Good evening,

I bought a 50mm lens with a Praktica and paid €15 for it. The camera is in excellent cosmetic condition, although it's quite dusty. The lens is dusty too, but I noticed that the filter threads are damaged; it took a hit in that area.


Where the word "coating" is written, is the defect present

Can I try using this camera?

I've seen a few videos where they give advice on how to use it. I can try it gently with this one. here.

Of course, you can try to use it. Please go ahead and go ahead. You'll find tools online to repair damaged filter threads, too, but they may cost more than you paid for your camera. Best of luck to you

what are other tools ?
 
The tool you need is called "lens vise".
Go ahead and use the camera. The dent should not affect anything apart from your ability to use filters on this lens.

Be careful when cleaning the camera and the lens. Take your time and be gentle. Research proper cleaning techniques. Here is a good reference for beginners (you can read it by registering to archive.org):

You can still use a push-on filter adapter rather than try to un-dent the lens.

Or just hold larger filters close in front of the lens - that worked for me yesterday even with a body cap fisheye that has no filter thread

Minor dents to the filter ring rarely have any effect on the lens itself, though impacts that caused severe dents might decentre elements.
