Canon have provided pretty impressive MTF graphs with both TC's, so I'm putting money on it working with them.

I don't understand what you're expecting to see? Resolution and sharpness are hidden at 1920 pixels wide, DR isn't an issue with lighting like that, and high ISO looks pretty impressive. Other than handling (which the pictures can't reveal), the way the scene is rendered is down to the lens.I have a 550D and i see no difference at all.
What difference are you expecting, exactly?Quote from: pleasehelpTo be honest i wonder first and foremost that i see no difference at all after so many Sensor generations.
I mean is this already the end of what we can expect?
Is there only an ISO improvement from now on?
Well, assuming the 7DII sensor is basically similar to that in the 70D (minor tweaks), you're talking about one generation. One.
Sorry im not up to date.
But that "generations" was of course in reference to my 550D.
Since my 550D, i bought 2010, nothing has happend?
Image quality in my compact cameras has made big steps forward.
When i compare images from my old P&S cameras to todays i immediately see a difference.
When i look at the 7D MK2 pics they look exactly like my 550D images.
And I just looked at the links quickly on my phone. Well spotted.Because actually, the link for the C lens in Maximilian's post is wrong.Yes, sorry! Link was wrong, c&p error.
STM lenses make a high pitch noise, almost similar to a loud version of baldy shielded processor noise leaking into amplifier circuitry. Nothing like the volume of micro motors of older cheap lenses. It's almost completely silent, and great for video work. USM motors are silent to all intents and purposes, although there is typically the noise of components other than the motor - the internals of the lens gliding over each other etc. And of course there's the fairly abrupt torque as the AF system start/stops to achieve its fast focus acquisition speed. This is no good when it comes to slow, smooth video AF requirements as the USM system will go through a constant start/stop sequence.
A little surprised the 85/1.8 is quieter than the 40mm.... isn't the STM supposed to be a quiet motor?
1. 7d and 500mm f/4 is 800mm equivalent and f/5.6 equivalent like DOF capabilities and rendering the fore/backgorund.
2. 5d iii and 500+1.4 is 700mm f/5.6 mm lens
You do not want 800 for crop. Your subject will be to far away and the air between the lens and the subject will blow your IQ. Believe me. Even 600 is to long for crop sensor.
+1Has anyone noticed that the 'true' max apertures as indicate by the Tstop is nowhere near the manufacturers claim? The Zeis is closer to a f1.8 lens than f1.4 and the rest fare no better....
T value is not aperture value, an f1.4 lens is a "true" f1.4 if the apparent aperture diameter is focal length divided by 1.4. The T value relates to actual light transmission and is pretty much irrelevant with TTL metering stills cameras.
Aperture value is always lower than T (transmission) value because however good the glass is you always lose some.
12mm for full fisheye coverage? Insane... 15mm is hella-wide as is with fisheye.A typical fisheye at 15mm provides 180˚ coverage, corner to corner. Typically you can't get any wider than that without mechanical vignetting in the corners (as is the case with the 8-15 when zoomed below 14mm), or with a lens wider than 180˚ (some go up to about 185˚).
And what about IS while shooting in 200 mm range handheld with shutter speeds 1/2000 and faster?In some scenarios, it's a must - as highlighted in my above post. Although in typical handheld scenarios at that length and shutter speed, it's only there to stabilise the viewfinder a touch, making composing and getting the AF points on the subject slightly easier. However, if you really prefer not to use it at such speeds, just turn it off.
Would the focal length of 12mm, vs the 15mm of other diagonal fisheyes, mean it uses a different projection? The linked page says nothing about that.I'm guessing that unlike a normal fisheye such as the Canon offerings (current and previous), this will be like the 8mm APS-C (1.5x crop) Samyang fisheye which has a stereographic projection. 8mm x 1.5 is 12mm, so it's a good fit.
well last rumor heard from a good informed source close to canon told me.... canon will introduce exchangeable sensors.Yeah, DPAF has definite speed advantages over standard phase detect AF for DSLR's, and that big mirror and shutter blocking out the light to the sensor where DPAF is situated at the time of acquiring focus doesn't matter at all
there will be no phase detection AF anymore because it´s obsolete.
DPAF II is now faster and way better.
so maybe the 7D MK2 Standard comes with APS-C and the Edition model comes with a FF sensor.
