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.
Out of the box, the Leofoto LN-324C made for an intimidating presence. Fully extended, it was clearly as tall as advertised and the weight seemed about right. Looking more closely, all the details looked right. Tearing it down exposed finely machined parts all around and a carbon weave that didn't betray it's "10 layer" claim; the weave was consistent throughout with no waviness or warping of threads and no pitting or cracks in the resin. All of the aluminum bits are finely milled with no tooling marks. Parts that may have originally been cast were finely machined to remove any casting seams and cuts into it were obviously milled. The anodizing is consistent all around and all of the included optional hardware is of similar quality. No flashes, splinters or metal shavings anywhere. Metal on metal contact points showed evidence of lubrication and glided through their movements smoothly.
The first three were taken before the penumbra even reached the moon. The weather had just begun to clear but a few clouds still managed to cross the sky before clearing moments before the Earth's penumbra began to cast itself upon the moon's surface. The full moon's glow and reflection on the passing clouds created an eerie look that was just too good to not photograph. All three were bracketed shots but the second is an HDR stacked in Lightroom. The first and third were fully recoverable from single images at the proper exposure.
went to Suncadia to take a week off from the city. being out near Cle Elum, it was also a chance to escape the light pollution of western Washington and attempt to capture the Milky Way Galaxy now that it's mostly above the horizon at my latitude. while I have ultra-wide lenses and fast lenses, I have not one that's both, so I chose to use the ultra-wide lens for increased opportunities for composition since I was shooting from a gap in the woods.
