SLR Magic 2x ANAMORPHIC lens http://www.personal-view.com/talks/discussion/4466/slr-magic-2x-anamorphic-lens Tue, 04 Sep 2012 15:35:25 -0600 slrmagic 4466@/talks/discussions Dear All,

We have received 4 email requests from members of this forum on the possibility of designing an Anamorphic lens. We had this thought for the past year and did a lot of research. There is one common request which is to have horizontal flares. The others requests did not have any common grounds. We came up with an idea for a 25mm f/3.2 1.35x or 35mm f/3.2 1.35x Anamorphic lens for micro four thirds. Shooting at 16:9 would give a 2.40:1 anamorphic output. Just before we decided to go ahead with the project we had a second thought. 2 Years ago we asked openly on dpreview.com forum for what photographers wanted and the general consensus was our SLR Magic HyperPrime 12mm T1.6 lens.

http://forums.dpreview.com/forums/read.asp?forum=1041&message=36104678

It did not fulfill the needs and wants of everyone but we made what most people agreed on by means of a discussion. It ended up being a popular lens that we still are having problems meeting demand and we think it had a big part to do with asking photographers. If we did not ask around we probably made a 12mm f/2.8 lens. As it turned out quite well last time we want to make our next lens an open discussion again.

Here are some of the possible options we received and please feel free to throw in extra ideas. I hope people experienced with shooting in Anamorphic can also throw in ideas.

Anamorphic Adapter (1.33x, 1.5x, 1.75x, 2x) Dedicated mFT Anamorphic adapter for reasonable size Anamorphic adapter compatible with FF lenses 50mm f/2.8 Anamorphic lens (FF, APS-C, or mFT) Expected MSRP (Sad fact but it as direct correlation to IQ)

Kind rgds., SLR Magic Team

P.S. We will be at Photokina 2012 and would like to welcome any cinematographers with Anamorphic lens ideas to drop by our booth for idea exchange! We will be in Hall 3.1 B059

Hidden gems among lenses http://www.personal-view.com/talks/discussion/80/hidden-gems-among-lenses Thu, 12 May 2011 00:39:39 -0600 Vitaliy_Kiselev 80@/talks/discussions
First one - Vivitar 28-200mm F3.5-5.3

1) Buy only original 28-200mm as in picture below. Tokina is absolutely different lens with different optical formula (look at crop from Vivitar box, Tokina have fewer elements).
2) For Pentax, lens could come either in PK/A or PK A/R mounts. In former you must remoive Ricoh pin. On both you must use file to remove excessive lever protection.
3) Closed down, lens is PP friend. Good wide open, but as on many old lenses have some abberations. Contrast is lower due to many glass surfaces and not top-notch coatings. Abberations are almost absent if close down (see below).
4) Corners are controlled quite well.

The new Zhongyi Mitakon 42.5mm f/1.2 Lens features an incredibly fast aperture of f/1.2, making it ideally suited for low-light conditions shooting, greater control over selective focus and shallow depth of field imagery. Designed for the use with an APS-C-sized camera sensor, the lens gives a 35mm-equivalent focal length of nearly 64mm. Above features provide an excellent portrait shooting solution for mirrorless cameras users. The lens also houses with 7 elements in 9 groups of optical lenses to provide great deal of image clarity and color renderness.

The lubricant in the helicals has turned to non-lubricating goo and the movement is very stiff and sluggish. I want to have it cleaned/overhauled and modified so that it is parfocal on the BMPCC throughout its zoom range.

Three names come to mind to bring this lens production ready: Bernie O'Doherty in New York Edward Koehler in Germany Les Bosher in Wales.

Does anyone have other recommendations for engineers who can do this work?

During the shooting of the Takumar I caught some specular reflections. I recently built an automatic indoor bird bath for my parrot and it's got a little lightshow that goes off every time it turns on. Those lights showed up in the test chart without me noticing - and I'm way too lazy to reshoot. :D

These were all done on the 1m chart at ISO 100, with AE turned on. WB was set to the chart's white looking through the Canon FD 50/1.4 SSC and left there so the color differences (for white at least) could be compared. I only included the right and left corners cuz that's pretty much mid-area if shot on a FF anyway (not center, but mid).

This test obviously won't tell everything about a lens like how sharp it is when focused to infinity or what the bokeh is like, but I guess it's a pretty good comparison for these to show sharpness at one meter. And 1 to 3 meters is nice bust portraiture with a 50mm on the GH1.

The chart numbers are to be multiplied by 100 to get LPP (Lines Per Picture). But actually, since I was pulled out just a tad in order to use the box for framing the shots, maybe multiplying by 107 or so would be more accurate. :D I shot them all in 4x3 format on a Linhof tripod, with the 10s timer, using the 15X zoom MF assist - using the right-most red box (above) as the focus point.

The Canons seem to be the winners (in this test) but all of those are IMO excellent lenses - except the Rokkor-PF F/1.7 maybe. And it's an awesome looking antique. I have a bunch of other 50's that start at 2.0 or greater which are also very wonderful - like the 55/2.8 Nikkor Micro, the Minolta AF 50/2.8 Marco or some of the Zeiss/Jena Biotars and various Tessar implementations, etc..

I also wanted to test the Voigtlander 50/1.5 but I can't seem to find my adapter.]]>

I have the SLR Magic 12mm lens with me which is a 24mm equiv on the GH2 and will be 28mm on the GH4 in 4K mode. The samyang with the SB will be wider (14mm on the GH2 with SB & 16mm on the GH4 in 4K mode and will be a F2).

Which out of the 2 is the better lens? I have the option of selling the SLR Magic to a film maker i know and the Samyang costs roundabout the same as what i am selling the 12mm for.

Kindly advice.

P.S- I have been recommended to go for the Samyang compared to a Tokina 11-16mm (EF) as they said It's sharper and has better CA control. Views on this.
