I've got a tiny Elgeet lens with an indication of maximum aperture on the barrel which is f2.3. No other indication of the focal lens or further aperture values is given. The resulting image gives a focal of around 35mm.

The lens has a small aperture lever, I presume intended to couple it with a distant adjustment lever. The mount is absent, it is a round plate with three holes. The lens itself is screwed into a small cage that allows focusing. Everything shows it was in technical use, kind of airplane or surveillance camera.

The lens barrel is as small as 22.5mm in diameter. The flange distance is also small, I had to put it on Nex-M39 adapter with a custom ring and some scotch, and make it recess into the adapter to reach infinity. I was wondering the quality (sharpness), but first of all the image circle.

It does not cover FF, but works with APS-C giving quite a special, not swirly, but rather interesting OOF out of center.

#1 Put on Sony A7, wide open


#2 On Sony A7 switched to APS-C mode, with the diaphragm slightly closed


#3 Close range, the diaphragm the same way slightly closed


#4 It's interesting how fast the image portions go OOF giving this special fuzziness, pleasant at my taste


#5 Freelensing w/o macro taken on Nex (a detail of a wooden chair)



The lens is not sharp w/o, nor particularly sharp closed down a bit. It's more a special effect instrument, with its character to render out of center portions of the image. I ask myself it it might really be used in air photography, or it's another kind of optics.

If someone is interested, I will take a shot of the lens itself and will post it here.

I think it's worth a try putting a runner/cyclist into the center of the frame.
That's the first thing that crossed my mind seeing this "speed" effect.

Thank you, Klaus! That must be the speed effect that the lens transferred to my typing...

Thank you, Bernhard!

I haven't yet captured a jogger, as aidaho suggested. I took a car instead, but not close enough wishing not to risk my health. Here it is and a couple more outdoor shots taken on Nex.

Number 3 makes me think about 1980s movies, a scene where protagonist suddenly remembers something important Very Happy

Here I add some night shots which is always a test speaking much about the lens. In the dark this small Elgeet gives up its "speed" effect and reveals another side of its character. Sometimes well surprising.

#1 The light spots getting nice oblong ellipses are already seen in the daytime, but in the dark they get better visible


#2 Much of the light in the dark gives a strong retro effect, other than speed


#3 I am pretty puzzled with the OOF shape when the diaphragm is closed a bit. While the aperture shape is round, the light spots get cross shaped!


#4 A 100% crop from the previous


#5 At shorter distance and under upper artificial light the lens gives an impression to be sharper than in the direct sunlight. Another surprise.
