content: Recently I bought a Flir 30mm supplemental lens (15 degree) for my E40. I tried it and it worked great as expteced. I also tried mounting this lens in a reversed position, then I got a 1.7x wide-angle lens as well as a close-up lens! The images looks great! For temporary use, you can simply hold it in front of the camera. Save a lot of for a wide angle and a micro lens

content: I bought some FLUKE TELE1 and TELE2 supplemental lenses and found them to be optically similar to the Official FLIR supplemental TELE lens. At the time, the FLUKE supplemental lenses were being given away free with purchases of some of their cameras so I saw a few appear on eBay at good prices when owners did not need them. Sadly the FLUKE lens prices have risen since then, but decent deals do come up now and again. The joy of supplemental lenses is their versatility. They will work with many different brands of camera with just an adapter needed for mounting. Some thought is needed when wider angle primary lenses are involved though as vignetting can occur. These lenses work best on cameras that have a ~25 Degree HFOV and manual focus.Fraser

content: Hi Fraser, yes supplemental lenses are fun to play with.By the way, how about your Fluke adapter project going on? Are there any finalized 3D print models? I saw a new WIDE2 lens for a great price, but I'm not sure if I can handle the adapter .

content: Sadly the lens adapter project fell by the wayside due to other distractions. I will revisit it when able.The TELE2 and WIDE2 have a short bayonet mount and are more suited to an alternative mount than the TELE1 and WIDE1 that uses a sleeve bayonet mount that might need to be shortened for an adapter.Fraser

content: Hi Fraser, could you help identify this lens? Is it a supplemental lens or a standard lens? The bayonet mount looks like the TELE1 lens you posted. Do standard lens use such mount for Fluke camera? I can't find any official info about it, it looks like a 3-party lens made for Fluke camera.

content: That lens certainly looks like a 3rd party supplemental lens for a Fluke camera. There were companies that offered 3rd party supplemental lenses for thermal cameras. Torrey Pines Logic was such a company and I have one of their X2 supplemental lenses for my Raytheon/L3 Thermal Eye X series thermal observation scopes (X50, X100, X150 and X200).Fraser

content: I bought an unbranded supplemental lens at a good price recently but have yet to determine what camera it was intended to be used on. It is completely anonymous so I do not know who made it. Your mystery lens has the distinctive Fluke sleeve type bayonet mount so that provides a good clue to its intended host cameras identity.

content: Thanks for your reply Fraser, your lens seems quite big tooFrom the bayonet mount it looks similar to Fluke Tele1 instead of Tele2. I just want to make sure it is a supplement lens and can be used (with some adapters) for other cameras/scopes, just like Flir 30mm lens (not long enough). The seller ask about 210 dollars for this 76mm lens. I also look for Fluke Tele2 as you mentioned, but they are far more expensive right now.
