Originally posted by rgknief60 Captured these last Wednesday. This was the first outing where I shot primarily with the K-3III because of its higher pixel density. I paired it with the HD 1.4x & 150-450.
Was disappointed as I never got any detail in the individual feathers, even with this relatively close shot. Am I expecting too much?
It seems to me that the K-3III is far behind the K-1 in ISO performance, and I'm wondering if I should have shot them with the K-1 and cropped out the vignetting...
Any suggestions welcome. Thanks.
F8, ISO 1000, 1000/sec.
Sandhill Cranes Your image does not enlarge much in Flickr, maybe because of your Flickr settings, or maybe because the image is heavily cropped, so "pixel-peeping" isn't possible. You don't say whether the image is hand-held or on mono or tripod, or even how far away you were from the subjects. Without this info, and not being able to magnify much in Flickr we can only guess.
My money is on the use of the converter. I have had OK results with my K3 3, 150-450mm, Pentax 1.4x Converter, and some mediocre results, even when using a tripod. Lightiing levels might explain the difference.
But I don't think shooting at ISO 1000 on the K3 is even remotely part of the problem (
UNLESS there is something about the converter which degrades high ISO images???)
Take a look at this shot of mine with the K3 3, 150-450mm but
no converter (ISO 5000, F9, 1/1000s):

While the K1 no doubt does have better low-light performance over most other earlier Pentax models, I think that difference is probably at its least noticeable when compared to the K3 3.
I would be most interested to see comments from others with morek hardware tech savvy than myself on this.
