looking at Sigma service tarrif it would be around £110 for repair Gareth. had my 17-70 done by them for £95, it is in a lower price band than your 24-70 f2.8. it had the image stabiliser replaced and came back looking like new. was away 3 wweeks .

thanks Sry, must admit the "goldie" look is growing on me having seen a few on the net.

can't change email, keeps reverting back, will not accept K3ii as camera in profile keeps reverting to k70, will not accept lens entered in profile reverts to a 645 lens.

you did indeed Gareth. thanks for comments both.

an old "new toy" that is , Pentax 1st DL IR converted. at our local park yesterday in the sun .

1. Turning a 720 nm filter into a 590 "Goldie" with help from NIK and PS CC. Pentax A 50mm f1.7



2. Usual Red and Blue Channel swap in PS CC, Pentax A 50mm f1.7 lens



3. Black & White processed in NIK Silver Efex . Pentax A 50mm f1.7 lens



4. Another Red/Blue Channel swap. Sigma 10-20 f4-5.6



learning my way around camera as well ,mainly finding what is not there compared to K3ii

excellent set Mike, love the Dragonfly

another excellently put together set, well spotted and well photographed. some have quite a minmal look yet have a lot to look at , excellent

IR converted arrived well packed and clean as a whistle as well, pleasure doing business with you doubled.
got a learning curve now , first lesson SDM/HSM lenses no AF, camera pre dates them. updated firmware so now accepts SanDisk Extreme 16g card

no, but it seems the manual says to use the Pentax "sticky sweet on a stick thing" and not wet clean. just wodered why not a wet clean or if anyone did have a problem after one. it was/is a different sensor to K5 series after all but dfferent enough to need a specialised cleaning method?

has anyone had a problm after a wet clean?
