Here's my annual picks of the 20 most interesting cameras I've seen in 2015. These are neither the best nor the worst products I've encountered, nor have I gotten to test some of them yet. They're simply all notable for their contributions, for good or ill, to making cameras fun to cover this year.
I really like the photo quality and feature set of the G7 X, and the G5 X adds back the exact features that are important for enthusiasts, including the hot shoe, grip and EVF, plus a wired remote release jack. I'm still in the middle of testing this one, though, and can tell you it's as disappointingly slow as the G7 X.
Studio dSLRs are getting squeezed from above as prices drop on medium-format cameras with their large, high-resolution sensors: Pentax's 645D is down to less than $4,000. Canon has fought back with the highest-resolution full-frame sensor to date, a 50MP version that it's put into its 5DS and 5DS R dSLRs, which cost about the same as the Pentax.
Canon's Rebel line of entry-to-midrange dSLRs has always had a relatively cheap feel. So this year, the company split its top consumer model into two versions: the conventional T6i/750D and the T6s/760D, which has a better build quality and a few higher-end features.
While there's nothing exceptionally notable about the M3 itself, its existence in the US is. Canon chose to reenter the US market in October with its top-end interchangeable-lens model after meeting a "meh" reaction to its original EOS M in 2013.
Instead of attempting to improve on the photo quality of the iPhone as many have tried, DxO just decided to replace the camera altogether. And it did so with a very cleverly designed module that plugs in via the Lightning connector.
It's priced like a Leica, but the Leica SL is one of the company's recent attempts to produce a more mainstream camera (not including the series of Panasonic clones); in this case, one to compete with the Sony A7R II. That means it had to included several un-Leica-like features, including a built-in electronic viewfinder.
While it uses a similar soda-can design to Sony's QX1, the interchangeable-lens camera you strap to your phone, Olympus at least took the A01 a step further and open-sourced the hardware and software for your DIY pleasure.
Sony keeps cramming more into its compact RX100 series of cameras; in this case, Sony expanded its capabilities with a lot of useful video options and 4K recording. It's also one of the two Sony cameras that launched the company's stacked CMOS sensor.
