I have heard a lot of good stuff on them however I had an odd experience when I enquired about a Zeiss 50mm they had for sale - used.
It was listed at around £449 - £499 from what I recall and I called them to ask on the condition one Saturday morning. I was promised a call back upon someone getting it out of display to give more of a description however didn't hear anything. Tried calling back and got no answer so emailed, again no response either over the weekend.
I had a phone call Monday from a lady who told me that for some reason it's now no longer available and has dropped off the system.
I checked there website a little bit later in the day and it was still listed in the same place, although now at a price of £699. They are only £599 new so what this is all about I don't know however something didn't feel right to me. I ended up giving my money to Ffordes in the end.
This is probably a one off, a lot of people do rate them quite hightly and to speak to they seemed very pleasant. I just found my experience a little odd.
