Upgrade to K5IIs from K5 now or wait for something better?

Looks a different beast to me. 645D is medium format, while the D800 is a FF DSLR.

645D seems specialist to studio type work with a limited ISO range while the D800, is well a high end FF DSLR for a wider range of uses with a higher ISO.

Well according to DXO the 645d is just 500 pixels wider sensor than the D800e

On the other forum one of our countymen insists that the problem lies with the lenses rather than the camera body.

Can you be more specific? Maybe a link? My 50-135 is faster and more accurate on my K5II vs. my K20D, so from my perspective it's body not lens, although I concede the 50-135 is a sluggard compared to other SDM lenses.

Actually it shows the horizontal pixels of both is 7424, but resolution isn't everything. The pixel pitch is significantly different.

Sensor IQ is not governed purely by the number of pixels, so 500 here or there makes little difference. What does make a huge difference is the size of each pixel and the spacing between them.

I don't agree on the landscapes comment though, infact I think entirely the opposite..for me Pentax bodies and their lens line-up seem more designed with the landscape photographer in mind...excellent dynamic range of the K5, weather proofing, solid build, plenty of wide angle lenses.

Simon

Simon, I think i might have been unclear in my comment..... I did not mean to say that a different camera than the K-5 is needed, rather then different cameras have different strengths, so a camera which is great as sports (say the Canon 7D) is not best for landscapes (where the K-5 excels). The Nikon D800 is probably good at both, but it's in another league.

I think your work is there to prove the quality of the K-5.....

But still, an improved Pentax camera with a FF sensor might even be better at landscapes....

Just done some videos comparing the speed and accuracy between the k-5 mki and mkii with the DA* 50-135mm attached. The focussing accuracy was interesting in that the mkii locks straight on and the mki hunts very slightly, but you can hear it focus to far and then step back.
Obviously this is in daylight so will be more pronounced as the light lowers.
Speed wise I think a difference can be seen.

First mkii speed

mki speed

Accuracy first mki

then mkii

To Smeggy,

I may well upgrade now unless I think better of it over the weekend. I have reached an age at which there is a lot to be said for enjoying new thngs now rather than putting them off. If a new 'all singing and all dancing' model is announced, I do not think it will be before late summer or autumn and it will not be available for some time after that. If I were to decide to go for that, I think that I might keep the K5IIs as a second body rather than trading it in.

This is the link to the DPR discussion. I have to admit that I had just returned from the Wetlife Reserve at Arundel and had been using my 55-300, so the poster who mentioned lenses ( awaldram) has a point in that there are better lenses for birding. I am not really a birder otherwise I might have acquired the Sigma 150-500, but I feel that I would not make very much use of it and I really do not like heavy lenses much anyway. My comments on AF, however, really apply across the board to other lenses too.

The sensor is only a part of the overall ethos of the camera anyway. The 645D and D800 are totally different beasts.

but, if we are comparing MPs, the nthe 645D is ancient in comparison to the D800 ( and my Nokia 808 phone )

I'm sure if Pentax released a medium format camaera now it would probably have 60MP or more

I agree Smeggy, but who would have thought when the 645d came out an FF sensor would have been launched with a pixel density that size? I think any new medium format body would have to have at least 80 megapixels just to keep ahead of the FF pack...

I often see it said that FF and medium format cameras are good for landscapes but isn't a downside of them the shallow depth of field?

For landscape shots you often want a deep depth of field. On a large format camera doesn't this mean either stopping down beyond the lens's sweet spot, or taking several shots at different focus distances and atempt to combine them post process (not that simple as image geometry varies slightly with focus distance)? It's hardly ideal.

It is true that large format landscapes do tend to have a different look to them but I put that down as much to the skill of and care taken by the photographer as much as a difference in format. It would take be a brave man to criticise some of the classic large format landscape shots and claime a different perspective/depth of field would have improved them.

But it may come first in FF or APSC rather than medium format. Unless the MF demand is sufficient to warrant developing a new state of the art chip at the right time.
