Over the past year or more, in anticipation of this time–where Nikon, Canon and everyone else would jump on the mirrorless train–I have been testing out and thinking a lot–too much really–about the equipment I use and what the future holds. It has been clear for a while now, at least to me, that mirrorless...
A little over a decade ago, I wrote an article in my Fall 2007 Newsletter, entitled Digital Photography: Where do we go from here?, which discussed improvements I was hoping for in upcoming camera announcements. To be sure, there have been some incredible advancements in both DSLRs and mirrorless cameras over the last decade. Owning...
Hi Michael,
Thanks for sharing your thoughts about the Mirrorless world.
Since Nikon and Canon entered the full frame Mirrorless focusing most of their marketing on the lens mount itself I have been wondering what are the advantages of having a bigger diameter mount like Nikon vs the Sony smaller mount diameter.
In 1987 Canon introduced the EF mount with a much bigger diameter than Nikon and Nikon was still able to build awesome lenses on pair with Canon.
Do you know what are the advantages of the bigger diameter lens mount?
Cheers
Martim – Hello. There are quite a few benefits to a larger lens mount, and especially with such a short flange distance like the Z series Nikons and R series Canons. First it simplifies the lens design pretty seriously, allowing lenses to be built with fewer elements, which means more light reaches the sensor (i.e. fewer lens surface interfaces). Second, you can also collimate the light so it is striking the sensor straight on instead of being bent at radical angles. This reduces Chromatic Aberration and also allows for much sharper rendering in the corners than previously. Thirds, it allows for using IBIS to it’s full potential. Fourth, in the case of the Nikon, it might mean that we are using the center of the lens more – i.e. the best part of the optics. With the Z7 I have not really seen any CA at all, which is pretty phenomenal. I will discuss this more in my actual review. This covers the basics of a larger lens mount. I am sure there is a lot I don’t know. Nikon released a very extensive PDF all about the reasoning behind the larger lens mount.

Excellent thoughts about mirrorless Michael! I totally agree that the future will be (or should be) a range of mirrorless cameras incorporating the advantages and minimizing the disadvantages of mirrorless. I’m very pleased with the Z7, but already thinking about a Z850 :-).
Many Thanks for the article. As a long-time (mostly) Leica user I am clearly not in the telephoto or ‘need for speed’ lane. As such, I now cannot imagine having to use those big, long-lens units of my youth! (Especially as most Leica lenses are basically miniaturized.)
At Photokina a few weeks ago the crowds of people around the mirrorless stands were many bodies deep. Probably 75% of them were carrying DSLR cameras so it was possible to see, first-hand, the enormous interest in mirrorless. I did persevere and got to fondle the Nikon Z7. Very nice!
