I have a Praktica LTL, which I haven't used in MANY years - perhaps thirty! -, since I went to Pentax and the mighty LX. I unearthed it recently and the shutter sounded correct, at least to the ear. The slow speeds sounded good. My 50mm f1.8 "kit" lens needs a CLA, since the auto diaphragm is sticky. That lens, BTW, is quite sharp, easily capable of 11 x 14 enlargements, and focusing down to about18 inches is really nice! What other SLRs can do this, and why not?
I haven't tried the meter, but I imagine its fine. This is a camera heavily used, bounced off the sidewalk at least once! It has, IMHO, the best implementation of stop-down metering in a 42mm SLR that there is, excluding the Spotmatic F which is of course full aperture metering.
While the LTL is not the best in fit and finish, and the viewfinder could be brighter, for a rugged workhorse camera, capable of taking abuse and continuing to work, and work well, it is a winner.
