The A 50mm f1.7 is a great lens - I have one in similar condition that I love using as it's tiny, sharp, and fast. The plastic aperture ring isn't nice, but with a DSLR you simply set it to A and don't touch it again. The focussing feels much nicer than a modern AF lens, with far more feel.

Price is a tricky one. I paid £42 for mine a couple of months ago but prices seem to have gone a bit mad of late and I did have the advantage of spotting a listing that was simply titled "Pentax 50mm". I saw a fungus-infested example hit £36 around xmas, which is utterly insane money for a less-than-perfect example. I don't think you paid much over the odds however, from looking at other listings.

Do you think this is a manual focus or is auto ???

It's manual focus but auto aperture - just set the lens to A and switch your camera to manual focus.

Here are a couple of shots I took with mine:







It's not a wide angle lens but this can be helpful as it crops out unwanted foreground distractions.

It's a great lens, I'm just not sure how suited it is to weddings. I've never been especially interested in portrait photos, as I like driving out into the hills in search of landscapes (and some of the most entertaining roads on the planet ).

on istDS it'll be equivalent to a 75mm - a nice length for portraits, and the fast aperture will help for that too.

A 50mm lens is always a 50mm lens. On Pentax digital, it gives the same field of view as a 75mm lens on a film camera, but what have film cameras got to do with it if you don't use one?

You know what 50mm is like from experience with your 18-55mm lens.

Enjoy it anyway. You chose a very good model, and the price is about the going rate these days. They were going for only £25 or so a couple of years ago, but they've got a lot more popular as more new DSLR users discover them.

Having just purchased one of these lenses, I find this topic very interesting.

I do struggle with manual focusing (tired old eyes ). I am thinking of either a split focus screen and/or a magnifying eyepiece.

Has anybody any suggestions, (yes I have seen the other comments about Katz eye)Just asking for advice.

I use a magnifying eyecup on my K7 and I find it is easier to focus with than the 'standard' viewfinder. Have not tried a split focus screen as far as I know My first SLR camera ever was a Praktica BMS which had a strange viewfinder with some concentric rings and parallel bars in it which all lined up properly when the object under view was in focus - I dug it out the other day and had a bit of a play but think I prefer the standard viewfinder with magnifying eyecup on my pentax. The only drawback is that I find I have to look around a little to see what is in the corners of the field of view, but then I also wear glasses and maybe my eyeball is stood off from the eyecup a little too far. It's not a significant issue for me though.
