Just learn to use your current software to its greatest potential, then you can go lusting after fancier stuff!

They both have winders, have been heavily used, and they still work fine!
I got them on the theory that "if it isn't there, it won't break". So far so good!!
But now the business has gone digital, so I'm really glad all my old lenses work on the *st D just like they did on the MX - take a reading, compose, shoot!

You may need to assign a drive letter to it.

I use a LaCie Electron Blue monitor, it's specifically a graphics monitor.

Besides, you can use a linear polarizer in front of a circular polarizer to make a continuolsy-variable ND filter. The problem is you now have four extra surfaces to keep clean!

I managed to find a used Polaroid Sprint Scan 120, so I can scan 35mm and 120 film. But if you only have a few slides to digitize, the copier method may be just the ticket!

Not long ago 4 or 5 megapixel cameras were good enough for double-page spreads in magazines, so why are the six megapixel cameras suddenly not up to snuff?
Kodak has a sensor out that's pretty much full-frame 645, and it has to be that big to squeeze 31 megapixels in withoug turning into a noise factory!
You could always shoot RAW and render the file at 12 or 14 megapixels. But what do you need all those megapixels for? Generally you're eventually outputting to a four color offset press that can't even provide the detail that a four megapixel camera is capable of.
By the time you get to 5 or 6 megapixels, you're at the 35mm film level of quality. What counts is the quality of those megapixels, and the sensor.
Those 8 megapixel digicams with the tiny sensors were a disaster! There's an upper limit to what current tehnology is capable, and the 6 megapixel sensor is pushing the ceiling.
They could squeeze 8 or 10 megapixels into a full-frame sensor (preferrably not with a 2:3 aspect raio but something more like 3:4 or 4:5) but even there you run into a limit. Hence the medium format backs.
