Hi!

I am new in Sony community. I have a sony Alpha 7 since yesterday with a a 50/1.8 lens. Used with my Nikon 1j5 ( I want to sell it) with 10-30 lens, ( Equivalent on full frame with 27-80mm.   I did not imagine that with the 50 mm lens I shall not be able to make close-up photos (e. g. wild flowers), because the minimum distance of focalization is about half a meter, and the angle is wide. 

So I need a solution. 

1. My first idea it was extension tubes, or close up lenses. Can you recommend me such solutions , compatible with Sony E mount respectively with my 50mm Sony lens?

2. I have found on the net Kenko extension tubes. (Are there others, alternatives?). My question is about your experience with them. I have seen some old posts about incompatibility, AF not functional, a.s. o. What is the real situation, Your experience. 

Thanks a lot Attila
