Hi Andy, I checked out the 18-135 but to be honest it seems to get slated a bit for image quality. Also - I am not looking for a walk around lens as you put it, it's purely for portraiture.

Earlier this year I had all my camera equipment stolen and this included a brand new K5 iiS body and also my beloved Pentax 50-135mm f2.8

I have been unable to afford to replace it and it has taken me this long to get a replacement body - a K5.

Unfortunately it will be a while before I can afford another 50-135mm (which I bought via the classifieds forum on here,) and I am looking to what alternatives there are that are significantly cheaper.

My main line of work is portraiture and it is a portrait lens that I need. I am not into using primes as they slow me down too much, but I would welcome suggestions about any other alternatives.

I have a Vivitar 70-210mm that I am going to try, it was one of the only lenses that wasn't stolen. But I would prefer if possible something automatic.

Any suggestions? I am not too fussed about the 2.8 apperture as I rarely shot wide open anyway.

Quick question - do the lenses have a built in serial number like the camera does? It is going to be hard for me to identify otherwise.

I have the serial of the camera.

Thanks guys, I am hoping it is covered on my house insurance.

I can be contacted on (telephone number removed)

I had my one month old K5ii stolen on Saturday. It is in a black camera bag with a Pentax 50-135mm f2.8, a Tamron 17-50mm f2.8, Tamron 10-24mm, Pentax 50mm f1.4 and various other bits and bats.

Stolen from Dewsbury, West Yorkshire.

If anyone sees anything suspicious I would be grateful for any info.

I don't know what you mean. Yes it's definitely for the K5.

OK I have tried all of the above. I upgraded to firmware 1.15 from 1.03 and did all the other things and the problem still exists.

Also another problem happened today - I took a photo and after it took it the camera locked and there was a faint whirring noise from inside. I had to remove the battery to get it to work again.

Worried.

I have one of these (that I bought on here) but my mate is jealous and wants one too - has anyone got one for sale for around the £500 mark?
