Nikon 14-24 lens review from a Canon user

This is a review of the Nikon 14-24 f/2.8 lens from the point of view of a Canon user. However, Nikon users will find the sections about filters and focus shift of interest as well. Canon has many great lens offerings, but their area of weakness has long been the wide-angles. Both the two Canon […]

Alaska winter photography gear

For last winter’s trip to Alaska where I drove the Dalton Highway and photographed the Aurora Borealis, I didn’t pack light. I flew with two carry-on bags and two pieces of checked in luggage. In this post, I’ll discuss some of my equipment choices for that trip. Clothing I had a large assortment of hats […]

Using a rain deflector to photograph moonbows

Watching a moonbow with your own eyes is an awesome experience. While the camera can capture colors that the eye doesn’t see (as explained in my previous blog post about moonbows), the way it works doesn’t capture the experience that well. A long moonlit exposure looks almost the same as a daylight exposure that one […]

New images: Sequoias and stars, Kings Canyon NP

Although they are not as tall as the coastal redwoods, the giant sequoia trees still reach impressively into the sky. I found it difficult to convey the sense of cosmic height in daylight images. The usually blue sky isn’t visually that interesting, there are almost always harsh shadows or dappled light on a part of […]

Canon 70-200/2.8 IS II, 70-200/2.8 IS, and 70-200/4 IS: comparison/review

The short 70-200 tele-zoom is one of the most popular professional lenses. It covers a useful focal length range, good from portrait work to sports shooting and also for distant landscapes as well as details. Canon makes four of such lenses. All of them use a ring USM motor which offers fast, silent focus plus […]

New images: Green Sand Beach, Hawaii

For a change from working in the rain in Hawaii Volcanoes NP, I drove to South Point, the southern tip of the island of Hawaii. The access to Papakolea Beach consisted of a maze of badly rutted vehicle tracks, along the coast, alternatively sandy and rocky. A four wheel drive was definitively necessary. Hiking would […]

Best ISO for low noise on Canon 5D mk2

What ISO should you use for lowest noise ? Everybody knows that low ISO will result in lower noise and high ISO will result in higher noise. But is it a continuum, as one would intuitively think, or are some ISOs better than others ? In the past, I had seen advise to use only […]

Canon Wide Angle Zooms comparison/review: 16-35/f2.8 L II v. 17-40/f4 L

Canon makes two wide-angle zooms for full-frame cameras. Both are L-lenses, reasonably well-built, with fast USM autofocusing, a non-rotating front element, and an environmental rubber seal. The 17-40/f4L was introduced in 2003. The 16-35/f2.8 L II, released in 2007, replaced the 16-35/f2.8L of 2001, which itself replaced the 17-35/f2.8L of 1996. I have not used […]

Mac system re-install and software list

They say “it just works”. However, over the last month, my Apple computer just crashed. The symptom is a “kernel panic”, with a message over the frozen screen advising to hold the power button. This first happened a few times a week, and then worsened to several times a day. After two other support people, […]

Canon 24 TSE-II v 24 TSE, a comparative review

About a decade ago, I switched from Nikon to Canon. I was attracted, among other things, by the availability of a 24mm tilt and shift (T/S) lens, which brings to 35mm some of the controls available to the large format camera photographer. While it has served me well, its T/S functions making it possible to […]
