EOS Bodies / Re: A 2014 Roadmap Part 1: The 7D Mark II is Coming [CR2]

exposure time should remain completely under (stills) phtotographer's discrete control.
It is much more tahn only a technical parameter to achieve "correct" exposure of a scene and/or images free from shake-induced blur and from motion-induced blur when moving subjects are in the scene.
While for many images photographers will be happy with an exposurte time in a fairly wide range, there are many other situations, where we want to set a specific exposure time to achieve certain effects in the image .. from completely frozen motion t0 "dragging shutter" to consciously make motion blur show up. This would be defeated if the actual exposure was a composite of a series of "nano-sliced" exposure times selected at the camera algorithms' discretion. To me only acceptable in operating modes where exposure time is already currently set by program parameters/algorithms ... "green box", Av, P - but definitely not in Time Value ("Tv") or Manual ("M") mode.

A day with decent lighting and I'm often at ISO 1250 with the 6D and no complaints so that may not be too big of an issue.  If a 7D2 would handle that with ease I'd be happy.  I think the two would complement each other nicely.

Unless you relly want/need a second body and are willing to lug it along you might be better off with a 5D III [not to mention a Nikon D800]. Gives you a better AF-system than 7D and virtually equal IQ to 6D.

Well, I'd say in real life a cropped EOS 6D pic won't quite cut it [below ISO 1600 that is], but a cropped D800 FF pic (15.3 MP) is better than a 7D  APS-C 18 MP picture. I've seen it. :-)

EOS Bodies / Re: Canon EOS-A1 with Hybrid EVF? [CR1]

Sony TruFinder EVF used in A99, NEX-7 and A7/R to my knowlegde is 0.5" OLED  @ 1024x768 (XGA) RGB.
If I made no mistake using Pythagoras, that calculates as 2560 ppi  [if c=0.5" and a:b = 4:3 then -> a=0.4", b= 0.3" -> 1024/0.4=2560 or 768/0.3=2560] 
Viewed from a distance of about 1 inch (if at all).
Should be plenty resolution for any human eye, no matter what eyesight, or not?

all those woul would "love to get a hybrid viewfinder" .. .could you elaborate in a little more detail, how exactly you would like to have that implemented?

* optical rangefinder with EVF overlay (Fuji X-Pro1 style) with or without optical parallax correction .. if yes, to what focal lengths and focus distances?

* fixed, semitransparent pellicle mirror (Sony SLT, Canon EOS RT) style?

or ... what else?

Willing to accept and swallow all the "unwanted effects"?
Let's face it, time is ripe for EVF. All that's needed is just one more little push ... a higher res [why not 4k?]  OLED display with no discernible lag [lets say less than 3ms - or any other number you consider good enough] and no blackouts between shot. POf course combined with 100% mechanics free, vibration-free global shutter (electronic).

Anybody unwilling to accept EVFs will be relegated to using OVFs as long as those will be available in old-style "niche" DSLRs.  Similar to analogue film cameras.

Again, I urge you not to think of this as an engineering problem, that's the wrong approach; pricing is a business problem, not an engineering problem.

Even if all the video crap in DSLSr would really be "for free" (which it is not) I still would like to have a choice. And no, I am not interested in agrossly overpriced, useless UI retro Nikon DSLR (Df) but much more so in a a 5D IVs ... "video-free" in a Sony A7 sized body. :-)

@mkabi: all you and your video buddies need are better videocams/camcorders. So please go and ask manufacturers for better videocams. If you think Canon's C-### videocams are grossly overpriced or lacking in performance and features then ask Canon to make better ones and cheaper ones Or get yourself  a full-frame sensored Sony Camcorder with interchangeable lens mount for less than 3k. Unlike any DSLR it is perfectly suited to capture videos.

But please do not try to force ever more video-optimized crap upon stills photgraphers who may occasionally like to WATCH a film or video but have no desire whatsoever to MAKE videos/films with their cameras.

I have been unwantingly using "video-enabled" cameras for more than 10 years now. I had to pay for those video features that was forced upon me with no option to leave it out. And in all those years I have never ever captured anything other than a 15 second test clips with them, just to see if a new camera is fully functional.

I am also NOT interested in a video-optimized hybrid-EVF camera. What I want is a Sony A7R-killer from Canon: a very compact,  "stills-optimized" mirrorless camera with the best possible-IQ FF sensor (hi res, high DR, low noise up to very high ISO), an excellent AF-system [5D 3 or better], contemporary connectivity features [WiFi, GPS, Radio flash controller] and a highly efficient, easy to use "stills-oriented" user interface. Video? Well, yes - as a LiveView feed.

And instead of Hybrid EVF/OVF I want a truly hi-end EVF only. 4k resolution, no discernible lag, no black-out. :-)

So..what's the word?
This works well with the 600RT's as advertised?
Inquiring minds want to know!!

