ok... so please do no treat this thread as canon vs nikon discussion! So you know that I'm buying dSLR. but of course I dunno what to choose - nikon d50 or canon 350d. and you probably know that I'm short of cash so here's the question. Some people told me that with nikon I won't be able to use my old lenses from zenit because it doesn't meter light through such lenses. i know that in canon it is posiible. I also heard that lenses to canon are cheaper than those for nikon... my question: I found on ebay something like this: http://cgi.ebay.com/LENs-Mount-Adap...587494290QQcategoryZ30066QQrdZ1QQcmdZViewItem does it mean that all the functions like light metering will work? what do you think about such stuff?
