I don't want to beat anyone up, but I have had no such problems, and have found no conditions to date where my particular K5 has not performed to my satisfaction. For those with problems, and I don't question their honesty, I hope you can get a resolution either through a new body or service. It troubles me that someone might be missing the satisfaction I am enjoying with this fine camera.
When the FF issue appeared to sour my desire for the K5, I was at the edge of buying a D700....and every day I thank my Lucky Stars I didn't. For those that live by shallow DOF, the D700 would be a good choice, no doubt, but for the vast majority of shooters, I think the K5 beats it easily. Considering the ISO abilities of the K5, the price, and the fact that you don't need a forklift to haul it around, the great IQ, and the efficient ergonomics of the K5, it is no wonder I thank those Lucky Stars!
Best Regards

Hm . . . . I am not understanding this correctly. Zeiss T* 50/1.4 is manual focus only.
Oops, I meant my Pentax F/1.9 43mm lens. Sorry. That's the one I was comparing. At any rate, most of the focusing behavior I was concerned with was also a factor with almost any indoor available light situation.

Well, D700 is a special camera. Except for the size/weight (and price), there is no disadvantage to owning a D700 over k5. Focusing is in a whole different league - both the speed as well as accuracy (and tracking). And even though k-5 has improved high ISO, 700 has (still) cleaner high ISO. I love that camera. I think that is one camera that doesn't require any upgrade for any reason...Everyone who likes photography should use D700, at least for some time


cheers,

Abhi

I don't doubt what you say, but the size/weight thing, of both the camera and the lenses, would be a deal-breaker for me. That and the fact that Nikons feel "icky" when I hold them.

Actually in a lot of lighting levels and scenes narrow DOF is the way we actually see things with our own eyes and probably accounts for why it we find it pleasurable or natural.

You don't normally notice it becuase you are concentrating on the subject and your eyes AF as you flick from subject to subject at different distances.

This isn't exactly accurate; at normal distances, our eyes have pretty high DOF ( They also have terrible resolution ). Hold your thumb out at arms length and focus on it, closing one eye. You'll notice that that the background is OOF, but not so much that you can't easily identify objects - certainly nothing like the blown bokeh of a 1.2 or 1.4 focussed this closely. Outside in sunshine, when your eyes stop down, you'll notice that most everything is in focus.

But we've got a binocular vision system and an image processor that sucks every bit of detail it can out of the environment, and puts it in a "map" in our visual cortex. Because of the way we process objects, we "see" them as distinct from one another, sharply delineated. The low-DOF is the closest that a flat, 2-D image can come to replicating this 3-d+processing isolation that happens in our heads.

I was out today with a 2.8 in low light, sunny day but under the canopy, and the Af only hit 3 times out of 20. I will see if i deleted the photos or not. If not i will post and add a link. Funny the 300mm 2.8 lens will AF all over the place. But the same setting the 500mm 4.5 is spot on. I was going to do some tests today but was to busy. As much as i hate too I agree with Croc.
It is a problem with where it focuses for sure. The larger DOF saves the shots with 4.5 and above but f 2.8 is just useless. At first i thought the same thing. Sigma is the pits, but with the 300 in the service center again. I have to throw up my hands and move on to cannon.. What a shame.

I've been critical about testing. but this is getting just funny how bad Pentax is. For me only I have no choice. It is either switch or not post quality photos.

I've said it before but again. I will not buy another Pentax lens. But will pray for a good camera.
Um... I'm not sure what you're shooting, but at the same operating distance, your 500 f4.5 should have very similar DOF to your 300 f2.8.

Not sure if the OP is just having problems with very wide apertures, but I have hundreds of shots like this taken with the K20D and the K5 using the DA*200 at f/2.8. I've always been impressed with it for action shots. I was assuming the OP's problem was with apertures wider than f/2.8.

You can go to my Flickr site and see the original size if you want. I just haven't experienced the problems the OP has.

I hope your wrong..as I want one ..im hoping the D700 replacement that will have a 20Meg something sensor will get the up-graders all sweaty and twitchy ..that way I can swoop in and get a decent used D700 for peanuts...least thats my theory for now ..LMAO....mind you id like a D800 with a 21Meg sensor too

Well that was a fun read

A bit topsy turvy example all my lens are calibrated in daylight and then predominately shot in mixed Sodium/Fluorescent and daylight.

I don't have any issue like the OP states

I can't agree less......It is like saying everyone that loves women should try a fat wife......except for the size, the weight and the price of food.

I have a friend that has two D700's and a D3X, and I have used them, and they are excellent, but not as good as my K5 for what I do. If I did all studio work as he does, I might consider you having a valid argument, but I need a smaller lighter camera, and I need the crop factor that the K5 provides along with the higher resolution, since I am a habitual cropper. I can crop my K5 images and still have tons of pixels to work with....that matters to my subjects and shooting needs. Size and weight matter......if you have to use a forklift to take you wife dancing....you don't go dancing all that often. Same with big cameras. I may be biased, Mrs Rupert weighed 118 lbs when I married her 45 years ago, weighs the same today......a fat wife has never tempted me, neither has a fat camera, although I admit the 645D might catch my eye!

Best Regards!

Well considering that I can get two!! K-5s for the price of one D700, I would expect the D700 to have a few more features. But even tho it is twice the price of a K-5 it is NOT twice the camera. And...I can't use my 43mm f1.9 on it either.

Eruditass,

Those pics you posted are great. Not sure if I got your grammer correct. You meant that you used the Brenzier method for those pictures which gave much shallower DOF than one photo at 1.4 could give, correct? Thanks for posting, I never heard this term before, and looked it up quickly. So, the summary of the method is, if you want a wide shot with shallow DOF, since DOF is shallower at longer focal lengths, use a longer focal length lens and take multiple shots, and stitch them together to get the wider perspective but take advantage of the shallow DOF?
Those photos were created (by others) with the Brenzier method, which is simply being closer than you would normally be standing, and stitching together shots. The closer you are, the shallower depth of field, but of course you won't get everything in frame. Yes, it is shallower than one photo at f1.4 at a normal framing distance.

You typically use a telephoto because it is easier to stitch together, as when you get closer, the camera is more sensitive to rotations that are not around the no-parallax point.
