Panasonic's Lumix S1/S1R is a giant among mirrorless cameras

And by that we mean BIG.

Panasonic Lumix S1

The S1 and the S1R have the same body.

Big and heavy

The S1/S1R has one of the biggest and heaviest bodies among the full-frame mirrorless crowd -- the only one that's close is the Leica SL -- and is even larger and weightier than many competing DSLRs, such as the Nikon D850. The size is partly due to the sensor-shift stabilization mechanism, which can get pretty big with a full-frame sensor. It's not the mount, because the L-mount diameter (51.6mm) is smaller than both the Nikon Z (55mm) and Canon RF (54mm) mounts.

One of the reasons it's so deep is the hefty, comfortable grip.

24-105mm lens

One of the lenses that will be available at launch, and which is the kit offering, is a 24-105mm f4.

It retains a top status LCD like the G9, though the information is laid out a bit differently.

Dual card slots

The camera has two card slots, an XQD and SD. The XQD slot will be firmware upgradable to CFExpress at some point in the future.

High class viewfinder

In addition to the obvious differences on the outside -- a switch to a round eyepiece and a bayonet mount eyecup -- on the inside it's a lovely, bright OLED with a relatively high 5-megapixel resolution.

The back control design and layout is an updated version of the Lumix G9's, but the movie record button's been moved to what seems like an awkward location next to the viewfinder.

Joystick joy

The camera improves on the G9's joystick with the ability to navigate diagonally as well as horizontally and vertically.

Viewfinder bump

The viewfinder is also one reason the camera's taller than some.

The camera has a USB-C connection that supports charging and a full-size HDMI connector, as well as mic and headphone jacks.

Drive modes

It has the same drive mode dial as the G9, though the 6K and 4K burst photo modes have been relocated.

Mode dial

While it has essentially the same locking mode dial as the G9, Panasonic drops the Creative Control mode, which is less important on a pro model.

Operation lock

Panasonic finally adds a control to quickly lock and unlock the other controls on the body, rather than forcing you to go into the menus.

Custom setting access

Like the G9, the switch on the front of the S1/S1R provides quick access to saved custom settings.

Multiangle tilting LCD

Panasonic has always gone with the swing-out-and-twist variety of display, but for the S1/S1R it switches to the type of three-way multiangle tilting display that Pentax launched with its K-1.

While these three-way displays can be set to a lot more angles than traditional articulated ones, they always feel awkward and confusing to position. This one's no different.

Worth it

However, given the flexibility of positioning the display, it's usually worth the cumbersome movement.

Front buttons

The front buttons are differentiable by feel.

Battery grip

The optional grip only holds one extra battery.

I Got an Early Look at Intel's Glass Packaging Tech for Faster Chips
Rahul Manepalli, right, Intel's module engineering leader, shows a glass substrate panel before it's sliced into the small rectangles that will be bonded to the undersides of hundreds of test processors. The technology, shown here at Intel's CH8 facility in Chandler, Arizona, stands to improve performance and power consumption of advanced processors arriving later this decade. Glass substrates should permit physically larger processors comprised of several small "chiplets" for AI and data center work, but Intel expects they'll trickle down to PCs, too.
