PRESS RELEASE

NEW: THE SLR Magic HyperPrime 23mm F1.7
SLR Magic expands its E-mount lineup with a new wide angle lens
Hong Kong, China (December 8, 2011) - SLR Magic expands the E-mount lens lineup with the new SLR Magic HyperPrime 23mm F1.7 wide angle lens. With this latest addition, the portfolio of lenses for the E-mount system is now comprised of three focal lengths. The world's fastest interchangeable camera lens with APS-C coverage in this focal length, the SLR Magic HyperPrime 23mm F1.7 will be available in January 2012.

The field of view of this new HyperPrime Lens corresponds to a 35mm lens in 35mm format and this fast wide angle of view opens up many new creative composition opportunities, particularly in the fields of candid, street, and landscape cinematography and photography. A minimum focus distance of 0.15m allows for pleasing defocused backgrounds. Additionally, a fast max aperture of F1.7 makes the SLR Magic HyperPrime 23mm F1.7 ideal for available-light photography.

"The world's fastest interchangeable camera lens with APS-C coverage in this focal length, the SLR Magic HyperPrime 23mm F1.7 will be available in January 2012."

The Canon Ef 24mm f1.4 L USM II, Nikon AF-S 24mm f1.4 G and Sigma 24mm f1.8 EX DG Macro also cover APS-C ;) .

I guess with 24mm focal length what they said is still true, 24mm is not 23mm ;) .

Well, we will test this ASAP anyway.
24mm is never really 24mm - this is basically just a class. If they provide their true focal length I've no issues here.

They will have a more thrilling announcement in a couple of weeks ... SLR Magic is an interesting new player (despite their name).

The Zeiss 24/1.8 for NEX is almost as fast.

And how much more expensive ?
Are you willing to pay a grand for a moderate wide-angle lens on APS-C ("37mm f/2.5") ?

Zeiss has full AF and electronic contact. Does this SLR Magic lens have at least electronic contact?

No, it does not. At less than half the price and slightly more attractive optical specs.

People are willing to pay more for AF and reputable brand

I guess SLR Magic (yeah, sounds a bit goofy but anyone who finds the name objectionable can just tape up the lens. I don't mind the name) has begun producing their own designs instead of rebranding CCTV lenses. I hope they (and Samyang) can put a bit of pressure on the OEMs. Of course the lack of electronic coupling and AF is a deal breaker for me. For low light work I'd scrape, save and buy the Zeiss (which is only a hair slower at f/1.8). YMMV.

Samyang and SLR Magic are both small companies. I think that it is not that easy to produce a reliable AF combined with decent centering quality based on small production volumes. The AF lens group must be comparatively smaller and more "loose" than a MF lens group because it must not produce a high amount of friction.
I agree that an automatic aperture should be doable though. However, even Voigtlander is shy of this (see the 25mm f/0.95).

SLR Magic is using "Tantalum" elements - this seems to be promising based on what we've seen (we are in contact with them).

The AF lens group must be comparatively smaller and more "loose" than a MF lens group because it must not produce a high amount of friction.

I just hope they will get over this sometime. I mean, if Tokina (the smallest third party manufacturer of the first tier) can do aperture control and AF - at least in micro motor flavour which is not stellar but acceptable - why can't Samyang. With E mount it should be even easier as Sony has released the specs (though I'm not sure now whether they released them into the public domain or just to select companies like Cosina - which makes the Voigtländers BTW - Sigma, Zeiss and Tamron).

I guess teamwork and cross-licensing is the key. Why can't they team up with some other manufacturer out there to swap the AF know-how for some optical designs. I almost wish Samyang teams up with Sigma to bring AF to the korean 35/1.4 and 24/1.4, especially the latter since I'm in a need for such a lens but won't be able to afford the Canon L equivalent for, like, several years.

I agree that an automatic aperture should be doable though. However, even Voigtlander is shy of this (see the 25mm f/0.95).

I thought the Voigtländer lenses in Canon mount have the chip for aperture control, EXIF and whatnot? (not sure since you reviewed Nikon versions using an adapter). They probably just failed to crack the MFT protocols so far. :D

SLR Magic is using "Tantalum" elements - this seems to be promising based on what we've seen (we are in contact with them).

Looks like the glass with exotic additives is the future, with previously unheard of performance/size ratio and wonderful quality feats. :) I hope they won't be using Thorium tho. :D

It's a bit strange that Voigtlander has this fully manual 25mm f/0.95. They are an official member of the FT consortium so they actually have full access to the specs.

That fact eluded me. Weird indeed. The only answer I have is that they ran into unresoluble some issues when designing or producing the lens and so decided to make it "as is", fully "dumb".

Oha, this lens sounds very interesting. In fact, I might even get a new 5n because of it, once the clicking video has been fixed. With this lens my greatest handling issues are practically overcome. I found it a nightmare to use the awkwardly placed back dial of the 5n to change the aperture (somthing I do before practically every shot). Since this lens is all manual i can conveniently change the aperture on the lens itself, which should work much better. I just hope the optical quality holds up. If so, this is probably a game changer for the nex system.
