Merv-O, good pics especially last one, great colors and sharpness. One thing, did you add some vignetting to the first picture in post? As I see it's F/2.8, shouldn't be there so intense?

DirkWitten · 12-02-2018, 10:50 AM

STARBURST at F11

This Starburst-Effect is really great, razorsharp and really excellent from aperture F9 and higher.

BOKEH at F1.4

Soft an beautiful Bokeh, a really fast an accurate autofocus fully open at F1.4 - wow - Pentax, that´s really a great lens

Lev:

I did in fact, add a bit of vignetting as I thought the White blooms against the beige/white curtain overwhelmed the white balance a bit and I wanted to make the subject the clear focal point. The 50mm Full frame worked fine in the APS-c mode, but I do notice some distortion/bokeh on the red flower toward the rear of the petals,

I see it at the top of the bouquet...it blurs into the background open the top of the blooms...here's another photo of the same bouquet with an APS-c lens and the detail is a bit different you'd agree (I hope)

Lev · 12-03-2018, 01:19 AM

Difference in details is day and night of course, but to see difference in what you're concerned about is impossible, aperture is different, perspective is different, I guess lighting conditions are also different from first shot. Can you link a full resolution original image?

True....just saying that I like the DOF and the glass designed for the APS-c cameras. anyway....photography is subjective...
