Vivitar (Komine) 400mm f5.6


I am a nature photo/videographer on a budget.
Yes, I am aware that, in most cases, it is better to have very good glass and a decent camera than the other way around.

Six months ago I invested in a Blackmagic Pocket Cinema Camera 4k. I have some good glass and a handful of vintage lenses. By the way, the Blackmagic is a formidable camera, and its image quality extremely good.

I own a Panasonic 100-300mm F/4.0-5.6 and I’m happy with it. On my BMPCC 4k, this means having a 600mm and, using the HD Windowed crop even a little more.

I want more though. Like a 400mm or a 500mm. Or the Tamron or Sigma 150-600mm.
My daughter’s studies at university are far more important. Besides, she lives with me.
So forking out about 1000$ for a lens, well, not any time soon. Maybe next year.

A few weeks ago, while browsing a well-known second-hand site I came across a vintage Vivitar f5,6 400mm with an Olympus OM-mount. I still use an Olympus OM-1n occasionally, so that’s a bonus.

I checked a few online reviews, a few YouTube clips, and examples on Flicker and wasn’t very convinced but, well, who knows.
I offered 80 bucks for the lens and my bid was accepted and a few days later the lens arrived.

This is really a heavy lens and made for full-frame cameras. It weighs 1277 grams (2.8 pounds). The filter thread is 77mm. The iris is an 8 blade one and it had internal focussing.
The closest focus is about 6 meters.
It has a retractable lens hood and the lens measures 28cm in length.

Fortunately, it has a built-in tripod collar because there is no way you’ll be shooting handheld.
Obviously manual focus, basic lens coating, if coated at all, and it goes all the way to f32.

On my BMPCC 4k, this is a whopping 800mm lens. Best part? I have a 2x Tamron teleconverter for OM mount lying around giving me 1600mm shooting pleasure.
Well, no.
Not really except if you have an extremely sturdy tripod and a smooth head.

I haven’t used it much yet but I tested it out filming ducks on a pond.
At used it without and with the teleconverter. Focus peaking and a decent monitor are a plus. I did not shoot wide open but around f8 to f11 at 400 or 800 ISO.

The results?
Well pretty good actually. Soft, even at f8 or f11 but using some overall sharpening in DaVinci Resolve helped.
I tried adding some USM in Fusion and together with the sharpening in the color tab of Resolve I did get reasonably sharp images.
It is good enough to be viewed on mobile devices.
