UPGRADING TO FULL FRAME

User_removed · 2017-07-27T11:57:34+0100

Hi, I am toying with the idea of upgrading my kit to FF with the K-1. I currently have a K-3 with 3 Sigma lenses f3.5 10-20, f2.8 17-70 and APO 70-300. As far as I can make out the lenses I have would be pretty useless on the K-1. If I have it correct they would knock the effective size of the sensor in the K-1 down to around 18mp, way below the K-3. To upgrade with the FF lenses the problem seems to be that these are few, and far between currently. Plus are super expensive compared to the APS-C models. Also given that my current set up at 300mm is the equivalent of 450 on the 35mm (FF), to get the same zoom on a FF system I would have to buy a lens that goes to 450mm. The other option is to wait for the imminent? release of the K-3iis? and see if it has the same pixel shift system from the K-1 on board + other goodies. Am I looking at this correctly or am I miles off target? Can anyone out there help me out please. Thanks. Andrew G.

I went full frame with the K1 from a K3 (kept a K3ii) not that I needed to, but wanted to and could do.

Was it worth it? sometime yes, sometimes no - yes for landscape and studio work - definately no for everything else (my K3ii has since been replaced with another marquee).

Cheers

K-1 and KP here.

I thought I was done with APS-C when I sold my K-3. Now it turns out that APS-C really has a lot to offer. When you can't be bothered hauling a heavy bag for every single outing, you realise the importance of the crop sensor. The KP really is something else. It's not as bulky as the K-3 but offers quite a bit more (in many ways). It's definitely worth a look if you're wanting a great sensor and camera but none of the weight to go with it.

All the gear with no idea

I do agree and for a camera to carry all the time, the K-1 isn't really it. For me it's a toss up between the MX-1 and the K-S1 with just the 16-85. I'm quite amazed at the quality I get with both.

The comparative compactness of APS-C still has a lot going for it in many ways - not least the fact that I would really miss my fab 20-40 as a walk-around if I changed formats.

I can only agree with the wise words in the previous three posts, I'm glad I kept an APS-C body when I tried 36Mp fullframe a few years back. For all the positive qualities, it's just too heavy and bulky to just 'walk-around' with. Without having a particular project or subject in mind the big cam got left behind, and the K5 (now K-S2) does the job.

I suppose to those who usually carry a 645D or 645Z with a selection of lenses the K-1 is a lightweight camera!
