 caught the white Chrysler minivan from where they probably shot the Tiger 

Thank you jrista for this detailled explanation! Will we ever come as close to such a great high ISO IQ as Sony demonstrates it, at the same or a similar price tag by Canon? I kinda doubt that, I guess they will ask another premium for that same thing... Sometimes I am pondering about purchasing a Sony A7s for the lowlight pics and keep with the 5D3 for the rest...

I don't know what to expect from Canon. A lot of people seem to be intrigued by small improvements here and there. The 7D II brings some big improvements to the AF system, which is wonderful...and I hope the iTR technology filters down to the rest of Canon's pro line (including the 6D). Beyond AF systems, though...Canon really likes to trickle out improvements, as slowly as possible, and at as high a cost as possible.

I certainly hope that come 2015, they will be releasing something fundamentally impressive with a layered sensor and low read noise, for a reasonable cost. What I expect is that Canon will release something that impresses a lot of people with a layered sensor, and high read noise. So long as Canon keeps using their off-die ADC units, I don't think we will see any improvement on the read noise front, and I think if Canon does that, it will diminish the benefits of having a layered sensor (i.e. they will have much of the same problems that Foveon has...which again boils down to high noise in the red channel and high read noise.)

I hope you are not holding your breath on that.

I would venture to guess, you might have taken a look at metabones and an A7 to complement your Canon lenses ....truth be told;  I have as well, but there are painful compromises to be made.

Canon uses a Sony sensor in the GX7 but insists on using old tech in the Full frame sensors for now... If the last 2-3 higher end Canon body releases are any indicators, there will be definite improvements in high ISO performance, but DR is not something the Canon Geriatric board is considering as a priority (at least in their public statements).

I quote from the DPReview interview of Mr Maeda after the release of the 7Dii: Where he skirts the issue of DR in Canon sensors whether because he considers it un-important, or some other reason... I get the impression, DR is not something Canon top brass is looking to improve upon as a priority, they feel there are other components to a good image it seems...

'DPR: One thing we know from our own testing is that Canon DSLR sensors can’t quite compete with some modern sensors from Sony in terms of dynamic range. How important to you is developing sensor technology?

Mr Maeda: We are very focused on getting the best image quality. I’m not sure what measurements you’re looking at but when it comes to dynamic range for example we consider image quality as a whole, from low to high ISO sensitivities and on balance we consider our sensors to be the best.

My ideal camera is one that can take a picture in any environment from complete darkness to the brightest sunshine.'

Seems he is still concerned about hi-ISO performance ala 5dii, 1Dx, 5diii, 6d etc than other parameters like Base ISO noise, or DR in general. With those professed priorities (like overall IQ in general):  I am not holding my breath on them delivering anything ground breaking in the DR area...  While I enjoy using my 5diii, I would not mind getting a 5d IV or 1dxs when it ships, if it competes well with Sony sensors... I love my Canon lenses. I would love them even more if Canon stuck the 810 sensor in a 5D type body.

Does this count? I did a photoshoot of my little one's Lego indulgence.

Do you have a comparo of the Sport with the 300 f2.8ii + 1.4x iii ?

Sublime is the word that comes to mind when I see all your images.... thanks for giving me a moment of peace and tranquility!

Zeiss Distagon 35mm f1.4, 1DX
1/30s, f1.4, ISO320
Now, that is creamy and smooth!  That doesn't look like a standard turntable and pickup; are you an audiophile, or you found this gear elsewhere?
It's my second addiction. It is a SOTA Millennia turntable, with a Triplanar VII arm and a Lyra Helicon pickup. Pass labs Xono, X1 and X600 amplifiers, Wadia 861 SE CD player and Martin Logan electrostatic speakers, all connected with Synergistic research cables. The sound is quite acceptable :)

Would love to be your best friend :-) haha, glad to see I am not the only one with similar passions.

Not sure if this "Marsh" qualifies as Forest....

I believe I used the 70-200 F2.8 mk.ii.
1/50 sec
ISO 200


I hope it can take 1.4x & 2x mk. iii TC's  without rear element crashing into the TC mount during autofocus like the 70-300L.

Dpreview does some of that comparison, they have it for multiple ISO's and both RAW and jpeg comparison. The latter is what made me realize that Canon's high ISO advantage in the 5d3 vs 5d2 was merely Digic Magic, since the RAWs of both models were quite close.

The issue is, DPreview takes its sweet time to post 'full' reviews, so you one needs to be patient.

I'd prefer more sensitive center AF points... would a -5EV point be possible?

70-200ii,   85 1.2ii

Hi Jon: Thanks for tackling this polarizing topic. Canon makes a great system, and it will be obviously greater still of they used exmors in some regards...

But sensors apart.... as a novice not being able to be as articulate as you guys, I have always felt, that where Canon got beat on DR, was not the sensor, rather the footprint and subsequent processing of the raw file. Whatever algorithms Canon uses to build the RAW file and construct shadow (i.e. half missing) data; needs a re-haul.

This is quite obvious in banding... this is a digital artifact, not an analog output issue form the sensor...

What say you?

Thanks for the correction. Still pretty good for a non-dedicated Camera.

Nice to see cross pollination of technologies by different manufacturers:

The iphone 6+ has:

BSI sensor
Optical Stabilization
Phase detect AF on sensor
1080p 120 and 240fps !

Helps the consumer with choices, and pressures all manufacturers to up their game (just as Samsung is lighting a fire behind Apple :-) )

EOS Bodies - For Stills / Re: Features seen in the past and absent today
« on: September 07, 2014, 02:46:40 AM »
I wonder why canon packed older cameras with some very useful features that are totally absent in modern cameras. Here I refer to the Canon EOS 1D released in 2001 vs modern professional canon cameras.

I refer strictly to:

1/16,000 shutter speed
X-sync speed 1/500

I would think its to do with it being APS, smaller, lighter shutter, less distance to travel etc. Not on modern pro APS now due to cost / usage considerations I would think.
The 1D was an APS-H body with an electronic shutter.

Quick bit of research; also used CCD rather than CMOS which allowed the use of an electronic shutter. So as CMOS replaced CDD those features were lost.

What advantages do CMOS have over CCD (I know cost). but why would a fractional cost be an issue for a $5000+ body?
