The meaning of ISO

DPReview tells usYou probably don’t know what ISO means – and that’s a problem to explain what ISO (sensitivity) mean in the world of digital photography, compared to film, and why it is different.

This brings us to the biggest problem with using a clumsy metaphor for film sensitivity as the way of setting image brightness in digital: it means we aren’t given the tools to optimally expose our sensors.

Digital photography cameras are built on film photography. While some things are similar, when it comes to the image capture, things are totally different leading to a design that is often suboptimal at best.

RIP Nikon 1

Not sure who remembers the Nikon 1 mirrorless ? DPReview informs us tgat Nikon just announced they discontinued the Nikon 1, without a surprise.

The move to kill off the Nikon 1 line shouldn’t come as a surprise. In addition to the rumors flying around, the newest camera in the lineup was launched more than three years ago on April 2, 2015.

In comparison, Canon EOS M seems to have more traction in the market place.

Despite rumors, Nikon still doesn’t have a mirrorless system to replace this. Will they?

Rumour: Canon full frame mirrorless

Canon Rumors has something about a rumoured Canon full frame mirrorless:

We have now confirmed from a couple of good sources that a full frame mirrorless camera is well into its development cycle, as the camera is being used by select Canon pro photographers.

Petapixel adds:

One of the biggest unanswered questions about Canon’s upcoming camera is whether it will feature a native EF lens mount. Allowing Canon photographers to seamlessly use their entire existing arsenal of Canon lenses would be a huge boon to the camera’s ability to disrupt the market.

I wrote previously whether a SLR mount on mirrorless would make sense?

The answer is a NO.

What I see, if that camera actually exists, is an EF-M mount for full frame, possibly compatible with the actual EF-M downward (full frame on APS-C) but not the other way due to coverage, similarly to the EF-S mount cameras, that can use EF mount lenses. Like for the EOS-M, I also see an adapter available for EF lenses.

Time will tell if that gets to be beyond a rumour. At this time I have no speculation about its specs.
