Interesting, but I do not get what that SLR-ikon (to name it this way) is hinting at at all at that billboard.
(Slow on the uptake again...)
...Not sure why they thought a Praktica is cool though...
Well, maybe they think it's cool because it doesn't look like a cell phone.
How many actually have a clue this is a photo of a Praktica, name plate is wiped off.Maybe they are smart?

That we have 26 Photrio pages discussing the Praktica shows that the camera indeed has respect.

Ummm....Not quite. The Praktica LTL, and to the best of my knowledge other cameras using a needle to be aligned with a central target, like the Pentax Spotmatic F, use a bridge circuit, which is relatively immune to REASONABLE voltage differences. Thus the original mercury cell of the LTL and many others, with a voltage of 1.37 volts can be replaced by a silver oxide cell at 1.5 volts with no effect on accuracy. The bridge circuit indicates by centering the needle equal voltages in each half of the circuit, one half set via the ASA or ISO setting,and the meter cell, the other half by either or both the aperture or shutter setting. I think that to check whether a camera uses a bridge circuit just remove the cell. If the needle then rests on the "target" it is then a bridge circuit. When the needle is centered there is no voltage difference between each half of the bridge. So if there is no cell present there cannot be any voltage. I suspect that there are limits to the voltage the circuitry can utilize.I've read on flickr and a couple of other sites that due to the camera having a Whetston Bridge circuit, one can use a standard AA battery instead of the original cell. I'm going to take a look at a VLC3 tommorrow and l'd like to test the meter to see if it works at all.
It will react with an AA cell but it won't work properly.Yes, l've found a suitable replacement cell for my LTL3 (a PX625) and it works just fine. This ''trick'' with the AA battery seemed too good to be true to me, but then again l did read about that on a couple of different forums.
Be that as it may, the only important thing to me would be that the meter reacts at all, which would mean that it is alive, and would possibly be accurate once l place an adequate battery inside.
The Praktica LLC, PLC3 etc use the discontinued V21 PX 4.5 volt batteries, although you can buy replacements from battery companies which are quite expensive at £9 or so a go.
What I did was make a cell holder from the barrel of an old felt tip, a spring and three LR44 cells taped together, cost less than £1.and it works.
(Size 21 is so rare over here that in my battery collection I so far just got 1 sample.)
I have an opportunity to get either of two Pentacon 200/4 lenses, one of which is the preset version with 15 aperture blades, and the other one is the newer electric version with 6 blades. Which one should l buy? The electric one has an advantage in a sense that l can meter with it wide open, unlike the preset. Does the preset version have any advantages image quality-wise over the electric, since the consensus on various forums is that the preset version is the way to go? The price difference is about $10, electric being the cheaper one ($30).
super easy screw mount
To my understanding the optics are the same (Meyer Orestegor).
I find this statement disturbing.
What we found "disturbing" was that the Nikon/Canon/Olympus/Pentax versions of the same lens was between 20% to 50% MORE than the screw mount version! I shot hundreds of B&W rolls for publication and my 50mm Pentacon was beautifully tack sharp with nice contrast.
I never had any problems with M42 screw mount lenses but I do prefer bayonet/breach mounts.
What are the supposed problems with screw mounts? Does the thread get damaged over time?
