First Clips With The Dog Schidt Flare Factory 58

After much anticipation, my new Flare Factory (FF) 58 lens from Dog Schidt Optiks, aka Rich Gale, arrived today. I was on a photo assignment when the lens arrived via FedEx (ahead of schedule, I might add – bonus), and when my girlfriend told me over the phone that she had just signed for the delivery, I rushed home and tore open the box (which looked like an elephant had stepped on it — thanks FedEx). Luckily, the lens was very well encased in bubble wrap, and was in great shape. If you don’t know what the FF 58 is, it’s pretty simple. Dog Schidt takes old Russian Helios -44 58mm f/2 lenses, and “reworks” them to have certain characteristics, which you can specify for your custom-built lens. It’s pretty cool. Check out Dog Schidt’s Facebook page to see all the cool stuff you can order up on a FF 58. I ordered mine with cleaning marks (for extra rainbow flares), a normal-prominence blue tint, and a fixed f/2.8 elliptical aperture, to simulate the elliptical bokeh of an anamorphic lens.

After walking in the door after my assignment, I immediately slapped the FF 58 on my D800 and stepped into the yard to bother my dogs and shoot the sun in the trees.  One specific reason I bought the FF 58 is to help simulate a film look, because that’s how I like to shoot. In accordance with that desired workflow, the following clips have been lightly-graded and grained up with FilmConvert. Here’s a two-minute sample of the characteristics of my particular Flare Factory lens:

Just One Reason Why I Love Zeiss Glass

I love lenses. I mean, I really love lenses. If I had not already invested twenty years in a professional photo and video career, and building a client base to support such a foolish endeavor, then I would love to have been a lens tech or an optical designer instead. The act of holding and using fine glass brings sincere joy to me. And this video from Carl Zeiss is a fantastic illustration of just one of the many reasons why Zeiss has been my Objektiv of choice for so many years. Such passion for quality of design means that I have more power to exercise my own passion for image excellence. I’m very-much looking forward to visiting the Zeiss booth at NAB in two weeks!

An Inexpensive Cine Zoom for the AF100?

A few months before getting my AF100, I started testing various C-Mount lenses on my GF1, because I knew that [economical] modern cine-style zoom lens options on a Micro 4/3 video camera were going to be somewhat rare. An old TV-C lens can be had really cheap, and I thought that there might be one or two 1″ lenses that wouldn’t vignette too much on the 4/3″ sensor.

Canon TV-16 25-100mm f/1.8 Zoom Lens
Canon TV-16 25-100mm f/1.8 Zoom Lens

I started with a 16-160 f/1.6 Tokina CCTV zoom, which is a tank of a lens. I was really praying that it would work, because I would love to have a 10X f/1.6 lens to play with. I also picked up a Fujinon TV zoom and a Canon TV-16 zoom. As I suspected, the Tokina and Fujinon lenses vignetted very badly, but the Canon actually wasn’t too bad. It vignettes, but I can see how that in some shooting situations, it could be usable. In the mid zoom range, the black edge comes inside of the frame in the corners, but it isn’t as pronounced in the wide and tele positions. It’s there, but it doesn’t punch you in the face; it’s more of a gentle slap. Either way, it still stings a bit. I will post some real-world clips from it soon.

I think that if I could enlarge the image circle 1.4X, the problem would be corrected. I could handle losing the stop of light, but that would mean it would become a 70-280mm (FF 35 equiv). I don’t really want a zoom that long on the wide end. I may have to relegate the Canon to being a special occasion lens.

I’ve seen mods to mount a B4 2/3″ servo lens onto the AF100. That seems a sound option, especially if you get one of the lenses that has the built-in teleconverter because it solves your image circle problem right off the bat. 2/3″ lenses are wider, which allows more general use after magnification.

Another solution is Abel CineTech’s HDX2 adapter, which is an optical B4 to PL adapter that enlarges the lens image circle from 11mm to 22mm (soaking up two stops of light in the process), and also corrects the 3xCCD optics to project for a single sensor. But, at MSRP US$5500.00, it’s hardly the economical option for low-budget users. On the other hand, if it allows a $15,000.00 servo lens to become usable on larger format cameras, I can easily see how it can earn its keep in a production environment.

So, my search continues. If anyone knows of a C-Mount lens that will actually cover a 4/3″ sensor, please let me know!
