EOS Bodies - For Stills / Re: Backup body for extreme environment
« on: January 31, 2015, 12:27:18 PM »
For environments with extreme climate you need 7D Mark II, or another 7D original. Stay away from the original 5D, which does not have the same level of weather resistance. The 5D Mark iii would be nice, but it seems expensive to consider a backup body.

The year 2017 is already near to be a turnaround in the market. However, if canon wish, you can take the second place in mirrorless. Just launch M3 Dual Pixel AF and viewfinder, and a Rebel SL2 mirrorles.

Frankly I believe that full mirrorles frame has a very small demand. Note that Leica does not even appear in the chart, even if they already manufacture mirrorles full frame before everyone else.

When I say "sales success", I mean sell many units, compared to its competitors. But what are the competitors of EXMOR 36 megapixel? None so far.

When Canon finally offers its 50 megapixel camera, let's find out if EXMOR remains the king in this niche market. I understand that some people really need 50 megapixel, but I think it is not most photographers.

I wonder: ???
If many here want 36 megapixel, why D800, D810, A7r are not big sales successes? ::) :-X

Can't wait to see sample images and sensitivity comparisons...
That's really interesting. A claimed advantage of medium format digital cameras have been that they have color-optimized CFAs rather than high ISO, it would be awesome if this sensor has taken the same type of optimization.
I think a 50 megapixel camera for sure should be optimized at high resolution use cases, rather than trying to be a hand-held low light action camera.
  Actually NO! The trend with MF is to optimize the ISO availability ;-)
A plea to the more knowledgeable people here:
Could you please enlighten me why Canon is going for colour that actually eye perception is UNABLE to differentiate? Or I misunderstood it?
I think you did not understand. A strong color filter allows saturated colors (as a bright red flower) be captured without loss of color depth. In this regard, the old 1DS Mark iii was well above the 5D Mark II, which supposedly would have the same sensor.

It turns out that 1DS Mark iii had images with depth of color much better at ISO100, and noise worse at ISO 3200. I believe that we will see something similar with the new 5DS.

If these specifications are confirmed, seems a natural replacement for the old (and wonderful) 1DS Mark iii, and not for the 5D Mark iii.

EOS-M / Re: EOS M3 24 MP Sensor?

Rumors of new T6i say, 24 megapixel sensor Hybrid AF iii.

If this is correct, it will be an improvement of Hybrid AF ii sensor, found in the Rebel SL1, and is different from the Dual Pixel AF technology.

Possibly the new M3 will have the same T6i sensor.

Has anyone stopped to consider how disgusting humans look in 1080p close-ups and that 4K, 8K etc. are truly terrifying developments?...
I find it amazing how you can take a picture, and then pixel peep to see details you would never notice in the real world....
Can't even make out the colour of your eyes, Sir... Moar DR! Moar Pixels! Canon needs 1080K already!

Fun shot n' crop though, Don... But are these 4K enthusiasts hoping to zoom in to watch Spielberg in motion, directing Indiana from within the reflection in his eyes?

Over here the BBC in 576p is awesome - I fear the Americans and Japanese have simply spent too long suffering with 480i and now they're desperate to overcompensate ;)
Some people (few) really need 4K. ::) But a huge number of people want to 4K to not feel inferior to have lower resolution.  :-\

Small dick complex. :-[ :P

Lenses / Re: Would it be possible to make an EF-S 15mm f/2.8 Pancake?
« on: January 28, 2015, 08:09:11 PM »
I also have a dream with this hypothetical lens, but this is only technically possible with EF-M lens mount, where the distance between the bayonet and the sensor is smaller.

In an EF-S mounting a 15mm F2.8 lens would have to be larger than a pancake, because of requiring a higher number of optical elements, and it would be more expensive than the pancakes 24mm and 40mm.

However, I would like a hypothetical 15mm F2.8 with the same size of the nifty fifty, and costing $300

Sorry for the typographical error, Google Translate could not translate. ::) :P

"To disassemble the camera in the authorized service".

Hi ajfotofilmagem. 
I didn't get a chance to carefully study the correct area as directed by Neuro, I am going to have a look later as the brain fart has passed! Is there a way to verify mould, just it doesn't shift when cleaned, look back after a while to see how big it's got? ???
If the dirt you see in the pictures is not a human hair, can be fungus that grows below the low pass filter.
You needs to point a lantern to the sensor, at different angles and observe the reflection to see if dirt is on the low pass filter surface or underneath it.

If the dirt is under the filter, should be fungus and need desmostar the camera to be cleaned at the authorized workshop.

Lenses / Re: Canon prime rumors? 50mm f1.4, 85mm f1.8 and 100mm f2
« on: January 28, 2015, 08:45:47 AM »
There was no mention of concrete dates, but we all know that updates should appear someday. I've had 50mm F1.4 and I know that this model is the most outdated of the three, so I bought the Sigma Art.

The Canon 85mm F1.8 and the 100 F2 are good optically, and the AF is great, but Image Stabilizer will make them even better. The question is: How much will it be more expensive?

I have the 100mm F2 and love it. I do not know if I would pay $1000 per a version Image Stabilizer.

Is there some reason that this new high MP camera couldn't be the next of the 1D's?  Or is there some details I'm not aware of?
It could be a direct replacement for the Canon 1DS Mark iii, but not a substitute 1DX. In this case there would be a new 1DX (Mark ii?), With up to 20 megapixel and 14 frames per second in addition to the 50 megapixel model with a maximum of 6 shots per second.

Is the new "50 MP" camera going to be in the price range of the D810 and 5D3 ($3-4K) or more in the $6K plus range? 
No one can say for sure. But the market demand is higher in a kind of body 5D, to compete with Nikon D810, possibly costing up to $ 4000.
