When? Why? Full Frame

Curious if some of you folks on here shoot professionally with a crop sensor camera?


When would one need to justify moving to a full frame camera? (Certain type of photography? Certain type/size of pictures...etc)

I shoot a lot of macro product work on a Pentax K5IIs, also I use the 645Z which is a crop sensor camera too. I do use "full frame" cameras from Canon,Nikon, Leica and Phase one - but a majority of my work is on crop.

I will move to K mount Full frame, I have far too many lenses designed for full format that it would be perverse for me not to. But I won't toss out my K5IIs anytime soon*. But to be honest I don't think I'll be using it (the pentax K-1) for commercial work, especially if it has a sensor with a similar pixel count to the D810, which I already use.

*I might even buy a second one as the K5IIs is, especially at low ISOs an excellent camera.

+1 on the K-5IIs. That camera rocks big time.

Shooting professionally does not mean much. For A4 sized photographs (or even web sized photos) like for journals/magazines, a K-5 or K-3 when used correctly deliver more quality then needed. For advertising (A1 type of enlargement) in public areas, it's not that APSC could not do it at all, but it simply can't compete with the quality delivered by other pro photogs who are using full frame and medium format systems. And think about the cost of traveling to a place relative to the cost of a camera system, even a full frame camera depreciated over 5 years costs peanuts compared to the cost of traveling and labor time, so why limit yourself to APSC ?

I will probably be an early adopter, but keep my K5IIs - but will certainly send it for CLA after 2.5 yrs of hard use.

Do all full frame cameras have the ability to shoot in crop mode like the 810 ? If the K1 has this...wouldn't that be the best of both worlds ? Shoot in crop mode for birds/zoom.... full frame for landscape ?

Most do, the K1 definitely will, for use with DA lenses. Though from what I heard it is not a mandatory crop.

Why not just crop in post? No difference.

I think the biggest reasons to go with full frame are if (a) you have a lot lenses that are full frame compatible -- Pentax has a bunch of lenses that fit this and I think folks who own, say the FA limiteds, have been salivating for awhile to shoot them on a larger sensor or, (b) you are pushing the limits of crop frame -- this can be with regard to wanting to have more shallow depth of field, better performance in low light situations, or the ability to print larger. A final benefit is that viewfinder should be bigger and brighter than current APS-C optical viewfinders.

The biggest negatives with full frame are that you need a longer lens to match the same field of view (sure you can crop, but if you do this a lot, why pay for the extra sensor area?), cost is higher (full frame has dropped in cost, but so has APS-C), and frame rates tend to be slower.

You are assuming that one needs a reason to go "full frame"

And as I said, you can just crop in post... like almost every FF wildlife shooter does.

A D810 in crop mode is 15 MP. Which surpasses a K20D but no Pentax product since.

I'm reading the K-7 as 4672 by 3104
D810 crop format 4800 x 3200.

We're getting a little nit picky here are we not?
