On Blackmagic Designs announces Blackmagic Cinema Camera article (354 comments in total)

Seems more a black magic than a camcorder but if that voodoo function it will be a breakthrough in price range. I'm not sure my Vegas 11 will open its raw files although not proprietary.

On Canon acknowledges 'light leak' in the EOS 5D Mark III article (257 comments in total)
In reply to:

Ruy Penalva: Not a very important issue but must be fixed. It is natural that any recent released product shows some minor errors mainly in software but this one if really it is a light leakage is a building defect. A cap in the strap is provided to cover viewfinder in case of live view under direct sunlight entering viewfinder. So we already know that light could alter exposure meter in live view when direct ligt source enter the unprotected viefinder in live view mode. I wonder why MKIII is more priced than Nikon D800 although it has less pixels than it. Is it not that intriguing?

What I'm saying is: Canon is so confident in its product that priced it at a higher level than the one of its strong competitor: Nikon. Is Canon besides a respected brand a griffe to its customers? I'm a Canon customer.

Ruy Penalva: Will NiKon be able to follow Canon paces or will it stay lagging behind?

Why not you wise man? If you love Nikon stay with it but be not unelegant. I'm expressing my opinion not a theorem about Canon/Nikon capabilities. To tell you the truth, I never owned a digital Nikon but I not hate it, simply I prefer Canon.

I think just now Canon is focused on video capabilities of its still cameras, some old interviews with Canon CEOs pointed in that direction. I don't believe that pixels (beyond 20MP) are very important to the vast majority of camera owners who will never print their photos, never. The fact is that Kodak was the first to create a sensor abover 30MP in a 35mmm full frame camera but did not make any success. I think too that what impeded Canon to increase the pixels number of its current sensors was the clear option to video capability. To my knowledge no one market camcorder has a so big sensor in that megapixels range. I think Canon is right and will win the fight by making a more versatile camera.

Will this signalize that Canon will launch a more affordable camcorder too? There is a huge difference in what Canon and their consumers consider affordable.

Canon gave up to improve its still camera to make progresse in video still cameras. But, at that prices, only few consumers can buy.

Peiasdf: It is so amazing but only in well lit situation. Also not much better than SONY's 16/24 mp. 800E is still the high-res king until Canon's 39/42mp 1DsX came out.

But Nokia smartphone already did a camera at this resolution showing that it means nothing. Not forgetting that the troubled Kodak was the first to launch a sensor in that range.

From the conclusion we can say: Sigma has an excelent sensor but a poor software in the days where software counts even more than sensor.

genxseven: $1299 seems expensive. Even with image stabilization, I'd rather buy a Canon 24-70 for basically the same price.

So, I ask you, why Canon, mastering this technology long time before Tamron (who is Tamron compared to Canon?) and other brands, Nikon inclusive, do not put it in this lens recently relaunched and put it in several cheaper non Pro lens? What matter in this focal length with such an aperture is not stabilization. A lens in this price range is made to experienced Pro photographer not to parkinsonian amateur. Even DP was surprised by Canon recent non Pro 2.8 lens launch with IS. Canon EF 24mm f2.8 IS USM. DP questioned if a such aperture lens needed stabilization. I think Canon was clear in its target: Non Pro amateur photographer. But, if this were not a burden it is welcome since we can switch it off and on. But remember, the IS circuit is coupled to AF circuit so a malfuncion in it can compromise the AF.

Do not forget the thumb role of velocity equal the double of the focal lenght, and ISO resources etc to compensate for. If one buys a 2.8 lens is to use that aperture most of time. Besides, a new electronic circuit in a lens circuitry could add an additional source of defect in it. Rarely one buy a lens like that to make very sharp photos. But, if this lens proves to have an optical as good as Canon new 24-70 than the VC may become a minor advantage not to say the price.

It seems that above 12 megapixels all great cameras brands are levelled. Now what decides are: video quality, lens quality, fastness, and the photographer. All other resources like high ISO, low noise etc, are software derived, not a true optical phenomenon. There is not a metareality to be shown by any camera. In fact, all cameras already show many things our eyes is not witnessing.

Almost the weight of the Canon new 24-70 2.8 L (805g) although it carry the burden of a VC mechanism otherwise unnecessary. Canon has 18 elements in 13 groups. MTF charts of the two lenses, cromatic aberrations, light falloff, as well as resistance to humidity is needed to compare the cost/benefit to buy one.

That do not means that autofocus is worthless. Who do not use it switch it off.
