Playing with the Sigma 50-100mm f1.8 Art Lens

I recently acquired a Sigma 50-100mm f1.8 zoom lens, part of the company’s Art lens series. At first blush, a 2x zoom ratio seems pretty limited, but two things set this Sigma apart from other zooms. The first is the optical quality, which is outstanding. The second is the f1.8 maximum aperture, which can be used throughout the zoom range. As others have noted, this lens effectively replaces several prime lenses, including 50mm, 85mm, and 100mm, plus anything in-between. This…Continue reading Playing with the Sigma 50-100mm f1.8 Art Lens

Whose Future Is It?

Who will shape the tech future? Which companies, NGOs, governmental organization, and other entities will shape how we use tech, view tech, and consume tech. The biggest impacts on daily lives may lie behind the scenes, not in our daily interactions. Eric and I have a spirited discussion about who will control and define the future of tech. Will it be old school companies like Microsoft and Apple, the new generation of Internet giants such as Google and Facebook, or…Continue reading Whose Future Is It?

Nikon D500 and the Quality of Noise

I’ve been shooting with the Nikon D500 long enough to become comfortable now, though I’m learning something new every time I shoot with it. I bought the D500 because I wanted to return to Nikon, and return to DX shooting, where I’d been most comfortable in the past. However, I also lusted after the low-light capability. The D500 natively supports ISO settings up to 51,200 and can be pushed to ISO 1,640,000. As you might imagine, anything shot at ISO…Continue reading Nikon D500 and the Quality of Noise

Eric’s Excellent VR PC Build, More Nikon, and Kublacon!

  Eric needed a new PC to run his spiffy HTC Vive VR kit, so we built one. The parts list impresses: Core i5 Skylake, GTX 980, 16GB DDR4. Eric, David Bryant, and I got together and tackled assembly chores. Along the way, we experience one of the worst case designs I’ve seen in a long time. The Bitfenix Prodigy micro-ATX case may look like its mini-ITX sibling, but it’s an abysmal design internally. Eric discovers PCPartpicker, a nifty tool…Continue reading Eric’s Excellent VR PC Build, More Nikon, and Kublacon!

The Endless Game Patching Cycle

Meaning Once upon a time, you’d update a game maybe once or twice in its lifetime. In the new, always-connected world, games are seemingly patched weekly. It’s annoying, but given the social nature of modern gaming, may be necessary? Or is it?  Getting into a game during our Friday night LAN parties can be a crapshoot. Sometimes we just fire up a game and play. More often, though, we either need to wait for a big update to install, or…Continue reading The Endless Game Patching Cycle

Going Home: the Nikon D500 DSLR

Welcome to Photography Week at Uncertainty. I’ve been writing about the cameras in my life for several months now, but decided to wrap up the series with two more camera stories, thoughts on photographic workflow, other photographic gear, and the new camera entering my life.  I’ve waxed a little poetic about the Nikon D300 I used for several years. So when Nikon announced the spiritual successor to the D500, I decided to return home. I’d been a Nikon user for…Continue reading Going Home: the Nikon D500 DSLR

Beyond Today’s VR Gear

Let’s take a break for photography for a day, though this topic is peripherally related, as we do mention VR cameras briefly. Oh, yeah, and my Nikon D500 should be in my hot little hands by the time this posts. So we’ve got a bit about photography in our Tools discussion. Meaning People are receiving their first wave units of the Oculus Rift and HTC Vive. But what’s next for virtual reality? Will the hype and interest hold on long…Continue reading Beyond Today’s VR Gear
