Lenses / Re: Mt Yasur, Vanuatu lens advice
« on: June 17, 2014, 07:05:48 AM »
I've not been there, but it certainly looks like an interesting place to see.

I'd guess a 24-105 should be sufficient ... unless there's even more volcanic activity than here ... then I#d want a longish tele lens.  :P

Sony sells a BUTT LOAD of their similarly spec'd lens because it's a kit lens, bundled with their cameras. That's exactly what Canon was going for. And they're smart to do so.

yes, Canon would be smart to also sell a CAMERA to go with this "kit lens".  ;D

For the U.S: Canon might not be selling this lens AT ALL.   ;)

Now we have a price for Europe:  € 329,-
http://www.photoscala.de/Artikel/EF-M-45-6355-200-mm-IS-STM

If optical performance is on par with the EF-S 55-250 STM, then it is well worth the money.
Provided, one cares for a f/4.5-6.3 lens ... with only 1 dated camera body available to mount it on. :-)

Overall a good sign, meaning Canon has not given up on EOS-M system yet.
Will be interesting to see, what Canon's will do regarding their mirrorless APS-C offering ... 

1. Will the EF-M 55-200 be offered in US?
The lens is featured on the Canon Europe homepage and on Japan, China and other Asian homepages. But not (yet?) on US homepage.
We will know the answer quite soon.

2. Will EOS M2 be offered in Europe too? In US?
Currently open to anybody's guess. Personally, I don't think so.

3. Will there be an M3?
same thing as now, just with DPAF 70D sensor + AF?
Or higher end, with EVF ... as a fully capable Fuji XT-1 competitor?
and when?
And if so ... will it be offered in Japan/China only? Or Asia? Europe? US?

My best case scenario would be a surprise "killer EOS-M3" announced in August/for photokina ... fully competitive mirrorless APS-C body [+system] in terms of sensor, AF performance, EVF, battery charge. Don't think it will happen, though. More likely, Canon will continue to snooze and lose ... and continue to watch how Sony and Fuji are nibbling away at their APS-C market share. :-)

To get to clean, high ISOs, you need larger and fewer pixels. To get high resolution, you need more pixels, but the trade-off will be high ISO performance. If you want a reasonable compromise, you go somewhere in the middle.

High megapixels, low noise, High ISOs – regardless of the brand of sensor, you can have two of those things, but never all three.

Unfortunately only true for today's Canon sensors.

All other manfufacturers are proving, that a good sensor design and good electronics behind it cause only minimal hits in Hi-ISO performance (mainly at ludicrously high ISOs beyond 6400) despite hi rez.

Michael Reichmann in his LL review of the A7s comes to the same conclusion:
12 MP A7s has onöly a tiny Hi-ISO advantage over 36 MP A7R ... in practive only relevant from ISO 6400 upwards.

I would be more than happy to give up 1 stop nosie advantage from 6400 upwards .. if I could get a Canon 36+ MP camera with D800E performance  ... in a mirrorless cam ... sized and priced like the Sony A7R. :-)

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. :-)

EOS Bodies / Re: A Few EOS 7D Mark II Specs [CR1]

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

59
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.  ;)
