Fun with images taken with the Pentax K1

[Michiel Schierbeek]

Michiel:

I understand. I don't use my K-1 often, but PS is worthwhile when possible. Shots below (pre-dawn) are K-1 witn 28-105mm using PS and 645Z with 80-160mm. Z shot has more resolution but the K-1 has much less noise. Approximate same angle of view in both, heavy crops.

Interesting. A bit strange, I see the K-1 picture has ISO 2500 and the 645 only 200. Never ebcounter so much noise @ ISO 200. Probably false information and both shot @ 2500?

It's a mystery to me too. This is the only time I had both cameras and did a test. I am suspecious about the ISO, but my wife had been using the K-1 so it's possible. Note the f stop and exposure time of each image are almost equivalent, despite the high ISO difference, so inaccrate info is possible. I was surpised by the noise too -
no explanation.

I just came across these shots of yours Tom. Is it also possible the K-1 had noise reduction turned on? Again not having worked with the K-1, I am asking this question blindly. Also for whatever reason, its hard to believe the 645Z shot was at ISO 200 (recorded inaccurately)?

IMHO it look like Clarity MAX Structure MAX, Sharpness MAX issue.

The smoother shot has visible motion blur from a much longer exposure. Something is not right, or is merely mislabeled.

Mea culpa, I hadn't looked at these images in some time. I checked the RAW 645 file, that shot is about 3 stops underexposed, hence the noise. The crop posted below is from a properly exposed ISO 200 645 file taken at the same time and it has considerably less noise in the sky, comparable to that in the ISO 2500 PS file; it also suffers from some camera movement. Included is an uncropped image of the overall scene to give a sense of scale.

Some shots with the Samyang TS 24mm lens. Not ideal distortionwise but not to bad after some corrections.

So, am I the only odd duck left? Pentax K1 43FA Limited Hand held 1/6sec @ F/1.9 iso 800. Very minimal contrast and sharpen.

You are not alone. I am still using the K-1. Nothing wrong with the camera.

It's particularly difficult to shelter when you live alone

Yes, it is. Just me beside myself. I thought that it was time to exercise the imagination and the camera!

Looking for Perseid meteors last night, but no luck. I did get an interesting shot using a K-1 with Astro Tracer. Approximately a 5 min. exposure using a Rokinon 14mm. The K-1 is still an amazing camera and I will always prefer an optical finder.

Quentin -
My 35FA f2 is doing fine. But enough about lenses!
The question is about color. Why are your shots radiant an mine so blah??

It has certainly been a colorful fall albeit dry. There are no waterfalls, but the occasional puddle can be interesting. K1 Zeiss Vario-Sonnar 35-70 Leitax adapted

Winter light, using the very compact 40mm.
