Have a newbie question to ask:
I noticed a speck of something (doesn't look like dust, more like a particle) inside the rear element of my tamron 18-270mm lens (the part that retracts during zooming).
I'm not sure if it affects my photos; have yet to test for that. What i understand is that dust/particles in the rear element will affect the photos taken as it is closer to the sensor.
Could you experts pls advise on how i can test to see if the particle is affecting my photos? I'm hoping i don't have to send the lens back to tamron for servicing..its only 1 month old!
Any of you guys have lenses with dust in the rear element but does not affect your photos?
Thanks in advance
