I might be getting extremely paranoid about dust in lenses but ill ask anyway :P

Bought a new lens (as above) from Amazon, direct - not a reseller. Upon inspection just now to an artificial light source ive noticed that theres a dark speck or bright line ending with a blob inside of the lens depending on how viewed. It is longitudinal in shape ie. if viewed direct its arrow shaped/dot shaped. If viewed from an angle it is actually a very consistent bright line (refracting light perhaps?) that runs right down the length of the lens ie. from the lens mount end to the filter end and is clear/transparent in colour. Ive noticed another bright speck like this (however no dark blob at the end of this one) in the lens that is consistently round and very fine in shape also running from front to back, if viewing the lens at an angle. Cant seem to easily get pics of these at the angle showing it stretching from front to back but will upload a few that might show what i mean.

Perhaps its glue from construction? They are quite near the edge of the lens barrel and it seems that i probably wont notice it unless i have a full frame camera - if at all...

Could people with the 50 f1.4 pls have a look at theirs looking through the lens at say a flourecent tube or spot lamp at all angles to see if its just the way the lens is made?
 
Left angle - black speck in clear view

Right angle - you can just about see the refracted white line extending from the black blob

Right angle - Refracted line shown up as white at an extreme angle this line is 10 times longer

Any thoughts? Likely to return it in any case. Just a pain in the ass :bang:
 
I would return that use a tripod to take the macro shot and put a light behind it, also take a picture of a neutral background wide open to see if you can see it in the pic crop and blow up, as it's on the front element it should not show in pictures but that looks biggish,:eek:


sorry i can see screws if this is on the back glass it's a bit more of a problem, someone will correct me if i'm wrong deffo send it back


then send it back for replacement not repair
