camera, period, and it does full frame camera stuff very well.
Not true, what got me into the K-1 is the difference between the K-5 and K-3 and a D800/D810. The D750 doesn't do that thing. I want to see the detail in the reds on the IR clothes swatches as linked to above. The K-1 does them just fine, the D750 doesn't do them at all. An A9 does 24 MP and 22 FPS, a 1Dx does 22 and 15... For me the two things I want from an FF are more resolution or better low light and higher frame rate. That what would make up for the loss of resolution in the crop area, and needing longer lenses to get the same FoV.
K-3 and Tamron SP AF 300 2.8 LD [IF] and HD DA 1.4 TC, 420mm ƒ4.
400 ISO, ƒ8, AV
O.K. then, I went out for a bit today, the roof is totally off my blind and it's completely ineffective... I did manage a few shots.
A D750 on the above image would cost me 70% of my resolution. A K-3 puts 24 MP into the same area a D750 puts twelve, and yes, these are cropped images, so it matters. The D750 just doesn't do anything I want a camera to do. As I said, a good general purpose kind of camera but I really don't do a lot of "general camera" type stuff., but distinct disadvantages compared to both a K-3 and K-1. It has some advantages too, like 51,200 ISO images, which I really don't care about, and better AF. But on the above image, Pentax AF is more than adequate. Faster tracking AF would have no advantages, and besides, Pentax AF when not tracking is really fast, with a fast focusing lens.
For me, a K-3 is better than a D750 at what I'd want to use it for. A K-1 is in a different league altogether. It's not just the D750, it's the A7, the 6D are the same type of camera. When there are 24 MP APS_c sensors, it's kind of hard for me to understand why 24 MP FF is even a thing.
I have nothing against a D750, if given one I'd sell it and put the money towards something more specialized.
You tell me where a D750 would fit in. The K-3 is better for wildlife/birds etc where the extended reach is valuable, the K-1 is better for low light and resolution, the D750's only advantage is tracking AF. What do you see, I'm not seeing what makes you feel this is more than an average kind of camera? It's pretty good in a average camera kind of way.
