If you have to deal in using long exposures or image stacking, here’s a gizmo you might be interested in. The Flashpoint Wave Commander can control taking a long series of photographs. You get to specify how long to wait before taking the shots, the shot duration, how many shots, and the delay between shots.

You can see the plug-in cord for the camera. This part is what you can replace to fit other came...

There’s been a lot of talk about using crop sensor cameras for subjects that need that “effective focal length” increase, for distant subjects like birds. For example, a 600mm lens has an effective focal length of (600 X 1.5) or 900mm. This may be close to the truth if both the full-frame and the crop sensors have the same overall resolution, but what about an FX camera that has more resolution than the DX camera, like the D85...

Competitor #1: Sony XQD

I tried to look up the D850 camera shot buffer numbers on the internet. All over the map. Either terrible or stunning, depending on who you ask. Nikon claims it should have a 51 shot buffer with the settings I shoot with.

I felt compelled to conduct some testing of my own, using a couple of different memory card types, since I’m a natural born skeptic. The manufacturers of those memory cards seem to compl...

Sigma lets you program their “global vision” series of lenses with their USB dock. This includes the Sport, Art, and Contemporary lenses. One of the things you can program is which autofocus algorithm to use. You get three algorithms to choose from: “Fast AF Priority”, “Standard AF”, or “Smooth AF Priority”.

By assigning a different algorithm to different custom switches on the lens (C1 and C2), you can change your mind on the...

Sigma TC-1401 Teleconverter on their 70-200 f/2.8 Sport lens

You can see how tiny the Sigma TC-1401 teleconverter is. It’s only compatible with a few Sigma lenses, so be careful to do some research first to see if it will work for you. It won’t work on Nikkor lenses. Similarly, I don’t think the Nikon teleconverters will work on Sigmas; I haven’t tried it, but they warn against it. I didn't check to see the compatibility combin...

70-200 and Nikon D850, mounted on Arca-Swiss foot

The 70-200mm f/2.8 is one of the primary lenses that most professionals and serious amateurs have in their lens arsenals. The Sigma 70-200mm f/2.8 DG OS HSM Sport lens is Sigma's second major version of this lens, and the first of its kind in their "Sports" line.

The nomenclature for Sigma initials is as follows: DG means it's full-frame coverage. The OS means it supports op...

Adobe stopped updating the standalone versions of Lightroom long ago. A feature they added to their Creative Cloud version called “DeHaze” caused extreme feature envy for us cloudless users. Guess what? There’s a way to get this functionality in the standalone version of Lightroom after all.

There’s a free Lightroom plug-in you can get from here

It works with Lightroom version 6.1 through 6.14. The website also provides instru...

I will attempt to contain myself during this lens review, but it won’t be easy.  This lens is something special. Sigma had a really, really big challenge to try and beat the legendary Nikkor 14-24mm f/2.8 lens. They won, pure and simple.

My praise is primarily centered on the resolution measurements I conducted using the MTFMapper program. Simply amazing results.

I have to admit that this is an item I never thought I’d own.  Why in the world would you want to cover up your camera LCD screen? Number one: the sun.  Number two: video. Number three: no concerns about focus calibration fine-tuning.

I am a total infrared enthusiast. I use some IR filters that make exposures extend to a few minutes, so the only way I know what I’ve captured out in the field is by reviewing the shot on my...

Nikon made a design change that is perhaps the smartest thing they’ve done since 1959. Their new Z6 and Z7 cameras sport their new lens Z-mount with a 55mm throat diameter and 16mm “flange-focal” distance.

This design change wasn’t possible for Nikon until they made a camera that got rid of its flipping mirror. On a full-frame camera, the mirror rotates through an arc with a radius of about 35mm, and their F-mount lenses had to...
