Just to let everyone know I ended up buying a 50-135mm DA* as per the above post.

I couldn't really afford it so I am having to sell my beloved GX20 to cover part of it (see classifieds.)

I was tempted with ltd but I need a zoom lens ideally as I will use this in the studio on glamour shoots and don't really want to be marching back and forth to go between head shots, full length shots etc.

Thanks all for your advice.

I am selling my spare body as I overindulged today by buying a lens that I couldn't really afford.

It comes with the kit lens 18-55mm and is in perfect condition, not a scratch and has had relatively light use.

If the filenames are relevant to shutter count it's done slightly over 8000

Open to sensible offers.

Can you send me your number please.

Would love it.

Considering selling my spare body to get some of the money for it (Samsung GX20)

Do you know anyone after a GX20? (K20D)

Thank you.

This was using the pop up flash by the way.

I seem to have found yet another problem with my K5 today.

Tomorrow I am doing a portrait where I need a catch light in the eyes of the model even though her face will be in the shade.

I was doing a test just now sat in my kitchen and set my flash compensation to -2.0 and took a shot, I then set it to 0 and then to +1, all the shots were identically exposed.

The camera was on manual mode at F7.1, 160th second and ISO 80.

Just in case I was going around the bend I did the same with my GX20 and it worked as it should.

Can anyone with a K5 please do this test for me to see if it's just mine or a common fault? If this is yet another fault on the K5 and not some daft user error it's going back for a refund.

In fact Dave, having just had quick Google there seems to be a lot of people raving about this lens and they go for peanuts too.

Thanks Dave, I'll take a look.

Thanks Don - so is that what it's called - Pentax AF 1.7 teleconverter?

Is that how I'd find it on eBay?
