Many years ago, I decided to migrate my photo library from Apple's now-defunct Aperture to Photos, so I could take advantage of Apple's iCloud Photo Library (don't worry, I still have three full complete local backups, plus a separate cloud backup besides Apple's iCloud originals).

One pain point is RAW support. As camera manufacturers add new models, their proprietary RAW codecs are updated, and software vendors like Apple, Adobe, and Microsoft have to update photo editing tools to work with the new camera models.

I don't envy them this task, but as Photos was Apple's official successor to Aperture (a pale shadow to be sure, but it has its merits as a semi-decent library organizer), they've generally done well supporting new camera models. The compatibility list for macOS Sonoma, iPadOS 17, and iOS 17 is a testament to that effort.

On April 8, there will be a Total Solar Eclipse covering an large swath of the US, offering hundreds of millions of people the opportunity to witness one of the most spectacular displays of our sun.

I wrote two blog posts about the recent 2017 eclipse, as well—check those out:

For this year, I was considering going all-in on a custom Raspberry-Pi-based solar tracking system, recording video and images... but Will Whang already built a custom solar imaging setup that would put anything I build to shame.

Today Raspberry Pi launched their new Global Shutter Camera.

Outwardly it is almost identical to the 12 Megapixel High Quality Camera, and like that camera it accepts C and CS mount lenses, or most anything else with the appropriate adapter.

But flipping it over reveals a black plastic cover over the back of the board that is not present on the HQ or M12 HQ Camera:

Raspberry Pi just announced their new Camera Module 3, which comes in four variations (standard and wide angle, normal and NoIR for infrared use), and costs $25 for the standard versions, and $35 for wide angle.

That's a step up from the older Camera Module 2, which cost $25 and only came in a 'standard' focal length.

I posted a video reviewing the Camera Module 3 on YouTube, and you can watch it here:

Raspberry Pi has two official camera modules: the 8 megapixel Pi Camera, and the 12 megapixel HQ Camera.

Third party camera solution provider ArduCam has supplemented the official cameras with a variety of options for all kinds of Pi-based projects. Just last year they introduced the first camera to bring autofocus to the Pi.

...and yet I just bought a 2nd one!

Overall, I enjoy using Sony's current top-end APS-C model for my video work and occasional photography. But there are a few things that feel boneheaded and out of place that you should be aware of:

ArduCam recently completed a successful crowdfunding campaign for a 16 megapixel Raspberry Pi camera with built-in autofocus.

The camera is on a board with the same footprint as the Pi Camera V2, but it has a Sony IMX519 image sensor with twice the resolution (16 Mpix vs 8 Mpix) and a larger image sensor (1/2.53" vs 1/4"), a slightly nicer lens, and the headline feature: a built-in autofocus motor.

Autofocus performance

Getting right into the meat of it: autofocus works, with some caveats.

First, the good. Autofocus is quick to acquire focus in many situations, especially in well-lit environments with one main subject. Using ArduCam's fork of libcamera-still or libcamera-vid, you only need to pass in --autofocus and the camera will snap into focus immediately.

Today I released a video about how—and why—I 3D Printed my Grandpa and put him on my bottle of ketchup. Watch it here.

I sculpted a bust of my Grandpa in high school, gave it to my grandparents, got it back after he died and my Grandma moved out of her house (I wrote a tribute to my 'Grandpa Charlie'), and I kept on moving it around my office because I didn't have room for it:

Grandpa by Jeff Geerling, terracotta, 2001.

I decided it had to go, but asked my extended family if anyone wanted the statue (thinking it would be sad to destroy it). One enterprising cousin suggested he could 'copy' the statue in smaller form using photogrammetry:

After seeing GreatScott's video on creating great 3D Printing timelapses, I knew I had to make better 3D Print timelapses using one of my DSLRs.

I had already tried using my pi-timelapse script with a Pi Zero W and the Camera Module v1 and v2, but the quality is just so-so, plus it's not synchronized with the 3D printer, therefore at least on the Ender 3 V2, the printed object goes all over the place:

What I wanted was a stable and sharp timelapse of the entire process with high enough resolution to use in HD videos I produce for my YouTube channel.

So how did I get it working with my old but trusty Nikon D700? Read on...

First let me be clear: I'm not, nor have I ever been, sponsored by Sony, Nikon or any other camera manufacturer, and all my photography gear has been purchased with my own money (usually used since I'm not made of money).

With that out of the way, after waffling on the decision for over a year, I'm selling all my Nikon FX DSLR camera gear, and switching to Sony's APS-C mirrorless camera system.

But why?

For me, there are two major reasons:
