A patent showing new 85mm & 50mm designs has surfaced. Both an 85mm f/1.2 and an 85mm f/1.8 appear as well as a 50mm f/1.4 and a 100mm f/2.

An updated 85mm f/1.2L II has been mentioned as being under development for quite some time, and we’re all expecting a new 50mm lens, which is an oft rumored product.

IS Versions of the 50mm, 85mm & 135mm Coming? [CR1]

IS Versions of the 50mm, 85mm & 135mm Coming? [CR1]

More Non L IS Lenses
We’ve been told that Canon will announce at least 2 new non-L IS prime lenses in 2014. The two you can bank on are a 50mm f/1.8 IS and an 85mm f/2 IS (the source wasn’t totally sure on the aperture, but did say it would be slower than the current f/1.8). Both lenses should be announced some time in the first half of 2014. The replacement to the 50 was originally slated to come in 2013, but fell into the status of delayed like a bunch of other Canon lenses.

The other lens that was mentioned was an IS version of a 135mm lens. It was unknown whether or not the lens would be an “L”.

More to come…

A New 50 Coming Soon? [CR1]

A New 50 Coming Soon? [CR1]

EF 50 f/1.8 IS USM
We’re told that a new EF 50mm f/1.8 IS USM is ready for release, but may not happen until Q1 of 2014.

The lens would be in line with the new 24,28 & 35mm IS lenses. Pricing would be more than the current EF 50 f/1.4 USM it would be replacing. However, Canon has noticed that the pricing on the 3 mentioned lenses at launch was too high and lead to poor initial sales numbers. Since the lenses have been price dropped, they are selling better.

Canon EF 50 f/1.4 USM $299 (free shipping)

Review – Canon EF 50mm f/1.4

Review – Canon EF 50mm f/1.4

New review
Justin has completed his review of the old Canon EF 50mm f/1.4 USM. The lens is about 20 years old now, yet still finds its way into a lot of people’s camera bags.

It’s a good lens optically, the AF and reliability of the focus motor can be a bit of an issue. However, for a mere $400, it’s well worth the money.

Patent: Canon EF 50 f/1.8 IS

Patent: Canon EF 50 f/1.8 IS

Canon EF 50mm f/1.8 IS
A patent has show up showcasing an EF 50 f/1.8 IS lens. Could this be the replacement to the 50 f/1.4? We had heard about this lens existing last year. While some may desire a direct 1.4 replacement with IS, I think Canon may want some separation between the EF 50 f/1.2L and the next 50 in the lineup. We’ve also heard of a new EF 50 f/1.2L design being tested.

New fast primes
The often talked about 50 f/1.4 and 135 f/2 have appeared in a new patent this week. We’ve heard that a replacement to the 50 f/1.4 would come first. A new 135 f/2L is a desired lens if they put IS into the upgrade. We’ve also heard a new 85 f/1.2L with reduced weight and approved AF performance was also on the horizon.

Canon EF 50 f/1.4 IS in 2013 [CR2]

Canon EF 50 f/1.4 IS in 2013 [CR2]

More non-L primes coming
Expect to see a new EF 50 f/1.4 IS sometime in 2013. There have been variations of a replacement for the very old (1993) EF 50 f/1.4 and it sounds like a 1.4 IS variant is going to be the winner. We have also heard of an f/1.8 IS version existing. Don’t expect such a lens to be much less than the $800 that the EF 24 f/2.8 IS, EF 28 f/2.8 IS and EF 35 f/2 IS all approximately cost.

The EF 85 f/1.8 is also in the works with an IS version we’re told. I haven’t heard anything about the very good EF 100 f/2 getting a replacement.
