My experience with Ffordes has been a bit hit and miss.
I got an MX from them a while ago with 50/1.7 lens. It was a little beaten and the seals were gunky but it worked. I also bought a 28/2.8 from them and it was OK but it was a bit dirty. No damage and a little cleaning with some alcohol prettied it up but I expected a cleaner lens. Both items were, in my opinion, below the condition they described. The pictures on their page are either non-existant or they are so small that you cannot make any judgement. Their grading system seems to be a bit random too. Normally lower graded stuff is cheaper but in a fair few cases, lower graded stuff is more expensive! Either they are hiding something in the description or mutiple people are grading items on their own arbitrary scale or they are just crazy. Anyway, good stuff can be had from them if you are careful but be sure to mail them and ask about condition and if possible detailed pictures.
I have not gotten anything from them recently because I find other sources so much better. Locally I can usually find stuff cheap. Either that or the bay (gotta be careful though
), and recently I have been scouring KEH. They seem like a good trusty outfit although I haven't commited to any purchases there yet.
