If your shots were of landscapes, you are probably okay due to depth of field. If you were working at closer distances, you may have problems.
Thanks for the info, it was mostly landscapes, on my Maniya 7 and 43mm lens but still, kind if lane there's a significant travel distance from infinity to "infrared infinity" blah wish I had known... Well I'll find out Friday...
