First leaked image of this new super compact Kase 150mm f/5.6 REFLEX E-mount autofocus lens

What you see here is a truly unique lens! Thanks to its unique REFLEX design, it is the most compact 150 mm lens I have ever seen. It also supports full autofocus…which, in my opinion, is also a world first? Correct me if I am wrong.

Here are the know specs:

Kase 150mm f/5.6

• Full Frame
• Autofocus
• 67mm filter size
• AF/MF switch
• E-mount (probably Z and X mount coming to?)

Of course we all know that REFLEX lenses have inherently a slightly worse optical performance that lenses with a “regular” design. But int this case you might be willing to accept the compromise because no other lens gives you that reach in such a small size. Kase made a bunch of regular E-mount lenses and also some Reflex lenses you can find on those pages at Amazon and BHphoto.
