Equipment - tools of the trade: August 2005 Archives

Someone's written a small depth of field calculator for Mac OS X dashboard widgets. I'm not sure how useful it is to pop open your PowerBook before you want to take a photo -- that's what the DOF lines on your lens focusing ring are for -- and the PalmOS ones are much handier if you need more detailed info, but I guess some people might be interested: DOFC - Depth of Field Calculator - Dashboard - Calculate & Convert: ""

About DOFC - Depth of Field Calculator
DOFC is a handy calculator for the depth of field, near focus, far focus and hyperfocal distance, no matter what camera you’ve got. It’s the perfect companion for the Apple PowerBook or iBook you probably carry to store and touch-up your digital images. DOFC will hopefully make a welcome addition to your shooting set-up, whether you shoot for soft Bokeh in portraits or ultimate sharpness in panoramic images.
DPReview.com breaks the news that the Canon EOS 5D and 1D Mark IIN have been officially announced.

The 5D specs were posted on this site previously and appear to be accurate, except for the price which is estimated at US$3299. That's ground breaking for a full-frame camera.

I'm now living by the ocean and the humidity is quite high. I'm going to give this a go and report on how it works. See my previous blog entry on keeping cameras and lenses fungus free.

Some members of the Leica Reflex list found that their manual focus Leica-R lenses were having slight exposure problems when mounted (with an adapter) on their Canon EOS 20D cameras. This was a problem that hadn't shown up in previous EOS digital or film cameras.
