FULL FRAME OR APS-C

It really depends on what you want. The K1 will give you better image quality, a bigger VF and the originally-intended field of view of older lenses. You pay for that in size, weight and burst rate plus size, weight and cost of lenses to go with it.

Personally, I love my K-3 and would love to get a K-3 III if it ever becomes available at a reasonable cost (not guaranteed with the current market). I have all of the DA Limiteds and many other APS-C lenses which I couldn't replace on FF, either because they simply don't exist or because I wouldn't be able to afford them. These days with kids, a smaller kit is advantageous too and I suspect there would be too many situations where I would leave a K-1 behind and take my much smaller and lighter Fujifilm kit.

The K-3 III will almost certainly have the 26MP sensor that's in most modern APS-C cameras and it's been shown to be superb.

It's all down to what you prioritise.

This is just exactly my thoughts as well.

There is a significant difference in specialties between the K-1 and the K-3. The K-3 is a very capable fast camera and the K-1 a slower but incredibly detailed and capable camera with a different objective.

I don't really subscribe to the marketing focus on sensor size anymore, as there are very capable cameras all the way up to the now quite old 645Z.
You really do need to start with your requirements and priorities, and then chose a tool from there.

Thanks to all regarding this topic. As you will have guessed I am just an amateur photographer and can't imagine me needing to print "poster size" pictures. I have a number of pictures of my own work on the walls in my house, requested by the wife I hasten to add. These are a max size of approx 20" x 12" and this is way big enough.
If I had to choose one area of photography to concentrate on it would be landscape and from what I read a FF is best for this type of work. Hence my question. It does seem though that an APS-C sensor has all the attributes I need. I was starting to examine the possibility of upgrading to the K3-lll but the indicated cost of the new one is too close to, if not more expensive than, a K1-ll, not to consider the FF. I really don't feel like paying out around 2000 for an APS-C. I love my K3-ll and it has given me some great photos (to my mind) so will probably keep with it and see how the K3-lll develops, if it's ever released. I do, though, really like and use the GPS on my current camera and the upgrade, as far as I can tell, does not have this facility for some reason. I find that this is a brilliant and very useful bit of tech. I never used the pop up flash much so that was no loss to me.
I will stick with what I have for the foreseeable future. Thanks again to one and all for your input.

I'm an old film shooter and bought my K-1 primarily to use my wide-angles as they were intended. I didn't have many DA lenses (I need aperture rings for my film cameras). When the K-1 development was announced I bought a few FA lenses to be ready for it. Things like better IQ, dynamic range etc. are merely details, the single biggest reason was an FF body for my FA43...

I don't need fast AF, burst rates and a host of other features, but I did want the FF format. The built in GPS saved me buying the separate module and extra features over my K-5 are amazing. The K-5 was too small to grip comfortably and I needed the grip most of the time. I bought the K-1 grip, but for me the camera is better without it - and similar in size/weight to my gripped K-5. I kept the K-5 as it has a very low shutter count, it was hardly worth anything and is a good second camera taking the same batteries/chargers etc.

For landscape using a tripod many of the advantages of FF over APS-C can be drastically reduced. Using a tripod would allow the use of a super-resolution mode which typically quadruples the resolution by shifting the sensor. It would also allow HDR photos. These two things give gains on resolution and dynamic range, the two areas where FF is advantageous in landscape photography. Of course those two things can be done with FF too but how much is enough? Is 96MP not enough for a landscape photo?

I too am looking at K1 v APSC, and wonder what the image quality of the APSC cropped mode is like on the K1 vs. K3ii?

I don't use the crop mode on the K1but do crop heavily sometimes,

Very heavy crop from a K1 + Pentax 150 - 450 lens ISO 1600




Small crop K3ii + Sigma 100 - 300 Lens ISO 100

I have used crop mode on occasions purely because you get faster fps and the buffer doesn't fill as fast but most of the time I leave the K-1 in FF mode and crop as required. If you do this when using a crop lens you can normally get a little extra out of the picture if required.

Quality wise if you put a K-3 image against a K-1 image which has been cropped it would be hard to tell the difference apart from the K-1 file being smaller.

I have said I won't be buying the K-3 III (and have actually written out a sale ad for here listing my K-1 and lenses) but I am quite interested to see how the AF performs on the new camera before I go ahead.

What do you do with your pictures ? Print/post to web ?

I just put them on my home NAS.

Question is driven by my heavy investment in DA lenses and no intention to buy any FF ones.
