Hi all, I have a Sony A300 and the tamron 17-50mm f2.8 lens and i tried the T.V. remote trick to try to see the light and i turns out that i can see it but when i put the kit lens on (18-70 f3.5-5.6) with the IR filter all pics come out black so i was wondering if the lens makes a difference as to weather it will work or not??? 
Thanks
