When I first fired up my Minolta Mini, my first thought was that this little sucker could burn my house down. If you want to really appreciate projected slides, I suggest getting a nice, late model, autofocus Kodak Ektagraphic and a quality screen. They are tiny and, well, made by Minolta. I use a Minolta Mini 35 mounted on a Minolta Blower. I don't have any connection with either of these auctions - just thought I'd share a cool tool for the slide photographers in the crowd. The 8" screen is plenty big enough to check focus and behold the bountiful artistry present in my (mainly crappy) pictures. I get my slides back from processing in a box - it's real easy to grab the stack of slides, drop them into the feeder, transport them through the viewer, remove the stack of slides and drop them back into the box - almost a dust-free operation. The construction is kinda cheap, but the design is real decent. The Diastar is very simple, uses a small halogen bulb that is widely available (not photography specific), folds up a little and is easy to clean internally. Most of them come with an audio cassette player that has an auto-advance feature so they can run unattended. Here's one on eBay:Ī zillion of these were made by several different companies, mainly used as A/V displays in booths or showrooms.
They use a projector-type lamp, generate a lot of heat (cooled with a noisy blower) and are next to impossible to clean internally, so they deposit dust very efficiently and evenly on all the slides. These take a carousel and auto-feed slides through a complex mechanism. The Caramate-type viewers work all right. Prior to the Diastar, I have used an old Caramate, a light box, or one of those battery-operated Panavue viewers with the teeny, ill-lit screen. I recently bought an Osram Diastar 200 slide wiewer for previewing and sorting before I load the keepers into a carousel for storage and display. The projector's base is marked "100W max", but I've read that the power rating of a fitting really refers to the highest temperature it can cope with.When I shoot film, I shoot slides for projection almost exclusively. I've scoured the internet for bulbs of the same type, but the only 100 Watt bulb I can find is £30! However, for £5, I can get a 200W bulb with otherwise identical specifications. It has a small single-pin bayonet fitting which (from online searches) appears to be referred to as BA15S or A1/83. I've recently purchased a Minolta Mini 35 slide projector to view my Dad's old slides and it's worked absolutely great until today - the bulb has blown! The original bulb was only marked with the manufacturer's name (Kondo) and the voltage/power (240V/100W).
