Hello. I recently sold my FS converted Sony A7s and looking to convert to full spectrum new full frame or crop sensor mirrorless camera with ~20Mp resolution. My main requirement mirrorless camera is being enhanced sensitivity in UV/VIS/IR spectrum (or even reaching SWIR) after full spectrum conversion but features in newer models like IBIS, phase focusing, high native ISO. 4K recording, better viewfinder, high refresh rate, pixel shift (or other way to boost static object resolution) is also desirable. I would consider A7s III as the best choice if it had pixel shift technology to boost camera resolution but despite being new camera with IBIS it hasn’t it. Would it be possible to add pixel shift via firmware or it’s hardware problem? I was disappointed that Sony decided to add this feature to already ridiculous resolution photo camera’s but not to A7s which could have made use of this feature to deal with it’s main disadvantage low resolution and moire effect. 60Mp is already too much and sensitivity is suffering. Who needs 240Mp photo??? Camera makers should listen more to professional photographers and scientists, and not to stupid amateur opinion who think that only increasing number of megapixels matters. There are tossed ideas that Sony A7SIII has actually 48Mp pixels due to quad Bayer sensor design, that‘s at least in theory but is this possible in practice? Did A7s III and II reduce native ISO sensitivity down to 104200? A7s I had native ISO sensitivity of 409600 despite not being backlit CMOS? Expanded ISO is just deceptive marketing? I will also need a high quality lens that is fast and sharp both in IR and visible so I need to factor this into camera selection. Canon and Nikon seems to have bigger selection of lens than Sony in terms low infrared hotspots. Is there new sensor technology being used in mirrorless camera’s or even alternative to outdated silicon CMOS sensors that have limited spectral sensitivity. Camera sensors did not change really much. Major shift was use of backlit CMOS sensors which are better f-stop in noise reduction and I read they are also more sensitive especially to UV but later camera sensor are also using coatings which may block UV/IR. Sure there are small improvements like dual gain pixels, stacked or global shutter sensors but these novelties have no effect on spectral sensitivity? I read about Canon experimental SPAD camera sensor technology that can use multiplied electron avalanche to amplify signal sort of like analog night vision devices but are still in their infancy. Quantum dot three layer sensor are also in development. Even more amazing is graphene-enhanced CMOS. High sensitivity is really needed to reduce pixel and camera/lens size. Are there any cameras that use different color filter mosaics with better IR/UV transmission such as RGBW? It would be great to have pixels more sensitive to UV and IR to get more interesting artistic color effects. I'm also considering going one step further in conversion and also converting to a monochrome separate camera. I read that by removing Bayer filter sensitivity can be increased especially in UV (microlens removal can reduce sensitivity but maybe it's so bad with newer pixel designs). But color information will be lost permanently. I saw that there are for sale laser damaged full frame camera's so I could take a risk to perform monochrome conversion. Can for example Sony A7III laser burned sensor be fixed after monochrome conversion?
