It was by pure chance that I ended up with not one but TWO huge LOMO zooms a couple of years ago. One of them was the LOMO 35OPF18-1 20-120mm T/3.3 which is an absolute monster as you can see side by side with Canon’s EF 70-200mm f/2.8L, but the subject of today’s post is the much smaller 35OPF1-1.

This is NOT the lens I’m reviewing here!

This is a big one, coming in a big metal case full of Cyrillic writing. The 35OPF1-1 is a 50-150mm designed and made in the experimental optics factory CKBK (same plant responsible for the superspeed LOMOs and some of rares anamorphics ever). This 1984 model comes in OCT-19 mount – which is the Russian version of the PL mount, sturdier, of course – and I’m using an OCT-19 to EF adapter.

As a film lens, it was designed to cover a film frame, meaning S35 coverage. On full frame you get lots of subtle vignetting and some not so subtle vignetting at the wider focal lengths. On S35 it delivers optimal performance.

Getting the objective stuff out of the way: minimum focus is at 1.2m (4ft) and aperture ranges from f/2.2 to f/4 (T/3.3 to T/5.6 according to markings on the lens). Yep, it’s a pretty limited aperture and I don’t fully understand their reasons for it… Such narrow range ensures that the eight blades keep bokeh perfectly round through all values. All rings are butter smooth in this copy and the aperture ring is maybe even a bit too smooth, offering no resistance to turning.

This beast weighs 3.5kg (7.7 pounds) and measures 25cm (10 inches) from top to bottom. The filter thread is 105mm and the full focus throw to infinity is 300 degrees.

My copy is plagued with fungus, though. It came like that from the previous owner but, fortunately, the parasites are already dead, as they haven’t grown in the years I’ve had it. You can take a better look at the lens and the fungus in this album.

Oh nooo!

Now let’s move to the interesting stuff.

Every time I put this lens on the camera I think I should, instead of get rid of it, come up with ways of making it work with my style. This lens delivers all the artifacts I work hours to achieve in post. But here they’re at the perfect amount and much more organic than what I achieve in post.

Chromatic aberration is strong around the corners and pretty much on all high contrast edges at the longer end, the blue channel splits from the others. You can spot that around Ariana’s face in some of the close ups. It doesn’t bother me so much, as it seems subtler on the focused areas.

Speaking of focused areas, you can definitely tell when something is in focus, even at f/2.2 and the roll off to the out-of-focus areas is milky and pleasant, giving the image a dreamy quality that I seek.

Bokeh looks like soap bubbles – the famous and expensive trioplan look -, with sharper edges around the circles. In some shots you can notice a dark shape in the center of bokeh and that is being caused by the biggest fungus spot.

My favorite part about this lens is the blooming and flaring, definitely. You can spot it right away in all of the sunset shots and when strong light hits the glass. The warm tones and highlights bleed onto the darker foreground (mostly Ariana’s face or jacket) in a way that I am yet to learn how to fake in post.

All of these artifacts combined give the lens a look that is the complete opposite of modern glass, sharp, contrasty and clean. From now on I’m using this video as the supreme example of why I choose to shoot using vintage glass and pursue this road of exotic and unusual optics.

In terms of usability, this lens requires some sort of support system. From what I’ve seen in Olex’s video of its turnaround, there is a Russian support, but mine came without it. So far, I’ve been working out my arms, but if you want to use this in real life, you should really come up with a solution.

A good thing in terms of adapting this to modern cine cameras is that the original OCT-19 mount can be easily replaced with a PL mount.

Overall, this is powerful long zoom, going from a normal length (50mm) to super tele (150mm) able to keep a fast and constant aperture through its entire range. Size and weight are definitely a challenge if you’re shooting run and gun, but not so much if you’re used to cinema super zooms. All the optical craziness can be seen as a positive or negative factor, depending on how you like the look of your footage straight from camera.

If you like this lens and like what you read here, I’m letting go of it. Here’s the link to the listing!
