Re: Redefining

I downloaded the last 17MB picture and I thought it looked great, but I did not see , at least from this picture, anything special compared to full frame images, for a camera that has a sensor that is 1.7 times larger. Did I miss something?

I was looking at the first shot, haven't looked at the others yet. But I can tell you that one kinda looks like it would blow my weakling 12MP D700 away when it comes to detail at 100%

But it would be nice to compare say a 5DMII vs 645D shot of the exact same subject just for the heck of it.

Re: Redefining

I was comparing to some 24MB shots from a MarkII, and frankly I could not see what the excitement is about. I believe a lot depends on the lighting, subject exposure, etc. when apples are compared to apples rather than from just a casual indoor shot like this, although I appreciate the posted images.

So, it comes down to resolution. Would you buy a D3x over a D3? Depends on if you want twice the resolution or not.

Some might say a 5d MK2 doesn't add a lot to what the 40d offers if you don't need the resolution or extra f/stop.

Hate to say it but the 645D absolutely wastes the Canon for detail much more than it should given they use the same size pixels. There have been many comparison's against it, and its not even close, for resolution, color/hue and just overall image quality. The Kodak MF sensor is built from the ground up for IQ. Consumers and sports dSLRs must make compromise.

I have many pics from both the Canon 5DII and Pentax 645D, download and take a look. I think you may start to see the difference which is honestly not even close. If you can show me two shots that are show me? These are the same scenes and the 645D is just plain breathtaking, and keeps knocking me out of my chair onto the ground. The Canon 5D compares closer the the Pentax K-7, as both are handicapped consumers sensor dSLRs. By that I mean these sensors from Sony, Canon, Samsung are all using very close to the same technology. The Canon 5DII has the same size pixels as the Pentax yet its not even close why? To get high ISO and fast FPS cost IQ, plain and simple. The 645D does not even have an AA filter. Enough talk have a look, it was posted long ago.

Re: Redefining

Everything, and especially a comment on camera qualities, is of course relative, viking. It is very nice to be able to crop to one's heart's content, doing away with the need to be so meticulous in preparing for the shot in framing, in the dynamic range control etc with a larger format camera. Of course, bigger is better but when other things are also considered, such as features, lenses, usability... it is hard to see the 645D is anything other than a very specialised camera for some types of photography, e.g. portraits. It does have 1.7x sensor size and so has some advantages. However, even in terms of resolution and cropping, it does not seem particularly impressive from images and reports that have been available so far, considering that bigger 1.7x sensor. Yes, it depends on what your needs are.

Hi Doug,

Thanks for pointing out. It wasn't me in that picture, I took the picture and the subject is a friend of mine, a long-time Pentax user whose specs are Pentax branded too. Therefore that coating should be SMC.

Sorry, but it is. Time for new specs!

Re: Redefining

I have seen those images. As I said, the Pentax pic looked great, but the point was that with a 1.7x larger sensor, no AA filter etc, you expected it to be significantly better than a FF and therefore it did not seem to be so exciting then from the picture here. I would wait for a properly conducted test comparing its images with what is achievable with the better FF cameras for a proper opinion. So far, what I have seen did not show me it is any special for what it is, or why it is so exciting, as an MF camera with all the associated inconvenience and limitations.

Re: Redefining

Yes but many say the same about FF over APS-C.

All comes down to your point of view and opinion.

A real change....

....suddenly, people wanting a high rez camera are discussing the Pentax....not a mention of Nikon or Canon is heard.

Nice change....nice photos!

Is that you in the image, Peter?

If so, you need a new coating on your glasses.

That's pretty impressive resolution. How does it do at higher ISOs?

Thanks!

Yes the details are stunning. If I were the owner of the 645D I wouldn't use it for portraits, especially portraits of ladies. I'd be beaten up when they see any imperfections on their skin...

Hi Russ,

No that was not me in the image. I took the picture and the subject is a friend of mine, a long-time Pentax user who's wearing Pentax-branded glasses. So I guess the SMC coating on his glasses need some work.

I haven't tried much high ISO above ISO 400 but the owner of the 645D has. He told me ISO 800 was probably one stop worse than that of the K-7, closer to what the K10D used to deliver.

Re: My first Pentax 645D hands-on image (Full-size image link included!)

Hi Pete!

I was wondering where you'd gone!

Thanks for sharing the shots of the 645D. Everyone's been talking about the huge amount of detail, and that's definitely very impressive, but what also impressed me was the buttery smooth bokeh.

I just have one question - how accurate is the AF? Are the shots you shared typical of what can be achieved? I can imagine that the high resolution places much greater demands on AF accuracy.

Cheers!
