On Samyang announces 16mm f/2.0 and 300mm f/6.3 Reflex lenses news story (125 comments in total)
In reply to:

brunobarolo: I don't think they will sell a lot of these lenses in m4/3 mount. The Oly 17mm f1.8 weighs less than a quarter, as compared to this Samyang lens. And it offers AF and doesn't cost that much more.

It may, however, be interesting for some APS-C DSLR owners who haven't been blessed with a fast wide angle from their respective camera makers by now.

Well, it will be a wider angle for APS-C, more comparable to something like a 12mm lens for MFT. That Samyang has thrown in MFT as an option, it is really a lens designed for APS-C.

In reply to:

Juck: A slow, manual focus 300mm mirror lens? That on anyone's shopping list?

Is there such thing as a fast mirror lens? The big advantage is its size/weight. The typical zoom will get you 300mm f/5.6. This mirror lens is only 1/3 stop slower.

As for manual lens... it is something the target market enjoys.

I really admire Samyang, for being relentless and delivering quality without a premium. Although, it likely helps that they are fully manual lenses (very much welcome in my world). That being said, I'm also curious to see if Samyang is indeed ready with AF options for Sony NEX (E-mount) as was supposedly promised last year and scheduled for 2013.

It will be even more impressive, if Samyang delivered a 14mm f/2.8 compactized and designed for Mirrorless.

tornwald: It still seems to have a Bayer matrix and therefore Foveon remains superior for me. Interesting development although, let's see how this works in practice.

Sony's patent (in early 2012) on organic layer points at a Foveon-like stacked structure. I won't be surprised if the same applied to Fuji's.

In reply to:

bcalkins: Sounds promising!

Sony's patent for organic layer does indeed include a three-layer stacked structure and I won't be surprised if Fuji's patent does too.

Organic-Inorganic Hybrid Sensor may indeed be the next thing. Sony too had filed a patent in Spring 2012, with a similar organic layer that supposedly enhances sensitivity and the DR, apparently, also eliminating the need for OLPF.

On Samsung introduces 10mm F3.5 Fisheye for NX news story (101 comments in total)
In reply to:

Michael Barkowski: This is soooo much better than anything Sony has to offer.

@ HowaboutRAW

I would take Sony 35mm/1.8 OSS E over Samsung 30mm f/2 ANY DAY. But then, I shouldn't really argue with someone who believes the 30mm/2 has expectations of Leica performance from it.

The 30mm is a good lens, but it ain't something to go screaming with joy about.

In reply to:

Emacs23: Curiously to know what projection this lens use. I love the stereographic of Samyang 8/2.8 and I doubt this will have it too.

Stereographic projection used in the Samyang/Rokinon Fisheye is a Samyang patent, I believe.

chiumeister: the Sigma 35 1.4 on the Sony A99 full frame will give you image stabilization. Although you cannot use the full 1.4 aperture for video.

In manual mode, you can.

On Canon still pursuing Foveon-style multi-layer sensor design news story (165 comments in total)
In reply to:

BJL: How about calling this technology "X3", which is the jargon adopted as an industry-standard by CIPA? "Foveon" is just one approach to X3, and not the one that Canon is pursuing, and the "X3" tag is also well-known.

Or, "RS", as in EXMOR-RS? :D

Greynerd: I do love it when sigma bring out a new lens for m43. There is such a massive struggle for so many users with the concept that people would want to buy a cheap lens when they can just get a better lens for lots more money.
No macro. I mean really really mega slow at f2.8, no distance scale, no DOF indicator - it just makes you shudder with the horror of it.

Back in film days, rangefinders often came with a 90mm f/2.8 or f/4 lenses. This lens is technically an APS-C solution for the same effect. That it is available for M43 is merely a case of the option being thrown in.

On APS-C (Sony NEX), this lens, in terms of FoV and DoF, would compare to 45mm f/1.8 lens on M43 which isn't too shabby.

And no point really for distance scale or DOF indicator.

In reply to:

domina: no distance scale? no DoF scale? why? who will use a lens without a distance scale? I'd pay more to have a distance scale. Also, an aperture ring (in addition to electronic aperture control) would be very welcome even at higher price. Also, a lens hood is a must.

Neither is of much use (or accurate enough) in real world, and more so since Sony NEX system allows live DOF.

In reply to:

cprevost: They will sell tons of these. Nothing else like it close to this price range. Hoping it goes down just a bit in price when it actually hits the street. If it's as good optically as the other two they'll have a hit. For many of us 60mm on micro four thirds is a focal length that doesn't get a ton of use so paying hefty prices for one doesn't make sense. Hoping it makes a fine portrait lens.

I love the depth of field and subject isolation I can get on my oly 45mm. How would this lens compare? I know it doesn't open as wide but would the focal length make up the difference?

That is a good point Wally.

In reply to:

ZhanMInG12: No macro ability at this focal range? Making it to 0.5x wouldn't really hurt, right?

I'd rather see a 105mm macro than a 60mm. This is simply a completion of the traditional rangefinder trio, like Contax G (which was 28, 45 and 90mm). If a 90mm lens on film made sense back in the day, the 60mm on APS-C is that lens today.

Diopter: 10mm or 12 mm prime for the E is still deep in the woods.
So a macro in a useful focal lenght .... :-(

When we see inexpensive ultra wide primes, it will be time to raise our expectations. Until then, no. The best bet comes from Samyang, but it might not be a sub-$400 lens if you want quality (and they are pretty good).

That begs the question, which 10mm or 12mm lens do you carry for your street photography, at budget prices?

forpetessake: Hm, not sure what is this lens for. On m4/3, it's equivalent to 120mm/5.6, hard to think of a useful application. On APS-C, it's equivalent to 90mm/4.2 --good FL for portraits, but too slow for that; the existing SEL 50mm/1.8 though slightly short is much better in the other respect. Sigma for some reason releasing lenses, which add little to existing native lenses, how are they going to sell them?

I would say, pretty useless on MFT. On APS-C, not so much. 60mm f/2.8 on APS-C will create a good separation and if this Sigma is like the other two DNs (19mm and 30mm), or Sigma 70mm f/2.8 macro that I have, it will not need to be stopped down. Doing so will allow acceptable sharpness to co-exist with just enough DOF. Even if the lens were an f/2, chances are, most will stop it down to f/2.8.

Sony 10-18 f/4 is pretty good for UW lens. And for a prime, Zeiss is covering it with 12 f/2.8. Samyang is expected to announce its own line of AF lenses for E-mount this year (the decision to do so was put forth last year) and they have 10mm f/2.8 UW too. It won't surprise me if they develop an exclusively E-mount version of that lens as well (as they did for the 8mm fisheye).

In reply to:

smithore2: Where is the weight in the physical specifications?? 1kg???
Why 2.8, it's equivalent of 5.6 in dof on m43, that's too much.

M43 equivalent for this lens will be 45mm f/2.

I suspect the Sigma 60mm to be about 200g.
