I am trying to decide whether I should upgrade to K1 or stay with APS-C cameras and would greatly appreciate your input and experiences about the matter (and I think that it might help me to write my reasoning down).
At the moment I have a 3 year old K5IIs, it’s a great camera but sometimes I wish that it would have a better high ISO, dynamic range and a bit more megapixels.
I prefer wide/ normal angle over telephoto. I mostly photograph landscapes and casual portraits.
At the moment I have a 31mm ltd, 50mm Makro-Planar, DFA 100mm WR and 16-85mm. Most of these would work just fine on K1 and I was planning of using 16-85mm on crop-mode (still would get the same sensor size as on K5IIs) until I can sell it and get a 28-105mm.
Size is fairly important for me since I mostly enjoy photographing while hiking and traveling. But K1 is “only” 250g heavier than K5IIs and 28-105mm is actually lighter than 16-85mm. So my FF kit would not be that much heavier than my old kit, though it would cover slightly smaller field of view.
I would probably need to buy a small 20mm lens at some point to cover that end. I would not buy any heavy full frame telephoto lenses. But if I would at some point need more reach I could just grab a 55-300mm PLM and use it in crop mode.
I was also considering waiting for K3III since it would probably have a great sensor but I feel like with not that much more money I would get quite a bit more with K1 and would not lose that much. Since I am not into telephoto stuff (at least not at the moment). Though it would be sad to lose my 16-85mm, I really enjoy that lens. Is DFA 28-105mm as good?
I am mostly worried about covering the 20-24mm focal length which seems to be easier to do (small and not super expensive) on APS-C than on K1 (at least at the moment). But I am also quite excited about trying my current lenses on FF and about extra control over DOF.
Sorry about quite messy post but hopefully you can follow my train of thought.
If you have any comments I would be happy to hear them!
From your plan, basically if you get K1, you'll get bigger/heavier body, lot of money spent. When chooting the 16-85, you'll not take any benefit of K1 vs say a KP. Your prime lenses would become wider suddently. The 50mm would replace the 31, the 31 would frame like a 21 and you'd get less effective reach for macro with the 100WR while if you used it for portrait or any reach, you'd have to crop.
The day you replace the 16-85 with a 28-105, you'll loose a lot in term of framing. Not as wide, not the same reach. The 24-135 zoom that would be necessary doesn't exist, at least yet. Worse the 28-105 + K1 combo is know to have issues with shutter shake at the most common shutter speeds arround 1/100s...
For the price of the K1 you could just buy a KP + a 17-50 and still have money in the bank and get better high iso with it than with K1 at least when using the zoom. You could start with the 17-50 alone. The sigma is measured as one of the sharpest lenses in K-mount APSC... Doesn't look like a bd deal.
When using the primes, if you don't manage right now great high iso performance, you'll not manage it with the K1. The K1 give you 1.1EV and less dof, not 4-5EV closed down. A fast zoom give you 2EV. Learning to process raw for high isos give you easily 2EV too... And at any apperture for that last one.
It is quite possible to manage high iso with an APSC body. See pictures below...
FA77 f/2.5, K3, iso 8000
F135, f/2.8, K3, iso 800
FA31, f/2.8, K3, iso 1600, pushed 1EV (equiv iso 3200)
DA15, f/4, K3, iso 3200
DA15, f/4, K3, iso 6400
K1 or KP withj fast prime/zoom would do as well or better. K1 or KP with a slow zoom, would do worse.
