The good news is it looks like it will be available at a decent price. The better news – the announcement date could be just around the corner.
- Lens design: 6 elements in 5 groups
- Full-Frame lens
- Lens coating specifically optimized for digital cameras
- Stepping motor (STM)
- Full-time manual focus
- Total length: 39.3mm
- Weight: 160g
Judging by the photo it will also include a metal mount, but will lack Image Stabilization and a focus distance window.
This lens is has the same amount of elements and groups as the EF 50mm f/1.8 II it replaces, but weighs 30g more and is slightly shorter.
Two unknowns at the moment, other than the price, are the number of diaphragm blades and filter thread. I cannot confirm this right now, but I’ve heard that the new lens might feature a 49mm filter thread instead of 52mm on the old lens.
As for the blades, it will be interesting to see if this new model will continue using 5 blades as Canon’s previous model or if it will move to a 7-blade design like the Yongnuo 50mm f/1.8 lens.
The lens is said to be announced “soon”, so the blanks should be filled before too long.
