Megapixel & Resolution Reality


Today, I ran into a fellow photographer who ALSO paid a ton of money for a digital camera a number of years ago. He has the SONY DSC-F707 (5 megapixel camera) and was looking for advice on whether to keep it or get one of the 'new' cameras. The Carl Zeiss lens on his camera made me tell him no! No, keep it - it's the sharpest optical glass on the planet - and any 8,10 or 12 megapixel camera produced today wouldn't compete with the sharpness and resolution of that lens. The glass itself on the camera is about 1 inch in diameter - and it's in the lens that the image is first created.

He laughed at my answer - and told me that he had made a 15 x 30 (foot) image for the side of a truck with that camera - with that lens!

Him trading in or giving up on this camera for the luxury of saying "I have one of the new ones" isn't even close to being worth it. He'll get many more years of professional use out of this camera. The design is unique - it's the best optical glass made, and the lens ISN'T only about 4mm in diameter, like on the 'new' technology cameras.

He paid $1400 for it when it came out, but the quality of the images has been worth it!

Distortion in digital cameras

I have a number of cameras - from standard 35mm SLRs to 2¼ format to a couple of view cameras - and a few digitals.

Having used the Nikons and Mamiyas as well as my 4x5 Horseman for a lot of client work, I know how they handle, and what quality of image the lenses deliver.

I'm noticing a certain amount of distortion in a number of the consumer digital cams. I recently picked up a Fuji S700 as a quickshooter and have noticed that shooting a square or rectangle head on (in both wide angle and 'telephoto' mode) results in a pincushion.

If there are any pros out there - or anyone shooting for publication, would you let me know what camera(s) you're using and what type of optical distortion you might have encountered?

These quick shoot digital cameras are great, but my question is - are they great enough for a picky art director who might wonder why you didn't shoot his assignment with a Nikon F using a 105mm / 2.5 instead of the digital...
