Just got a Fujinon-TV 12.5mm 1.4 C Mount

Mint condition with a box.

Fits my C - NEX adaptor perfectly without needing mod (Doesn't touch on the sides before butting up flush to the mount)

First impresions are that it products a 20mm image circle so it vignette is not to bad. (would be good on a 4/3's with its 21mm diag)

Seems realy sharp in the centre (f2) but will have to wait till tomorrow to get a few better pics to post.

Doesn't seem to be anything on this lens in the Forum.

Anyone got one....

Nice lens - Please tell me what you think?

Shot with NEX-5 (APS-C Sensor)

This would be a good wide Lens for all the Nikon1 and m4/3......with the Large NEX sensor this works out to be about a 22.5mm(35mmequiv) which is not so wide....but hey it is a F1.4


Will post the original first then the Crops.

(F8 )

Crop1

Crop2


(F1.4)

Crop1



Crop1



Crop1


(F5.6 I think)

Crop1

Hi Iaza

Ignore my maths and 35mm equiv calc.....I've messed up....

I'm sure one of the more knowledgable guys will correct me shortly.

I guess that this lens was designed for a 1"tube(16mm diag sensor size)

Therefore the inner usable 16mm of this 19.5mm image circle should be a 12.5mm FOV ??????

Personally it doesn't look that wide.

If you use just the inner 16mm (same as Nikon 1 sensor size) then the FOV is equivalent to 34mm lens on a full frame camera:

12.5 x (diagonal of full frame) / 16 = 34

I modify this lens for fuller sensor coverage. You can read an independent review of my 12.5mod here, with sample photos:

I can do this modification on your Fujinon-TV 12.5/f1.4. I offer other modifications and lens servicing as well.
