Not quite sure what you are saying. I was referring to the lenses themselves. It used to be that you either had to buy a lens specifically for UV work (expensive) or remove coatings from lenses to get them to pass the UV wavelengths to film/sensor.At 380nm, the glass would pass all the UV radiation.
Many coatings on modern lenses block/filter out UV/IR. It may not affect the limited UV (Fuji didn't go very deep into the UV spectrum of the wavelengths that they'll allow to pass to the sensor) that this camera will allow to pass through to the sensor but I would assume some testing will need to be done with existing Fuji lenses to see if they are UV capable. Many older lenses are, most are constructed with fewer than 5 lens elements, and fluorite elements are common in UV capable lenses.Doug, the highest frequency wavelength the camera is sensitive to is 380nm. Regular optics will pass that wavelength with no loss. Lens coatings do not limit bandpass--lens coatings increase transmission. The cut filter over the sensor is responsible for limiting bandwidth. How corrected optics are for UV or NIR is a different matter...
The information is on the internet and performed by many scientists. Vivek Iyer is one of many that has tested many lenses for their use specifically for UV Photography purposes. You can Google search the information but there are several great sources.Why would Fuji release a UV/IR camera when its lenses would not work with the body? I would be interested in seeing source where you are finding lens manufacturers are putting filtration on their lenses. Since the sensor is filtered, it would seem redundant to filter the optics.
I am not sure the point you are trying to make about Fluorite lenses. It usually means it is better corrected than a non-fluorite lens, but that does not limit the useful spectra. Fluorite lenses are used on microscopes for fluorescence and regular broadband.
I am not sure why folks are saying the UV sensitivity is limited? I do scientific imaging, mostly with compound microscopes, the UV wavelengths the camera is sensitive to is where natural auto-fluorescence can be found. If you want to go deeper into the UV, you are going to have to get very specialized equipment, same for IR beyond 1000nm. This is kind of like looking an an aircraft and then complaining it can't get into orbit. Well, you can do an awful lot with an aircraft, just like a sensor that is sensitive to 380nm can do more than a regular sensor sensitivity.
I think before folks worry about the camera, it might be better to figure out how you are going to get this UV radiation and how you are going to have to filter. The camera might be the least of your worry.
The camera might be the least of the worries when the lenses aren't upto scratch. You are assuming that Fuji have made lenses that transmit UV even to 380nm. Are there any transmission charts available for that? Even if one assumes good transmission through the glass elements used in Fuji X lenses, none of the modern lens cements (unless it is special) used will permit UV(they fluoresce and project fuzzy pictures).Why would Fuji release a UV/IR camera when its lenses would not work with the body?
