Hi Tom: Things to check...
1) It's tempting to stop down too far to get depth of field for product shots. What f-stops are you using? 2) Lens hood may help cut down on scattered light 3) I'd depend on auto focus over manual focus most days - autofocus works pretty well on sharply defined product edges on clean backgrounds. 4) Not sure on that lens if you have IS turned on whether that can cause problems on a tripod in a studio setting (where the camera is very still). 5) I'd shoot faster than 1/100th if you have the light (and you often do in a studio). I've had the same problems doing product shoots and the thing that caused me the _most_ trouble was stopping down too far going for depth of field. Especially shooting on white backgrounds going for a hi-key look I think the lens hood is a good idea - lots of light scattering around. Next product shoot I do I'm going go all HDR, too. Say... what's the best product shot lens out there for depth of field? Which lens performs the best stopped all the way down? -Bob -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Williams Sent: Wednesday, November 29, 2006 11:15 AM To: [email protected] Subject: EOS Blurry pics. Hello all, I am currently working on a presentation for work. I've taken some photos of the piece of equipment that is being introduced with the following: Eos 5D 28-135mm f/3.5-5.6 IS Tripod Cable release Manual Focus Mono light w/ umbrella Shutter speed was 1/100th When I brought the pics up on my computer screen I immediately noticed that they all looked slightly, but noticeable, out of focus. Not on the camera screen though. I spent some time today with the camera and lens combo checking my manual focus against the auto focus on the same point and it was on every time. I know that my diopter is set right. I've heard/seen posts that the 28-135 seems "softer" to some with a digital as apposed to film cameras. This didn't look soft, I would say out of focus. I haven't been doing digital that long so maybe I'm missing or not under standing something. I've never had to re-shoot pictures before now. Later today or tomorrow I'll have to retake them. Any help/suggestions would be greatly appreciated. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
