“In 2017 we introduced a rear mount filter system for the Canon EF 11-24mm F4L USM: The Aurora Aperture CR format, an industry-first rear mount glass filter,” said Jeff Chen, founder, and CEO of Aurora Aperture Inc. “The next generation rear mount filter system is a major upgrade from the CR format filter system. It expands supported lenses to several other popular ultra-wide-angle lenses, at the same time adds more filter choices. More importantly, the new...

Not the 16-35 f/2.8 III and not the f/4.0 :( ?!

And also not the Sigma 12-24 f/4.0?

But I love the idea! Would be perfect if this would fit on each lense tho!

Hi!

Why not Canon ES 16-35/4? That lens already has a 77mm filter thread and most users already have a set of 77mm filters. So I assume that the market for that lens is simply too small.

Light pollution filter? That will be a Neodymium/Redhancer/Clear night/... filter in this case. They only work against sodium vapour light (which are more and more replaced by LED), they also reduce some other parts of the spectrum without light pollution and they double the exposure time. Removal of light pollution for astro is best done in post processing and the effect of this filter for normal night photography can also be emulated in post processing. Keep your money for something useful!

Considering how sensitive my 11-24 is to rear element dust showing up in images I am not enthusiastic about adding two more surfaces to increase my misery.
The risk of dust on the rear lens was the reason why Hasselblad produced their SWC (super wide) with a fixed Zeiss 38 mm 6 x 6. wide angle lens.

This is interesting. I wonder how much this degrades the IQ? When the lens manufacturer does this, as Canon does with several long lenses, and their EF to R adapter, they take optics into account, and rarely use glass filters because of the degradation. Unless, that is, they include a clear, coated glass for when there is no filter being used (preferably fron the lens manufacturer) so that it”s part of the calculated optical system.

Not a product for my kit.

I can understand the idea behind it, but when I want to make serious nature photog with WA/UWA lenses my most important filter would be a graduated ND where I can decide the level of the horizon by shifting it in my filter holder. Try to do so with a rear mount filter system :rolleyes:

Luckily they don't offer a CPL for it. That would have made it bonkers :ROFLMAO:
