New 50′s on the block?
Received word today that prototype 50 f/1.4 II’s and 50 f/1.8 III’s exist. The thought was both would be announced at the same time.

The 50 1.4 is in dire need of an update, and I think you could expect to pay twice as much for one than the current model.

No mention of IS in either lens.

Nikon has updated both lenses, so this one seems plausible. I’ve given up posting when such stuff would be announced. No one can truly know.

A much needed upgrade is coming
A good source piped up today and said a new EF 50mm f/1.4 USM exists and is being tested. Release date is unknown.


  • Optical upgrade, but it’s not “L”
  • Build upgrade. The current 50 f/1.4 from Canon is one of the most unreliable in the lineup.
  • New USM

Along with the above, expect a nice price increase as well. Most likely above its Sigma counterpart.
