Sounds like you have answered your own question. Time to dump the Sigma and buy a Pentax instead. (I have already said Sigma was shit many times and nobody believed) :)
regards, Alan Chan > As I mentioned on the list a month or two ago, I've had a lot of >trouble getting sharply focussed results from the Sigma 15-30mm EX lens I >bought about a year ago. In fact, I don't know of a single acceptably >focussed shot I've had from that lens. I had been using it with a Z-1 and >an MZ-5, doing the focus manually using these cameras' matte screens. > > Now before you tell me that my technique must be at fault, let me >mention that I do all of my photography with manual focus, since most of my >lenses are manual, so I've shot an awful lot of film this way, always with >good results. I also tried the Sigma on the Z-1 in auto-focus mode, >shooting some easy-to-focus subjects, and with higher-than-necessary >shutter speeds, and again the result was unacceptable. Of course, the >processing lab might have been at fault, but I use them an awful lot and >rarely have problems with them. > > So finally I got really desperate, and shot a roll of 36 exposures >using this lens mounted on my entirely manual MZ-M camera. I just got the >film back, and darned if every photo isn't sharp as a tack! As you >probably picked up from the title of this email, I did all the focussing >using the split prism. I was concerned I might have to junk this lens, so >it's a relief to know that everything's OK. _________________________________________________________________ Join the world�s largest e-mail service with MSN Hotmail. http://www.hotmail.com - This message is from the Pentax-Discuss Mail List.
