Re: why am I looking to get back into Pentax.

I do a TON of DSLR scanning. A lot a lot. I've long been wanting a K-1 to get around bayer type sensors for scanning.
That's an interesting point. Why DSLR scanning with Pentax K-1 is so special (vs Nikon). May you elaborate a little?

Pixel Shift scans each pixel individually four times and makes a composite image with a true reading of colours, and which also reduces noise. Four exposures, red blue green and luminosity. A bayer sensor scans once and guesses by averaging the colour values in two of the 3 colours in each pixel. A foveon sensor reads all three colours during the same exposure, by reading different colours at different depths in the sensor wafer.

OK. Back on topic.

First, the OP needs to be aware that the DA* 55/1.4 is not totally full frame compatible. In some circumstances the image circle doesn't quite make it to the corners of the frame. The image quality is really nice though - I think it's an even better lens on the K-1 than it is on crop.

Some portrait-ish shots. All very informal.

f/4.0



Hand held selfie @ f/2.0 - no easy task with this rig



f/1.4



Low light action

Here's a a random portrait of my child with the 55 at 1.6 it says. Not sure of the quality but hopefully it gives you an idea. I probably have more but not on my phone which I'm currently on.

Damn those samples are looking great! I love the bokeh in that portrait by 'paolojackson'.

This lens is going to rock.

I've been impressed with the lens especially on FF. It's actually become my favorite lens and I never shot at 50mm on FF. Had a Canon 5d2 and shot 35/85/135.

It's pretty sharp wide open, very sharp by f2. Fairly compact lens and can be had for $350 or less.

Don't get me wrong, if I had the money I'd go for the DFA* 50 but there are a lot of good things going for the DA* 55 and it suits my needs perfectly.

The bokeh on the DFA 50 1.4 is a teeny tiny little bit better in some images, but for folks like myself, not enough to make up for the difference in cost and weight.









I don't know how lived so long without it.

I don't have many photos that are portraits with really narrow depth of field, but here are a few that might be helpful.

I knew you had portraits. I spent an age last night trying to find some to link to.

A very pretty lens, whatever it does the DFA*50 will do better, of course, @Sperdynamite :
