All Tevidon prime what I did try was superb, I never seen this lens. I did try Angenieux in similar focal length range it was excellent, but vignetting on m4/3 in whole range.If you can live together with very strong vignetting at wide end may you will love it.

I have a Schneider in same length at f2. but it does vignette a lot regardless of the focal length.
What's the camera you will be using it with?

I have it since a few days. Looks decent for a zoom so far, very fast (F2 over the full range!),.... like all Tevidons it's build is pretty heavy though.
It vignetts on every focal length on APS-C, especially in the mid range. At the long and maybe at the short end it might cover 2x crop.
I've only used it for low light handheld so far, so I have no meaningful samples so far.


Vignetting@90mm wide open
It's only 1/60s on an full spectrum mod. 1.5x crop camera - so don't judge sharpness and vignetting


don't know focal length here

I have seen some of these vario lens go for 50-60EUR

So the sensor is smaller than m4/3 and may work without vignetting then.

I hope so


It shoots raw video or will do after FW update

WE dont have the specs yet on the stills side

But it blows my plans for a cheap Nikon V1 out of the water

Not ideally attached to my camera...

The lens, new out of box, just mount modified to allow c-mount adapters to fit.









(all the motors attached to have been removed, so it's just the lens)

"little" is a very relative term it seems...
