I just bought a used Exakta VX with an eye level prism which appears to be working and even has relatively good shutter curtains - not easy to find! The lens it came with is the Schacht 35mm F3.5 Travegon, which I know from prior experience with the Praktina and Leica thread version is pretty darn good. The VX has two problems, possibly there is no good solution, but I thought it worth asking if there are any experts here. First the viewfinder is pretty dim, certainly dimmer than say the more modern Exakta VX1000, but not quite as bad as a Praktina from the same era. Secondly the prism has no focusing aid such as a split viewer or micro screen dots. As I recall prisms from the VX1000/500 do not fit older Exakta. My question: Are there any available prism upgrades or focusing screens available that might improve the brightness of focusing capabilities of this camera? I suppose the waist level prism is an option, but that's a little too retro for even me! What are the screen/prism compatibility rules among the Exakta 35mm SLR line? Despite these difficulties, I put up with this because Exakta does have one great trait besides its good looks (in my view): The lenses - so many damn fine ones of all manner from all over Germany (east and west), and even a few from Japan! This is the camera: eBay # 150695241314 http://www.ebay.com/itm/15069524131...NX:IT&_trksid=p3984.m1439.l2649#ht_790wt_1384 - it's on my desk now and I'll try to upload some photos of it and some results with it soon!
