Disassembling, cleaning mir-1b 37mm f2.8 89045432

Описание: Hi, my name is Dwayne, and I'm all about vintage lenses – the kind that you sekali cuba, hari hari mahu.

Which is exactly what happened to Mr. Andrew after he tried the Helios-44M.

So, Mr. Andrew ordered a MIR-1B, this fantastic wide angle Soviet lens with that same mesmerizing swirly bokeh you get from the Helios 44 series.

First, I carefully relubricated the focusing helicoid and aperture ring with Helimax XP NLGI #1 Lithium grease. Smooth as butter now.

Then, I carefully cleaned those optics with IPA 99% to ensure there's not a smudge or mark left.

Next, a little tweak for modern convenience. I modified the aperture ring to be a 'single action' champ, making it user-friendly for today's shooters.

Swapping out those frail aluminum grub screws with gleaming stainless steel ones has transformed it into a lens as robust as a tank.

I've reduced the minimum focusing distance from 0.7m to a convenient 0.5m. You'll be grateful for this in the future.

Of course, I gave it a good test run. Focusing helicoid and aperture ring feel just right.

There you have it. Mr. Andrew's MIR-1B is now a vintage lens wonder, ready to capture some cinematic magic.
