Makes sense - if I was starting from scratch today, I'd do the same. Due to very minor differences in flange focal distance between the two mounts, infinity focus isn't a given if the M42 adapter ...

M39 is just a thread dimension - L39 (Leica, sometimes also known as LTM or Leica Thread Mount), Z39 (Zenit) and other variations (Paxette for example) all have an M39 thread but have very ...

My similar age 44 also has a stiff front aperture/preset ring. You should be able to tighten the optical block sufficiently so operating that ring doesn't cause the whole lens to come apart. I ...

That's more like it! The Trioplan requires a change of mindset to get the best out of it. The soap bubbles are undoubtedly very distracting and don't suit 'normal' photography where you typically ...

Yes to the last sentence ;-) Think of extension tubes. Positioning the lens further away from the sensor decreases the minimum focus distance.

Seeing as it's unlikely you'll be using the lens for landscapes, infinity focus isn't really necessary but... if you can focus your current setup at infinity you should be able to take a ...

I think you're on the right track with this idea. It must be very difficult to get any kind of precision as it is with that coarse 'thread' on the barrel. The Trioplan is not really a sharp lens ...

That's highly unlikely so I'd say it was mostly BS. I'm no scientist but my preferred version of the truth (!) is that fungal spores are literally everywhere but require particular conditions to ...

Depends on the lens. Some seem to clean up relatively easily with no lasting damage and that largely depends on the coatings used when the lens was manufactured. Getting to the element(s) that ...

Absolutely. I thought it was a bit extravagant for just the one lens :-D Isn't that the same as the Contax/Kiev mount?

If that serial number followed the same sequence as their camera lenses, it would've been made in the 1920s. I doubt that's right. It looks more like a 1960s lens. Hard to tell. Good luck with your ...

That must be a special lens to be worthy of investing in the most expensive helicoid ;-) Hope you can share a few shots sometime.

I think Meyer serial numbers are sequential and don't have date codes. Have a look at http://camera-wiki.org/wiki/Meyer_serial_numbers Meyer Optik ceased to exist some time in 1971, merging with ...

I've used a couple of LM close focus adapters on Sony. In my experience, the cheaper one worked OK for a month or two but then developed play in the helicoid which gradually got worse and it ...

I think we got ours during morning break. Not bad when it was cold, but in the summer months the milk got a bit too warm for my liking ;-)

Thanks Alan. I agree with you on the framing. The radiator in the background isn't the most attractive backdrop! It keeps her warm and comfortable through the winter months though, despite it's ...

The 100-300 f5.6 L must be the only L lens you can buy for less than £150 for a good one. It has good optics which include a Fluorite element. It's decently sharp and with minimal colour fringing. ...

My dog with a 1949 Meyer Primoplan. She's almost 14 and not very active these days preferring to spend most of her time on her bed. These were shot in B&W using off-camera Godox TT685S flash with ...

These lenses are really easy to take apart. Mine has many missing screws so it's self-disassembling ! The focus ring is attached by 3 set screws. If you loosen those, you can remove the focus ring ...

Found this one with worldwide shipping: Fotasy/Rainbow Imaging adapter
