I am a keen infrared image maker and recently jumped ship from Canon to Sony. One of the reasons for this was the access to full frame mirrorless as I love my wide angle lenses for infrared.
The problem is that I am having trouble finding suitable full frame lenses suitable for IR as most of the Sony lenses have "hotspots". I have tested a few lwnses and visited most "infrared" knowledge articles on the web based around camera company modifiers and infrared groups. The list of suitable Sony lenses seems quite limited so I have started experimenting with other brands and adapters.
Is there anyone else out there in infrared world that we can discuss what we have learnt? May even try and post a list of lenses but this will take time and money to test and develop.
To see some infrared images visit my infrascapes gallery at - http://markd.photography/markd/digartal-colour-places/ , although most of these are pre Sony but the gallery will expand as I have 3 Sony Aphas and 2 are infrared.
Thanks.
Mark
