Just came back from Funan with a friend who was looking around for the FE55 as well.
As usual, Sony Stores are slower than the shops in Funan. He bought one set home after visiting many shops, but at same RRP.
Stocks are very limited, so no chance to bargain. If you don't want it at RRP, the next buyer is just behind you waiting.
The Sony Stores are supposed to have their stocks ready on 29 Jan (if no delays again), but it will just be enough for people who pre-ordered from them.
I guess the price will stay at RRP for quite some time. If you already have other lenses to shoot, perhaps you should wait for healthy stocks when you test out the lens first from friends who have it.
Some users like it, some don't - that explains why a few 55FE was sold over the past few weeks at BNS.
Personal opinion. It is a little harder to shoot accurately due to the thin dof, if you shoot at F1.8. Also, the 55mm does not have OOS, but the longer focal length is more difficult to shoot than the 35mm FE, especially on a A7R. Discussed quite widely in the forums, and you can do a quick search.
Also, though 55FE is a sharp lens like the 35FE, but some may not like the modern look, which some described it as "predictable" and boring. Not like those classic lenses that many bros here are using, with unique bokeh qualities.
I guess we should be seeing more 55FE in the BNS not long after the usual initial impulsive buy/queue, so if you are not in a rush, wait patiently at the BNS threads!
