I've posted about my 305mm f4.5 Ross Xpres on here before but not about its coating. I assumed it wasn't coated but someone has posted one on fleabay, exact same lens, with lower serial number say it is coated.
Serial Number of my lens is 244752.
Link to competitors lens on fleabay is here: http://www.ebay.com.au/itm/ROSS-LOND...ht_1574wt_1028
BTW, I am in the process of selling it to upgrade other equip't, this may make a difference.
Photos attached.
The very front element has a 3mm transparent mark I took to be a bubble on the outside of the glass, but I'm not so sure now. It is an oblong shape, if you run a finger over it there is a very fine even depth indentation, like a small piece of film has come off, is this an indication of coating?
