Asked by: '$ - Bug Hunter
I bought this lens for my wife. She absolutely loves it. It is very light and very sharp. However you should know that, like all the other lensbaby lenses, it has only manual focusing, no AF.

Does this lens have an Ai coupling ridge. In addition, is the aperture scale visible in the viewfinder of a Manual Focus film camera like the Nikon FM2n? It looks like it does but the illustration is not clear.
Asked by: Robert
No, aperture is not visible in view finder.Ai coupling? It fits my nikon fine with nikon mount. There is no connection to body threw sensors.. it locks on and you do everything by hand. You can see shutter speed and iso on back screen or inside view finder

Will this lens capture full circle images while using Speedbooster Ultra 0.71x on a Blackmagic Pocket 4k?
Asked by: Rajesh
No, the sensor size on the Black Magic Pocket 4k even by itself (without the Speedbooster) will not yield a circular image. You will see cropping on the top and bottom on any sensor size besides a full frame sensor.

Will this lens produce a full circular image on the MFT sensor?
Asked by: Anonymous
No, this lens will not produce a full circle image. It will produce a circle cropped at the top and bottom. You need about a 4.5mm fisheye lens on a 4/3 sensor to produce a full circle fisheye image.

Does this give a full circle image on Fuji, or is it cropped top and bottom due to the APS-C sensor?
Asked by: Matthew M.
Here is our crop comparison chart for the Circular Fisheye Lens: https://<a href= target= _blank ></a> On a crop sensor camera you will not see black around the entire circle.

Do filters fit well on this lens?
Asked by: Anonymous
The front lens element protrudes beyond the end of the barrel. There are no threads for attaching a filter. The lens has a 185 degree field of view so any improvised way of attaching a flat filter will impact the field of view.
