Lenses / Re: EF-M 55-200 4.5-6.3 IS STM Coming Shortly
« on: June 17, 2014, 03:12:01 AM »
f/5.6 --> f/6.3 is 1/3 of a stop.  REALLY people?  You're going to ***** and moan about 1/3 of a stop?  Seriously?  OBVIOUSLY, the point of the M is to shrink things down as much as possible.  1/3 of a stop throughout the focal range is a "duh" kind of compromise.  As in... DUH... DO IT!  (when talking about mirrorless)

Yes, I do take issue with f/6.3 - beecause in practice it likely means T/7.9
Instead of filter thread 52mm, Canon shouild have made it f/5.6 and 55mm or f/4.0 and 58mm filter thread, even if that wozuld have meant 50 grams more or 100 grams more weight and 50 dollars or 100 dollars higher price.

F/6.3 ... and in reality probably T/7.9 ... no way. Too much of a compromise. They should have made it f/5.6 even if that would have meant only slightly smaller than the EF-S 55-250. i'll continue to use that one ... Plus adapter ... Which is nice anyway because it has a tripod foot for my mini-tripod. :-)

I guess it's DXO (not Sony themselves) saying 15.3 EV ...
You guess wrong.  This is from Sony's website:

ups ... oh my ... didn't see that one. Where I am from Sony would not dare do this, they might get sued for misleading advertising here. :-)

I think things change too.  As metering gets better and better, and more and more accurate, auto ISO, IMO, will become more popular.  The 1Dx's metering in all metering modes is super, super accurate whereas earlier models not so much.  So I think people's preferences may change as technology improves.

I think our favorite spot on the mode dial is a religious matter -- it often defines our first priority to shot and everything else follows.  Mine is locked on Av unless (a) I deliberately want a specific shutter (< 1% of the time) or (b) I've got the flash on in really low light and I go to M.  It's not right, it's not wrong.  It's what I do.  Each of us has our own sensibilities to follow.

But ISO is different to me.  It's the part of the triangle I am most flexible on to get the rest of the settings where I want them.  I bounce all over the place on ISO, even using Auto ISO (gated to 1/(lens FL) shutter) in difficult / rapidly changing lighting or in spur-of-the-moment shooting environments.

- A

also my approach. :-)
Focus plane and Aperture always control look & composition of an image. Shutter speed only if subjects and/or camera are moving. ISO is irrelevant for composition, its only about "technical" image quality and if we keep it within our "tolerance levels", its the least important of the the 4 shooting parameters. That's why better implementation of Auto-ISO in Canon EOS cameras is so crucial [eg. "M + Auto-ISO + working EV compensation" not only on 1-series cameras] ... to have a good tool to handle quickly changing lighting situations that are not under our immediate control.

I have corrected it, I was looking at the 70D line in my spreadsheet of specs.

thanks! And now some more juicy details please. Brilliantly working Eye Control AF v.2.0 would be the one feature that would make me pre-order it. Despite the fact it's stil a mirror-slapper.  ;D

Nevertheless Sony A7s is a useless product. ... And 12 MP resoultion is just not goin' to cut it in terms of resolution for a stills FF camera in 2014.

But...but...Sony says it has 15.3 stops of DR.  15.3 stops!  Never mind that it has only a 14-bit ADC, and if it uses the same RAW format as the a7R it won't even have a 14-bit RAW file.   ::)

I guess it's DXO (not Sony themselves) saying 15.3 EV ... after downsampling the image to 1 MP or so and printing it on some piece of paper using a home-office inkjet printer  ...  ;D

354
At 18MP, the X produces clean photos at 12000ish, low light.

yes. and Sony A7s is 2500 at launch and will be below 2000 street pretty soon. ;-)

Nevertheless Sony A7s is a useless product. 4K recording only with a not-yet existing 3rd party recorder (expensive and 2 peieces of equipment to lug around). And 12 MP resoultion is just not goin' to cut it in terms of resolution for a stills FF camera in 2014.

Still looking forward to an improved A8R ... same sensor, better AF, fully electronic, 100% mechanics-free shutter  with X-Sync to 1/8000s, battery charge 500+ shots and a 4k "retina" EVF ... and no video out whatsoever. ;-)

EOS 7D has 100% viewfinder coverage +/- minimal tolerance and 1.0x mag 

EOS 70D has 98% viewfinder coverage and .95x magnification.  ;)

there are only so few differences between film and digital photography. Your eye, your imagination, the right moment and good composition still reign supreme. Aperture still controls depth of field. Areas in-focus and out-of-focus and their relation to each other. Colors, contrasts, lines, areas. Shutter speed still controls blur vs. sharpness for moving subjects. Visual isolation  vs. inclusion of context.

Things to plan and keep in mind before taking a shot, while taking a shot and processing an image once its captured. 

Differences? Much faster learning curve. Instant and full feedback - visually and with all capture-relevant data. Seeing, whether something worked or not ... immediately ... not only days or weeks later.

Painting with light, converting photons directly into electronic images, rather than having to take the cumbersome, indirect route of transforming light-sensitive chemical substances from one state to another.

Absolutely fantastic. No nostalgia whatsoever. I don't want to be a chemical laboratory worker. I don't want to be an optician. I don't want to be camera-machine operator. All I want, is to capture and create images with technology as simple, effective and unobtrusive as possible. We've com,e a long ways towards that goal. So glad I live in the digital age.  8)

EOS Bodies / Re: 7D Mark-II as an action oriented DSLR
« on: June 14, 2014, 05:02:53 PM »
Note: this is not what a "wish list" but rather a prediction based on the market, competition and Canon's existing lineup:

24 mp dual pixel APS-C sensor;
Sensor performs marginally better than 70D sensor;
Autofocus equal to or exceeding the 5DIII;
Dual card slots, one each SD and CF;
Weather sealing somewhere between 5DIII and 1DX;
Mode dial replaced by 1D-style button (After CR Guy surfaced this rumor, I started thinking about it and it makes sense);
Touch Screen;
Integrated Wi-Fi and/or GPS;
Accessory grip/battery holder with weather-sealing slightly superior to 5DIII grip;
Frame rate slightly better than current 7D (Maybe 1-1.5 fps faster);
Pop-up flash with optical trigger (same as 7D);
Same back controls (joystick, click wheel, etc.) as 5DIII;
Fixed back screen (not tilting);
Video enhancements that I don't understand and won't use.

That about covers it.

Totally agree. Exactly my expectation. It might have abuilt-in RT speedlite trigger as a surprise extra deature (that would sell an extra couple 1000 of 600EX-RT speedlites!) - in line with the 7D which was the first EOS with pop-up flash serving as optical speedlite trigger.

I won't allow for smaller lenses as the image circle still needs to be the same size.

of course it would. Even in TWO ways:
1) If the claims about increased sensitivity by factors 1.4 in the center and factor 2.0 at the edges are true, front elements would be considerably smaller at to get the same transmission -> smaller diameter
2) a LOT less correcting glass eleements required in lenses -> shorter lenses
Tiny f/1.2 FF PANCAKE lenses all over.  8)

Canon might be ready to switch obver their current sensor fab and introduce a new lineup by 2099 already. :-)
But Sony could easily jettison their just-started FE lens lineup and replace it with something new, starting tomorrow. As long as the new lenses are Zeiss-labeled ...   :P
