Adapting GFX: Canon EF 135mm ƒ/2L USM

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...

Adapting GFX: Sigma Doesn’t Seem to Be the Answer

After spending a few weeks with the Sigma 50mm ƒ/1.4 Art, I've come to realize maybe Sigma lenses aren't the solution for me. At least the 50mm has a very short focus throw, making manual focus a tedious process, even with focus aids like focus peaking and focus zoom. Autofocus is just too unreliable and slow to depend on for all occasions, making manual focus capability a priority.

Sometimes You Just Have to Go a Different Direction

As much as I like Gitzo as a brand and the quality of their products, some of their stuff just isn't as good as others. Take for example their leveling base; Gitzo features a large lever for tightening a head to the base and a handle borrowed directly from their sister Manfrotto's lineup. Instead, I got the series 3 leveling base from Really Right Stuff. It's lighter, has a simpler attachment system with no silly lever and a much sleeker locking handle with, get this, a gear hook! That hook alone is almost priceless, allowing me to attach weight for stability when I'm not leveling the head, ending any need to swap back to the flat top base. Back into the box that can go.

New Toy: Arca-Swiss P0 Ball Head

Some first impressions after picking up an Arca-Swiss P0 Ball Head recently. Why? It's interesting. It's an inverted design so that the panoramic base is above the ball, ensuring a level platform for panoramic photography. Basically it eliminates the need for a leveling base. Combined with the 9oz weight, it'll reduce as much as 1.5lbs from my systematic tripod setup. I quickly discovered the reason for the weight savings: the base of the ball head is made of polycarbonate, most likely Delrin. The rest is made from either magnesium or aluminum, depending on the part. Regarding the design, it also has no protruding parts beyond the pano lock lever. The ball lock is performed by a rotating collar around the middle of the body, resulting in a sleek design. The ball is also aspherical, a feature used across Arca-Swiss' whole line, that increases friction to prevent your camera from loosely flopping over when the ball lock is loosened. A very elegant solution to a universal issue with all ball heads.

Wine Country Camera Filters: Screw-On versus 100mm

Very simply: Does Wine Country Camera actually use the same glass and coatings between their filters? I wanted my filters to produce the same results between my filter sets to reduce post-processing time. Recently, I replaced my B+W and Haida ND filters with WCC because the results between the two would cause difficulties in post as I'd work to match the output if I used both during the same shoot.

Gear Review: SunwayFoto T1A20D Mini Tripod

After the trip to Forks, I realized I needed a mini tripod for those times when I forget my full or travel sized tripod. One that's small enough to carry all of the time and when height isn't all that important compared to just getting the shot. This is one of those things I'll be throwing into the bag whenever I may encounter low light, ensuring I can use whatever shutter speed I need to get proper exposure without fear of instability.

Tripod and Ball Head Maintenance: Lubricants

Cleaning and lubricating your tripod, no matter what material it's made of, will extend its life. The biggest point of contention seems to be over lubrication, so here's where I'm going to attempt giving a definitive answer for most tripods and ball heads.

New ND Filters: Switching from B+W to Wine Country Camera

Despite owning, and being quite satisfied with, my Formatt-Hitech Firecrest 100mm filter holder kit, I also like to keep a 77mm ND filter set for lightweight carry. The B+W set I previously used worked fine but had a noticeable magenta color cast that was especially evident in the 10-stop ND filter. I recently decided to give Wine Country Camera's filters a try based on endless reviews touting their well controlled color cast. Should these work out well, I'll probably switch my 100mm ND filters out for WCC.

New Tripod, Revisited. Leofoto LN-324C.

As promised in my previous blog post, I'm revisiting my thoughts on the Leofoto LN-324C Systematic Carbon Fiber tripod I picked up before going to Forks, WA. The trip gave me my first chance to use the tripod in a real world setting for photos I cared about. After putting the Leofoto LN-324C and LH-40 ball head through the roughest conditions I ever plan to use it in, it has stood up admirably. There are no conditions to this conclusion. It is an excellent tripod, full stop. The value oriented pricing only makes this combo that much more appealing.
