Looks great!

clackers: Actually Sandy's and Rondecs' photos posted here earlier vs Drilling's and yours, clearly stated the difference. Look at the color and transition!

OK, I'll play
A crop from one of my FA77 snaps. Remember this is at f/2.8, while clackers' is at f/5.6
Suffice to say both lenses are pretty good....

Well, if I and Photozone have better results than you, Grahame, whose lens is not up to spec, ours or yours?

I find the microcontrast of the DA50-135 a strength over other lenses, Grahame.

The coatings are more modern for starters.

This is a traditional Pentax plus. Zeiss were one of the first companies to license SMC technology.

I'm confused Which lens are you shooting with?

Well, I posted two with the DA*50-135.

Should I also put one up taken with the wonderful FA 77 Ltd?

Okay, then!

Warm night outside, available light from an advertising sign.

Aren't we Pentaxians lucky to have such fantastic choices?

Since both lenses use the same SMC/ghostless coatings, I doubt the coatings on one lens are really more modern than the coatings on the other. The DA* 50-135 is a zoom designed for APS-C digital. The FA 77 is a prime designed for use with film. Perhaps due to concerns about sensor flare, purple fringing, and the smaller recording medium of APS-C sensors, DA lenses tend to have a bit more contrast and even sharpness compared to FA lenses. The DA lenses are back coated and tend to use more ED glass. The 50-135 uses three ED elements, the FA 77 none. That can have an affect on color contrast, sharpness, CA/fringing control.

Well, that's probably it, Greg.

The DA* series introduced Aero Bright coatings. but I think they ended up in the DA*55 and DA* 60-250.
