Mort de rire... (Laughing out loud)
VadymA: I think by the time they get to production Petzval effect will be in every PP plug-in like Topaz, Nik, etc... And after looking at some examples on the web, I don't think I like that effect at all; I find it rather distracting to be honest.
I do not understand very well either what this project brings... This obsolete "system" already many decades ago gives a not beautiful and unpleasant effect. Samyang proposes one 85mm / 1.4 MF of very good quality for cheap or still Sigma with one 85mm / 1.4 extraordinary and Bokeh ultra buttered and especially "healthy" and clean...The quality of the objectives today is such as we do not know any more what "to stand out"... In brief..
To give notes or percentages to cameras réflex or compact of luxury, hybrids etc. is ridiculous!!!... How to claim to be able to say that the Canon xxx will be better than Nikon zzz or that Fuji 111 will be him although the Sony 000?... Today, these monsters of technology with their more and more sharp and quality sensor are quality bombs of image... Later it is a problem of love for a mark, feeling and price especially... Because the RX1 Sony exceeds a little the understanding with these 3100 euros!
Photonix: From the information available it appears that the "Sport" version of the 120-300mm uses exactly the same glass, coatings, and optical formula as the lens it replaces. As best I can tell, here are the differences:
New external cosmetic treatment (S badge, smoother body lines, different finish treatment)New foot design.Compatibility with USB Dock (tweak focus, set focus limit, focus speed, OS mode)New external switch than can be configured with software.
I am not sure I would pay $600 for these new features when the prior version can be had for $3K and deliver identical image quality (which I can say first hand is extremely good). I am pleased to see Sigma starting to produce some really fine glass and give the big boys something to think about. Can't wait to see how this lens with a 1.4x teleconverter compares to Canon's new $11,000 200-400mm f/4.
The global construction has to see nothing more with former Sigma... It is very clear that for the same optical quality, he is frustrating to have to pay out 600 dollars more, but nothing than in hands and in the use, the Global Sigma concept is worth the game!!! We are not far from Canon LAnd nevertheless it remains one 300mm / 2.8 of great quality for less than 3600 dollars!!!
dansclic: High quality at moderate prices ???? I Am dead !!!! If you want quality you have to pay for, cheap stuff from sigma is not a good deal : 50 per cent is decentered, mecanical problems, un reliable autofocus.....So again a 1700 USD Lens and what ? Buy a used nikon or canon instead.
Your comment is ridiculous... Sigma disturbs ultras-Canonistes and persuaded Nikonistes that they have the best material of the world... Sigma proved and proves for a long time that they are capable of making objectives of very high optical quality, furthermore, the last generations at the level of the HSM and of the OS does not much have to envy in Canon and Nikon. know the number of produced objectives not Sigma every year... What stands out in 100 % of products with no problem at all? Nobody!... Do not make of a 4 or 5 % of the totality of products for a majority !
Ridiculous!... What interest to put lenses Canon on a NEX?... Nex is made to have a " compact ", small and light equipement, the one who wants the excellent objectives Canon will prefer to put them directly on a case Canon with a sensor who is called a sensor... Really ridiculous!
Everything those who have 180mm / 3.5 macro Sigma EX HSM can assert that it is great one pebbles... Today Sigma can take out a version 2.8 with stabilization, with their lenses FLD, it is the macro telephoto lens which promises a very high optical quality...For the frame Pentax, generally, Sony and Pentax is always produced late after frames Sigma, Nikon and Canon, thus I imagine nothing before the end of 2012... Or maybe never also ^^
Zebooka: Foveon is not cool. Canon and Nikon wont do this.Foveon looses in terms of color accuracy, the color itself on high iso, noise at high iso, speed of reading data, and bits per pixel. It only wins at slight resolution increase - which is not sufficient as resolution is already high and we are looking at whole picture, not pixel-peep.
??? Did you try the SD1?... If I completely agree that the rise iso is not top above 1600 compared with the technology Nikon and Canon, the colorimetry of the SD1 is fantastic!!! And has nothing to do with the SD14 for example, furthermore, the global quality of the details of all the image is more and more impressive and crushes any sensor APS-C or APS-H, furthermore it remains more detailed that a sensor 24x36 even if he has no curvature and the bokeh of one 24x36... A fantastic sensor for precise images, objects, architecture, etc.... Do not speak about what you do not know!
treepop: Why not have auto focus?
that normal Canon and Nikon protects their science:-)... And in the daytime or Samyang will integrate the AF, as far as this AF is of quality as we can have him at Sigma for example, the prices shall increase anyway by 100 % at least...But well in all the franchising, to have had 85/1.4 and 35/1.4, I agree that for the small price they are on good terms with a very good finish, but the optical qualities compared in Sigma 85/1.4 or with the Canon 35/1.4 are very far backs...
To have had 85mm / 1.4 and 35mm / 1.4, Samyang is a manufacturer just interesting at the level of the prices, to see also on the finish which is excellent but beyond that at the level performances, nothing that 85mm, the Sigma crushes him literally this even if it is 4x more expensively: the dive is 3x superior, AF HSM and not of MF... Furthermore if really we want to taste the bright quality without hurting too much its money, 85mm there is 85mm / 1.8 so much to Canon that at Nikon who are cheap and who are excellent.... At the level of 24mm, gives her is different because Nikon and Canon are extremely expensive, but it also depends on what we look, what is safe it is that Samyang will be far from the quality of the Canon and Nikon and it's worth buying one 24mm / 1.4 if it is to have to close in 2.8 minimum to have a correct neatness while all the manufacturers propose 24mm / 2.8 by dear without forgetting 24mm / 1.8 of Sigma which is rather very good... Samyang = Boofff
Robert Montagne de Cerises: That's a ridiculous price. I bought a Canon EF 100mm f/2.8L MACRO IS USM for less than 800 euros about 2 months ago. One of the sharpest lenses in my collection. What's better about this lens?
Indeed make the difference between the prices of the street and the official list prices... But it is true that the Sigma remains all the same 10 in too expensive 20 % face to face Canon and Nikon 105mm / 2.8 macro... As much the Canon as the Nikon are excellent, let us wait to see the Sigma really and to judge it!
Sigma automatically cheaper because less well, it is finished it... Today Sigma makes well and truly in another category ! 50mm / 1.4, 85mm / 1.4, 120-300/2.8 OS HSM or still 17-50/2.8, 10mm / 2.8, etc. are exceptional objectives...But for the 105mm OS HSM, he is too dear, Nikon and the Canon whether it is technically or optiquement are magnificent, it is going to be difficult for it 105/2.8 OS HSM SIGMA if the prices do not lower little...Sigma cannot be any more compared with Tamron!
YukonRick: I have seen this lens listed at an online retailer for almost $1,000 less than the price above. Just under $500.00
Ridiculous... The new 105mm / 2.8 macro EX DG OS HSM macro will be available that from August, 2011... It is the former model without stabilizer and without HSM who is 500 dollars
