The anamorphic lens 1.33x 50 of SLR Magic.
The pancake is pleasantly short and together with the quite substantial anamorphic attachment lens of SLR Magic acts both on my Canon 5D Mark III then again more like a single lens. The 35mm f / 2.0 with IS unfortunately proved to a wide angle for the anamorphic lens on small image sensor of the 5D (black corners!), But it produces the 40mm pancake and between anamorphic camera and a spectacular knack sharp widescreen. Great cinema at a bargain price a SLR!
Even in photos makes the combination a little ago. Instead piece together panoramas from individual photos and to resent the transitions, I adapt now simply Seitenverhälnis and get perfect widescreen views.
So if you wonder, where exactly is the meaning of such Pancakes is: There are just always use scenarios, has not thought of himself the manufacturer. Especially in combination with the anamorphic simply a dream couple, because the pleasing short distance between the rear lens of the anamorphic lens and the front lens of Pancakes evidently greatly help the process exhaust the optical properties of the anamorphic lens.
It would be desirable in fact only an image stabilizer, as well as IS is not a panacea and that the optical combination otherwise fits perfectly, I can not complain really. Older, manual M42 lenses were simply not nearly to the brilliance and sharpness of this absurd tiny 40mm Pancakes zoom and although f / 2.8 is now no drama, you get here just already from open aperture tack-sharp results with f / 2.8 maximum aperture for video then already is quite courageous, because you tend to already has a very short and thus correspondingly difficult to control depth of field. Instead, therefore, currently tend overpriced M42 may fuss around waste glass it just sometimes modern glass for special purposes be. It simply makes the combination and there is then also autofocus included.
Speaking Autofocus: Manual focus is indeed realized via drive by wire, but is quite well implemented, mechanically even in the fairly heavy Anamorphic sturdy and free of play enough and therefore absolutely practicable. That would be the only restriction because settings such as a Follow Focus are only conditionally reproducible.
Conclusion: Anyone toying with the anamorphic lens, should be equal to order the Pancake as an accessory. The two are then quickly became inseparable pair.
