The Industar-61 2.8/52 that originally fits my FED-3 type b is an excellent sharp lens, and has never been disappointing me! And yesterday, while I went to one of my favourite shops here in Prague to get a leather case to carry my Pentacon Six (about 2 kgs, for this wonderful MF SLR camera), I saw a FED-5B lying in one of the shelves... my eyes brightened and while repeating in my mind "Industar 61 L/D, Industar 61 L/D" I asked the guy to handle it to me ... so after checking the whole camera that worked perfectly, and was OF COURSE fitted with a serviced Industar 61 L/D (the 2.8/55) in perfect shape, I asked for the price ... and well for 400 czech crowns ... I got it 😀
I love this city, hope I'll never ever leave Prague! 🙂