How was the 50D I downgrade? Just curious. I can see the 60D, but 50D?
50D sensor was hardly a progress over 40D.
But you are right, I meant the downgrade with no AFMA ... that was 60D then right?

Canon only barely retained me as a customer in 2009, because they finally brought the 7D which I considered to be at least as good as the Nikon D300s. And because Nikon had and still has no stabilized 17-55/2.8 lens ... and still does not have one to the day. Without 7D - meaning something as lame as 50D or 60D - I would definitely have switched from my 40D to Nikon back then.

Don't count on that happening, I wouldn't advise buying a 70d expecting an af feature update that brings it up to the 7d1 level - Canon is not in the habit of doing *any* updates on the xxd cameras, they're to be sold and used "as is".

exactly! "Upgrades" for Canon xxD users are available solely by purchasing a "new" (incrementally improved) xxD body. ;-)

And sometimes it turns out to be a downgrade ... 50D anyone?  :o

EOS Bodies / Re: Why do you want a FF Mirrorless?
« on: December 18, 2013, 03:39:30 AM »
Where do you think, will we be a year from now [year end 2014] regarding mirrorless FF?

I'll boldly go first:
  • Sony Alpha A8/R announced; 10 native Sony, SonyZeiss FE lenses available; A7 lowest street price USD 999 and A7R @ 1499
  • Canon - "development announcement" out
  • Nikon - "development announcement" out
  • Sigma - non-Bayer FF mirrorless available
  • Fuji - announcement out
  • Hasselblad - "Solar" and "Solar R" available at USD/€ 10,000 and 15,000 - with wooden grips

join in and we'll re-visit the thread a year from now!  ;D

in camera cropping or digital zoom is great with an evf so you see what you see is what you get. it would be splendid with a high mp ff mirrorless body. when canon makes a big mp ff body like the d800 then it should have a crop mode also, its better than not having it but you just get a crop square in the viewfinder. i don't know if there is a good way to change the magnification of what you see in the finder when you switch to crop mode?

Yes! Perfectly implemented crop mode with EVF is available. Sony A7 = 10MP in 1.5x crop mode, A7R = 15.3MP.
Canon would not even have to innovate. Just imitate. :-)

The two cameras are perfectly capable of using existing E-mount and A-mount lenses, and you have the choice as to whether the image is cropped. If you choose to crop, the resolution will drop to 15 megapixel on the α7R and 10 megapixel on the α7, and the equivalent focal length will increase by 1.5X. Sony also gives you the option not to crop and use the entire sensor, though this may lead to strong vignetting (and for most lenses, probably will).

The camera offers three options for its APS-C crop mode - Off, Auto and On. With it switched Off, you'll see Image 1 with a full-frame lens and Image 2 if you're using an APS-C lens. In the default, Auto, mode you'll get Image 1 or Image 3, depending on whether you're using a full-frame or an APS-C lens. And finally, with it On, you'll see Image 3, regardless of which lens type you put on the camera.

Third Party Manufacturers / Re: Sigma 135mm f/2 DG OS Art Coming? [CR1]

How do you improve on the 135L?

Well, I'd love to get any or all of the following improvements:

  • 100% more IS
  • 10% better IQ
  • 50% less price

It better be, considering they want to charge almost $1200 for it ... I'll be one of the first in line to get the Zeiss 24-70 f/4.

yep. will be interesting to see, how it will compare to the Canon EF 24-70/4 L IS ... MSRP are the same and streetprice will be similar too once the SonyZeiss gets to full availability.

After reading Roger Cicalas blog re. SonyZeiss FE 35/2.8 and its optical qualities I expect the 24-70 to be very good too.

Excellent progress compared to last year I'd say. :-)

In one sentence: First ultra-compact, well-specced, hi-IQ mirrorless FF cameras available ... at surprisingly affordable prices. :-)

In more words:
  • Two mirrorless FF-sensored cameras available
  • Very attractive pricing on A7 and A7R
  • Excellent sensors, one model with (arguably) best sensor (res, DR) on market
  • Ultra-compact and light bodies, solid build
  • Useable fps and AF ... but not at DSLR level; no tracking, not for action
  • Very decent EVF ... but still XGA (not "retina"); still some lag; blackout between shots
  • Very decent feature set, UI, controls, ergonomics, WiFi
  • no in-body IS
  • no built-in flash
  • Poor battery charge
  • Shutter disappointing - mechanical, noisy, no silent mode, no high X-sync speed
  • two compact & light Zeiss primes available at launch - optically excellent, but not cheap
  • Kit-zoom available - not as small and good as hoped for, but reasonably low priced
  • Better Zeiss-Zoom 24-70/4 coming up soon
  • Adapters available, many brands/sorts of lenses usable
  • ...
  • Sony has delivered and seems set to deliver more ... see lens roadmap
  • Canon and Nikon still firm asleep at the wheel.
