content: Hello,I have a FLIR E30(same as E40/E50/E60 for the purpose of this question) that I want to swap the factory lens with a 45 degree lens (http://store.flir.com/product/ir-lens-f-10mm-45-degree/t-series-accessories).How would I go about removing the stock lens and installing the new lens ? I've looked through E30 the manual but it's not mentioned. I don't have the 45 lens manual.Thanks

content: See the attachments below. I didn't have a 45° lens to hand, so I used our 6° one - it looks hilarious! Same principle though.

content: Just for the sake of completeness... E60 mating with a 45° lens.Chanc3 might forgot to tell you about the trick with the protective cap of the lens:Take the protective cover from the back of the lensMate the nipples of the cover with the dimples in the plate on the cameraTwist it 45° CCWThe cover is loose nowGet the lens aligned with the white dotsTwist it 45° CWFinished!Don't forget to activate the calibration for the lens in the menu. Unfortunately the EXX does not use the contacts of the lens.

content: Asked this on a new topic already when I found this thread:I've been experimenting with the 45 degree wide angle add on lens on my E30 and was wondering how big the differences in temperature measurements (thermal gradient) would be due to the additional lenses.So I tried certain reference measurements with and without the add on lens but without setting the camera configuration for this add on lens, because it seems to have no valid calibration anyway.To my surprise I could not find any difference in any temperature reading (tried between 0-300 degrees Celsius), neither in the center nor in the outer frame of the picture.Anybody else having an explanation because I was expecting at least a slight difference here?CheersHikanio
