Brightin Star 10mm F 5.6 Pro Fisheye

By the time you read this, I will have already purchased, and lightly tested, both of the a Brightin Star fisheye lenses. I took out the Pro Fisheye because of the adjustable aperture, just to see how the lens would perform. I used my first Fuji mount fisheye, a Pergear, and enjoyed using it. After getting past the silly distortion of my facial features being distorted by the lens, I decided to take the lens seriously and try to find some happy compromise between the uniquely wide angle of the lens, and the uncorrected circular distortion.

Note: Contrary to some of the online evaluations, the lens aperture ring does have clicks, but they are soft and only at the full stops.

I took the 10mm F 5.6 Pro model lens, mounted on a Fuji X-E2 body, with me on a walk along the Sausalito shoreline. I parked beside the San Francisco Bay Model, as its location allows me to walk past a variety of boats at rest in their slips.
Doors to the San Francisco Bay Model in Sausalito. The windows are indeed round.

This photo is the entrance to the San Francisco Bay Model in Sausalito. I tried to position the doors as close to the center as possible, and did my best to keep the camera level. From an exposure perspective, the photo is "out of bounds", but the I believe the placement of the round windows so close to the center of the photo creates an interesting juxtaposition for a fisheye lens.

This cute little sign has a circular graphic that when centered, gave me a fairly normal looking image. The placement of the horizon line minimizes the distortion, while the randomness of the foliage on the right minimizes the visual impact of the edge distortion.

Post Production Corrections: One could say that a fisheye lens is just a wide angle lens with under corrected barrel distortion. It follows that some post production software can correct these errors. In Elements  I used the Spherize Tool to see if any meaningful correction could be applied. I was able to pull the "bulge" in slightly, and render the vertical edges of the sign a little straighter. With no discernable reference points on the left and right thirds of the frame. the finished rendition doesn't shout "fisheye" but could pass as a conventional wide angle lens photo. That is much more grief than I care to endure, as I could just as easily installed a conventional 10mm wide angle lens.

Blue Sky Exposure: In earlier posts about the fixed aperture Brightin Fisheye, I  had complained that the fixed aperture setting of F 5.6 wouldn't be small enough to provide some outdoor flash capabilities with the Fuji camera bodies I favor. I made three blue sky exposures with the highest possible synchronization setting for an X-E2 body (1/250 second).

Based on these three test shots, I could basically set my lens to F 8.0, my ISO to 100, and my shutter speed at 1/250 of a second and get a very nice blue sky. Not ideal for recording fluffy clouds, but the information is useful.
Sun Stars: This flag photo was made with an emphasis on the sky and letting the flag exposure go along for the ride. I was surprised by how nice the sun star turned out. If I had an important subject in the near foreground, I could have used a flash providing it was close enough to me, and that the light falloff wouldn't be objectionable. This is probably the only time that the "sun star", the effected created by the aperture design, held any interest for me.
I noticed this mural painted on a retaining wall behind a smog station located in the Castro. While the damaged sofa seems totally appropriate for the mural, the tableau seems out of place in the Castro. I was attracted to the comic detail of the cars, especially the Volkswagen station wagon with the old-fashioned room skylights. The camera was set to Aperture Priority, with1/3 F stop underexposed. I purposely cropped the right edge of the frame to minimize the presence of the pile of boxes at the left edge. There is not significant detail on the left edge of the frame.

My observations beg the question: Why use a fisheye? Nearly all of these shots could have been replicated with a 10mm rectilinear (non-fisheye) lens. I suspect that because the lenses are essentially zone focused (focus set my distance), it frees me to concentrate on the unique perspective the lens provides. Fisheye lenses require an appreciation for the roles the frame's left and right thirds play (or don't play) in keeping the viewer's attention at the center of the frame. That can be challenging, and for the moment, that's reason enough.

Fisheye Double Take

Pergear (Brighten Star) lens. I bought mine here.
For whatever reason, I seem to be behind in the times when it comes to what's new in    photo equipment. Granted, I am quite content with "living within" the capabilities of my existing equipment, and only when I am confronted with some new challenge will I be motivated to look for, and possibly purchase, some new piece of equipment. Lately I've been giving away seldom used pieces of kit when they become at best irrelevant, or at worst, boring.

In an earlier post I replaced my older Peargear 10mm F 8.0 pancake fisheye lens with a Brighten Star (a.k.a.Pergear)  10mm F 5.6, fully aware that there were some features I was less than pleased with. As I mentioned, I considered the change from F 8.0 to F 5.6 would make it more difficult to control my "blue sky exposure" to obtain the interesting skies I prefer as my background.

Now I will be the first to admit that I didn't stop looking just because I purchased that lens. I knew it wasn't the perfect solution to all of the exposure problems that I encounter, but was intrigued by the challenge of making it work in challenging situations.

My wandering eye fell upon another Brightin Star fisheye lens. It was a 10mm F 5.6 lens, specifications identical to those of the pancake lens I just purchased. I  noticed that this lens replaced the petal lens hood with two rectangular "wings". On closer examination, I saw some real innovation in the design. I liked that there were separate distance scale in both feet and meters. I'm sure the extended focusing knob would make it easier to select the proper distance setting. The icing on the cake is the placement: Both scales are visible when viewed from above. Closer examination shows multiple aperture settings ranging from a wide-open F 5.6 to a minimum aperture setting of F 22.

As you can see from this photo of the chrome variant, both  scales are visible when viewed from above. As I wear progressive bifocals, I can appreciate that I wouldn't have to squint at both scales being crowded into a tiny viewing window. I wonder if anybody will see fit to adding this twin-scale configuration to a lens more suited for casual street photography. It would certainly get my attention.

I have to admit, based on features alone, I must own this lens. I'm going test the first Perger/Brightin Star lens first to see how it performs. If it passes some basic sharpness tests, the innovative Pro version will be on its way.
