Wow Philip,

What you can do with this combo! Great!
 
Thanks Jetse
 
Dear Philip, you've become too famous to this post. If you do not stop in time you might get the Nobel Prize to the BIF ..................with stationary bird . :-)

Hi Barry

This is just testing to get used to especially the DOF. However I always try to frame as tight as possible. For me that is the challenge of bird photography getting as close as possible. The more MP's you can get into the frame the more detail I believe. :-)
Thanks!

I used to think that. I mainly used slide film from the early 1970s to 2004. I framed closely, often too closely.

In the last nearly three weeks, since I received my K-1, I've been re-thinking the balance between resolution and other factors. In the past, I've printed successfully at A3+ with just a fraction of the pixels available in a K-1, and the K-1 has good pixels; I don't need them all in the final photo.

Obviously the bird needs to be covered by at least a certain number of good pixels. But what happens when that lower limit is exceeded? If a photographer is willing to throw away half the pixels of a K-1, what benefits can be achieved in their place? Ease of use? Better AF? Lighter, cheaper, lenses?

For me, one of the benefits of the K-1 is that I can stop trying to frame as tight as possible.
I can stop trying to get ever more MPs into the frame.

Obviously none of that contradicts "the challenge of bird photography getting as close as possible".

Dear Philip, I have a lot of patience.

If I am not moved to Nikon , I have some patience . ;-)

I am deflated a little, when I learned that Sigma lenses have problems with K-1.

I have Sigma 150-500mm and Sigma 70-200mm f2,8 macro II EX , both FF.
Well you could fit them on the HD converter as its only SIgma made the metal mount too big.!

oh wait....

no you can't as Sigma also miss back-engineered the PKaii protocol and they wont AF on the HD converter

Caveat emptor
Very strong strike for me.
Well if you go Nikon or Canon your existing Sigmas wont fit and many older Sigmas like yours will require FW updates to work correctly on newer bodies.

Thats if there still a 'supported' product by Sigma

So if you have a major issues with Sigmas fitting OEM cameras then maybe you need a Sigma body ?

AT least with Pentax it only physical design and APS-c/FF detection the lens actually still work (as much as they ever did)
Is this bee in your bonnet about Sigma going to spread into every conversation you have now?

Hi Barry

What you say make a lot of sense. If you look at the eye of the this bird I am starting to wonder myself how much more can we actually resolve?




Taken with the 150-450 at about 3m

That is a stunning photo!

But I'm not sure how to answer the question. Or even if it has an answer.

Here is something that makes me doubt any attempt to identify robust guidelines. Here is a picture in pride of place in my home. The photo, "Looking Out", is printed on A3 paper, mounted on a white 50cm by 40cm (or 20" by 16") card, and framed.

"Looking Out".
"Looking Out".

The image is a crop from a photo I took with the Pentax *istD in 2005. The size of the crop is shown below:

Original of "Looking Out".

I used two-thirds of a megapixel from the *istD to print at A3 for one of my favourite photos hanging in my house!

It scored 20 out of 20 in a club print competition, and helped me become "Print Worker of the Year" and "Club Worker of the Year" in 2006/2007:

I like pixels! Lots of them. With 18 million of them I can do all sorts of things. So I really like to use half of the sensor of the K-1. Although for publishing on the web after downsizing, using just a quarter of it may be enough.

The K-1, with 36 million good pixels, is challenging a lot of my assumptions. They make it sound like a landscape or studio camera. But if I'm prepared to sacrifice half or more of the pixels, I can use more relaxed composing and reduce the demands on the AF system for action shots.

I'm making things up as I go along. I might give a different answer to your question in a year!

You have very nice birds that sit still and pose for you :)

EDIT:

Image 1, 2 and 3 are a bit special.

The birds are all siting on a stick. And I think 1 and 3 on the same stick.

I have a guess. You have a stick somewhere in the middle of a field. Birds like to sit there and look out over the field. So, you have a camera mounted and focused on the stick.

I don't think that a subject as relatively small scale and simple as a bird needs the 36mp of the K1. Those 36mp wíll prove their value in e.g. wide angle landscapes with lots of trees and tons of other detail, as well as a wide dynamic range.

Using the K1 in crop mode will make most sense, and then you essentially have a K5IIs, with sufficient room to crop. To me, the K1 would make sense because it can double as a stellar landscape camera with wide angle primes, and a no doubt very good birding camera with a 16mp sensor like the K5IIs (or better). I use the K3, but I did actually feel that the 16mp K5IIs was a better choice for bird photography. The only reason for getting the K3 was the upgraded (screw drive) AF, and actually I had plans more than once to get a K5IIs again. I will get the k1 in time to replace the 24mp K3 (unless it is itself replaced by a 16-18mp apsc camera with upgraded SR and AF), and I won't miss the 24mp's of the K3. The most compelling feature for bird photography in the K1 is the new SR. I will use the K1 in crop mode 95% of the time I guess....

I was excited to see you did a post! I love your sharp bird photos.

I was particularly impressed with your White Eye photo, the eye feathers look fantastic.

Here's a crop of the highest res shot of mine:



Have you done a post describing your PP details?

cheers!

I think I agree.

That is where I differ. The problem with Crop Mode it that it is in a fixed position.

By using the whole sensor, I can focus on a subject that may not be at the center of the resultant photo. Then crop in post-processing, but not necessarily in the same position as the K-1's Crop Mode.

But that really applies for a moving subject that I'm trying to get a focus-lock on. I'm not talking about a static bird, where Crop Mode may work well.

I recognise that the frame rate for Crop Mode is specified as 6.5 rather than 4.4.

Hi Chris

Thanks

Nice shot.

As for PP I use Silkypix DS 7 pro. With the K-1 I use default sharpening and usually bump up the contrast by 1. Correct exposure if necessary and then downsize without any sharpening.
