Unless you can actually return it and get something else, it's all a tad irrelevant. Get some 35mm film ASAP, shoot it and enjoy it Ian. Everything else doesn't really matter![]()
Oh, that changes things then. Return them.
The LLC uses a PX21 battery which is an expensive, uncommon battery - you won't get much change from a £10 note for one from the small battery company here. The BCA uses a slightly more common 6V battery, but again these are not as common as button cells (it can use button cells, but four of them slapped together). The BCA doesn't have a way of allowing you to choose shutter speed properly, the dial only has four limited options rather than a full range of manual speeds.
Also, the LLC features an alarming amount of electronics for a 70s camera - and in my head, 40 year old electronics + East Germany don't create a reliable shooter. Additionally, it seems that a lot of the electronics were moved to the lens, so you have electronics in the body and the lens to rely on, and that probably limits how many M42 lenses that you can have access to with full usability.
etc. etc.
Apologies, that's probably the post you wanted to read rather than my original reply. It's just that with used cameras, most of the time the only places you'll be able to return to are dealers, and all the dealers I'm aware of don't stock any Praktica's - usually Praktica's are sold in boot sales and charity shops (i.e. places where you can't return).
It's M42 right (the lens mount by being screwed in?). There's a thread on pentaxforums about it - well, where they try to work out more information about it: http://www.pentaxforums.com/forums/...on/16435-anyone-familiar-praktica-lenses.html
It's only useful to keep if you want to shoot it on your digital body, but the adaptors for M42-Nikon are a bit rubbish, and only if the camera you want to replace the Praktica's with is also M42 mount.
There's lots of good stuff out there for £50 and less, just have to find it!
