Testing of lenses

hello all, I hope you are well. As some of you know my gx20 has been sent away for repair or replacement. however id like to get the lenses checked, sigma quoted me a cost of £89 per lens just to check if they worked or not, it seems a little steep to me thats all

I wonder what you want testing? You know if they focus or not and you also know whether or not they are sharp. I'm not sure what else you need to know, although I guess that you might have concerns stemming from your bad camera luck on your trip.

I would wait for the camera to be returned to see if there is a problem. If there is with some lenses then fair enough, but if there is with all of them then it's probably not a lens problem.

hello john. Well i only took the 17-70 to thailand, and lots of the images are just poor, no definition of edges , colour totally wrong, but then some of the shots are fantastic. I cant even put it down to technique as lots of the images with a obvious focus point look terrible. I guess you are right wait for the cameras outcome and then go from there.
