Despite white wall tests of the Canon EF 28mm and 135mm lenses showing acceptable levels of vignetting, my first real world use of them ended in failure.
Since buying this head, I've quickly learned to love it, especially after buying the necessary hardware that allows me to invert it as needed. The smooth design, reliability and light weight has helped it find a permanent home atop my Gitzo GT1542 Mountaineer tripod, supplanting the GH1382QD ball head that came with it.
There are some drawbacks though. Uncannily enough, they’re the same as with the Canon EF 28mm ƒ/1.8 USM: slight vignette with a hard vignette at infinity focus. At ƒ/8, it isn’t very prevalent as you’ll see in the samples, easily corrected with a 5:4 crop that retains 48MP. However, as the aperture gets smaller, the vignette hardens, as you can see at ƒ/32, but still works at a 5:4 crop ratio. The lens works fine with a 3:2 crop at full sensor width and in 35mm crop mode, so you can choose what works best for you. Weirdly, the lens changes focus as you move in and out of playback mode on the GFX...
Widening out to an approximate 22mm in 35mm format terms, the Canon EF 28mm ƒ/1.8 USM does show some hard vignetting that is never fully resolved. It’s very, very slight and occurs at ƒ/4 and smaller at infinity focus. Vignetting is prevalent fully open, mostly disappearing by ƒ/4 at close focus distances. If the vignetting is a problem for you, the EF 28mm ƒ/2.8 IS might be a better bet but isn’t on Canon’s list of preferred lenses for the 5DSR, so it may or may not resolve well on a 50MP sensor.
As soon as I realized how the upright on the Ellie interfered with my battery door, I was able to devise a cheap solution for manufacture: a small bracket that would accept the rails and to attach the upright with truncated rails, aka screws, forward of the current position. I proposed the question to @3leggedthing's Twitter account, only to get, "we can't design a specific bracket for every camera and configuration I'm afraid."
Here's one of the first things I do when I buy a new camera: Secure the screws that secure the tripod screw port on the bottom of your camera.
As I have alluded to in a burst of recent posts, I am planning to generate a small database of lenses for use on the Fujifilm GFX series. Here's my chance for an introduction to give my rationale and to lay the foundation of this endeavor. I'd like to break this down into three "Y's." Let's begin with a personal "why": I'm choosing to use Sigma lenses to obtain focal lengths and apertures not currently offered in the GF lens lineup. Fujifilm's lineup is sparse at best, and apertures wider than ƒ/2 aren't represented. It's not that I'm a bokeh whore; it's that I need more light gathering for astrophotography and Fujifilm's widest lens, a 23mm, has a maximum aperture of ƒ/4 and that's just not going to work without a star tracker due to the sensor's 51MP resolution. I'm hoping to print a few of these so what counts for "sharp" on the web doesn't work at 20" print sizes. Other benefits: 35mm lenses are much cheaper, especially used prices, and these lenses mostly have direct focusing units unlike the "fly by wire" systems used on Fujifilm lenses. The GFX system just isn't mature enough to have grown both a complete lens lineup or a diverse used lens market.
As I've made clear in a previous post, nobody makes the perfect bag. It's a fools errand because "perfect" is subjective and what works for one is completely inadequate for another. However, the more modular a bag is, the better chance for it to become all things to all people by allowing all people to adorn it with all things to meet their needs. Looking further into this idea, especially since Peak Design's recent release of a fully redesigned bag lineup dubbed "v2," I've realized Peak Design is great at making accessories that meet the needs of most people but wrap it all up in bags that don't. Take their 45L Travel Backpack... it converts into a duffel with a forward facing, wide-mouth, zip opening. It's really not great for anything but a duffel bag that turns into a half-assed backpack for longer distance carry, especially for outdoors. However, for camera carry within, they've created camera cubes with efficient padding, mindful access port placement, an abundance of attachment points and durable exterior skin sufficient enough to be used on its own. A quick check of the external dimensions gave me an idea as the camera cube is nearly spot on with the dimensions of Shimoda Designs' large Integrated Camera Unit (ICU) for Explore and Action X backpacks.
Usually, Kickstarter is a collection of scams and bad ideas for internet virgins to be separated from their money. Sometimes, if you know what you're doing, it's a source for good deals. In this case, Shimoda Designs has established itself as a reliable maker of durable, action oriented camera backpacks. Shimoda decided to use Kickstarter as a "group buy" for their new line of Action X backpacks and mine managed to arrive just after Xmas.
