Got my Prakticar 28/2.8!

[DiegoV]

I mean, I just paid for it... It's supposed to arrive in the next few days.

With the rising price of the PB lenses, I think I got a great deal (assuming the lens is in good condition, as stated by the seller)

I'll be posting some pictures of the lens as soon as it arrives.

Cool, which Praktica are you going to use it on?

[DiegoV]

I'm going to use it on a Praktica BMS and on a Canon 350D with the PB to EOS adapter

[ManualFocus-G]

Cool, I use my PB lenses on a BX20 which gives nice results Haven't tried the 28/2.8 but hopefully it will give you nice results, although I've heard it's difficult for these lenses to reach infinity on Canon EOS bodies.

[DiegoV]

I bought it essentially because I needed something wider that the 50/2.4 for the Praktica BMS. As for the 350D, the lens becomes something like a 45mm because of the 1,6x crop and I plan to use it on some creative portraits (yes, who said portraits have to be shot at 85~135mm? ) so, the issue with infinity focus (which I have experienced with both the 50/2.4 and the 70-210/4-5.6 on the 350D) won't be a problem

It would be a problem if I couldn't reach infinity on the Praktica body...but that doesn't happen, of course

Hi,

I have a Prakticar PM 2.8/28mm MC Pentacon with M42 screw-mount. I bought it off eBay and it had some fungus, which led to a discount. When I dissembled it and cleaned the fungus and dust, I put it all back together, however, I guess I might mess one or two little lenses inside (put in a wrong direction or order), cause I have a blurry edges on photos. I use Praktica PLC3. I wonder if you have a scheme or anybody here knows where I could get one, so that I could place the lenses in the right order =) Thanks in advance

Congratulations. Pr28/2.8 is one of nice 28mm lenses, it is sharp and
hardly any distortion.

I found the mistake, so it should work properly now...fingers crossed

[DiegoV]

I never tried opening and cleaning a lens before... is it a very hard thing to do?

[Guliver]

I wouldn't say its hard to, but you have to be very careful and always put details in the right order or even draw a rough sketch what and where was placed in the lens (still learning on my own mistakes hehe). I don't usually open them just for fun, it is usually a necessity (once there was a screw stuck on my zoom lens, so I had to take it apart to find out what actually happened). This time I bought a lens with a little of fungus, which was on the inner side of the glass, so I had to open it and sterile everything inside, so that I could just put that lens on my camera without infecting it. However, sometimes it can also be a lot of fun. For instance when I started putting all pieces together in my Practicar 2.8/28, I accidently placed a metal ring before one of the glasses, although it should come after, so as a result I've got even wider angle of view (I think it could be equal to 96 degrees or 20mm) and the sharpness was still at the top. But obviously the focusing meter marked on the lens was no more accurate.

[DiegoV]

That sounds fun indeed .
And if you do everything right you can get a nice lens for a fraction of the price (if it has dirt or fungus inside...then you just open it and clean it )

[Guliver]

Exactly! There were many instances, when my skills and/or experience saved me a lot of money

[DiegoV]

I guess I'll keep reading tips on how to do it and maybe one day I'll be able to open and clean a lens

Thanks, Guliver
