Stopped by the local camera shop a few days ago, not expecting any K-1 bodies to be in inventory, but was pleasantly surprised to find a shipment had arrived that morning. To tell the truth, I hadn't really decided whether I'd buy one in the near future, but with the camera in hand, the outcome was a foregone conclusion.

Here's a photo of my morning grind, taken with a K55/1.8 lens at ISO 100, f11, 2.5 sec and Pixel Shift. Below is a 100% crop of the detail.

Nice one, and your story is an example of why the Ricoh/Pentax team need to get this camera out into as many stores as possible.

And isn't it a lovely bit of kit?

I failed to post this little young Woody I shot this morning in the low light, and he deserves posting!

1/200 handheld @ 500mm ISO 6400 Bigma 50-500



I forgot a squirrel too...but I'm gonna pass on posting him....they get plenty of attention already.

Regards!

Yes. House is correct.

This is getting OT but perspective distortion is a property of distance to subject not FL of lens. So standing in the same spot and changing both sensor and lens for equivalent field if view should give identical perspective.
This is true.

"Great explanation.
It's like somebody took all my lenses away one night and added some mystical element to them."

Nope, sorry, that explanation was all wrong. The mystical element is that the rendering of your lenses is qualitatively very different at and near the outside of the image circles they project. More vignetting, different shape bokeh balls, less resolution, it all adds up to a very different character to the images because that area is largely cropped out on APSC. It has nothing to do with perspective distortion if you are talking about equivalent focal lengths/the same angle of view. Of course the fact that wides are wide again is a big difference, but that's not what was being discussed here.

You can trust house on this one, he is the only one in this thread who understands perspective distortion with respect to sensor size/focal length. It's exclusively a function of angle of view and has nothing to do with focal length. There is a simple way to test this. Put a zoom lens on your camera mounted to a tripod. Snap a photo at the widest setting. Now zoom in (to a different focal length!) and snap another photo. On your computer, crop the wide angle shot to match the framing of the optcially zoomed shot. You will then have two shots with identical perspective distortion, because focal length does not affect perspective distortion one bit. Alternatively, put a K1 with an FA 43 on a tripod and take a shot. Now mount the FA 31 and take a shot. Crop the FA 31 shot to the framing of the FA 43 shot. Exact same perspective. No difference. Or mount the FA 43 to a K1 and the FA 31 to a K3. Crop the FA 31 shot (the FA 43 on FF will be just slightly wider than the FA31 on APSC) to match the FA 43 on the K1 and you will have the exact same perspective. No difference. Feel free to test this at home.

K-1 with macro extension panagor

Same photo's I shot yesterday out of the hand with old Pentax smc 50 mm 1,7 and panagor extension rings. This are all crops. First two iso 200 and the third iso not pixel on pixel of the original photo's800 (). The fourth one is a pixel on pixel crop of a iso 200 photo. The fifth is the original phot of the fourth.

Don't you just love Pentax's SR capability. I can't remember ever having been able returning keepers with such consistency at lowish shutter speeds and 200mm let alone 500mm.

Creeping phlox. I had promised on a different thread to test the 16~85 on a K1 in FF mode - it vignettes unacceptably (no surprise) It's really dismal this morning, heavy overcast with a little spattery drizzle which made for really dull images for the test, but I did some PP on this one and got an OK image.

Yes, once I saw House's explanation it was obvious he was right.
I think the difference to my lenses also has a lot to do with the fact that the DOF is thinner in relation to the vertical FOV due to the increased capture size.

What ever it is, I'm lovin it!

Yes, the K1 is simply amazing in so many ways. It brings so much joy back to my shooting!....and processing, the processing is so much easier with the K1.

How good is SR?

1/40 handheld @ 500mm


Combine that with the fantastic high ISO abilities and you have on heck of a great camera!

1/160 handheld f6.3 @ 500mm ISO 12,800..This is not a good example, because squirrels are always handsome with any camera!


Best Regards!
