Ever since Sony announced the 24mm, 40mm, and 50mm compact G lenses for their full frame cameras I noticed something familiar. Every one of them has a 49 mm filter thread and the same latching elements that my E 20mm f/2.8 APS-C has (the FE 28mm f/2 as well).
Today I got the chance to mount my VCL-ECU2 converter on the 24mm f/2.8 G. The pair doesn’t look that great. Perhaps the SEL075UWC wide angle converter is a better fit. Nevertheless, the adapter works. Because I was in a hurry, the image quality with the adapter isn’t that great. When I got back home, I noticed the front element of the converter had some noticeable smudges on it.
A 24mm lens will have a nearly 37mm field of view on an APS-C sensor. Adding the VCL-ECU2 adapter will get you a 27.5mm lens. If you’re a full frame user, you’ll get an 18mm field of view with the converter on.
Is this solution elegant? No. Does it defeat the 24mm’s purpose of being compact and lightweight? Absolutely. This are perhaps the reasons Sony isn’t advertising compatibility between these two items.
PS: I didn’t get to mount the converter on the 40mm and 50mm G lenses, but I’m sure the results would have been similar.
