September 13 2009


Time for a random thought, because I have nothing else to offer at the moment; Sony has this Macro light adaptor in their catalog now.  It’s purpose being so you can use the Sony DT 50mm F/1.8 SAM or Sony DT 30mm F/2.8 Macro SAM lenses with the macro ring light, (not the twin flash lights).   I see a concern right off.  If you look at the dimensions of this adaptor, and the close focus distance of the 30mm macro lens, it seems there may not be enough room to illuminate the area closest to the lens when utilizing the largest reproduction rate, or full 1:1 macro of the lens.  Common sense tells us the close focus (extension) lens-to-subject distance will be around 1″ (25mm).   By looking at the left mock-up image below, It doesn’t look like it offers enough room.  I guess we’ll see shortly.  Obviously the 50mm F/1.8 SAM will have plenty of room.  This item goes on sale 11/30 for a retail price of $80–ripoff, (sorry, but it’s just a piece of plastic!)  Also, the A850 is in stock with an estimated ship date of 9/20, so says the website, B&H photo shows October for shipping.
