lovely set.

I particularly like the style and processing of the first. Very reminiscent of Frank Sutcliffe in my eyes.

Very nice indeed.

You are more likely to find Vivitar 28mm f2.8 close focus version, as the F2.0 version is still a sought after lens and when they do appear for sale, command a high price, especially the PKA version.

A possible alternative might be the Cosini/Petri 28mm f2.0 lens. Admittedly not quite as close focusing but rated by some, well built and readily available.

Good luck.

Beautiful.

Superb effects. Wonderful set.

Delighted that my post was useful to at least one member.

Grateful thanks for the acknowledgement.

No shame and even less pity! lol...

I've got loads of 135mm lenses but would love to add this to the family. I don't yet have a 40mm and your Voightlander is tugging at my heartstrings. lol... But at the moment FFS, I'm low on ready and available shekels through having indulged myself so much of late... lol

How much more pressure can my lens lust endure??? Another sleepless night I fear

Looking at those photo's though, you can't knock or argue with the quality of this lens. And most certainly not at the price you're selling at.

Stunning examples from a stunning piece of Pentax engineering!

Ohhhh the force is week!!... shame on you LennyBloke!!!

Another aspect worth considering is how powerful your computer is. A number of these photo editing programmes are very resource intensive. That coupled with the relatively large file sizes of some latter day digital cameras can quickly grind your PC to a rapid halt. PC power therefore is an important consideration also when choosing editing software.
