Lenses / Re: Why do fast primes not have IS?
« on: June 25, 2014, 07:28:32 AM »
And If I had enough money for the 24-70L 2.8 II then I would preferably take this one instead of its prototype brother with IS because of size and weight.

urban legend ... just look at the difference in size and weight between EF 70-200/4 L vs. 70-200/4 L IS ... identical in size, 55 grams more weight. And ... even better IQ for the IS version. :-)

4 L     ... 76x172mm -  705g
4 L IS ... 76x172mm - 760g

Other than for Super-Teles with huge glass elements, in-lens IS units are quite light, compact do not add a lot of production cost ... although it may add a lot on retail prices.  ;-)

yes, agreed.  :)

I've sold my 2 "fast" primes [50/1.4, 100/2.0] recently and rely solely on my f/2.8 workhorse Zooms [17-55, 70-22 II].  Occasionally I do like the capability for shallow(er) DOF (on APS-C), but got sick and tired of the very high amounts of loCA (bokeh fringing; purple/green) of these old lens designs ... and am not prepared to shell out a grand or more for optically better fast primes [L]. 
IF I move to FF and stick with Canon, I'll definitely get the 24-70 2.8 II as well. Although IS would really be welcome on that one, too!  ;)

Canon used the 7D as a development mule for camera ergonomics and User Interface updates, which is why the camera's handling is still so fresh. Nearly all of it's design changes went into the 5DIII and 1DX. So much so many people called the 5DIII a full frame 7D than a 5DII replacement (which is what the 6D eventually became). The AF redesign paved the way for the 61 point array and control and apart from the sensor, there is still a lot to like about the 7D. So it makes sense for Canon to use the 7DII as a development tool to updaqte the sensor technology and design. As long as the 7DII breaks even in the market place then the develeopment and lessons learnt from this model are effectively free to Canon, who can then incorporate it's features into the next gen of camera models...ie 5D4, 6DII, 1DXII ect. If the sensor is fantastic, then it's hype will generate a natural desire for full frame variants...and the next gen camera models will pretty much sell themselves with little marketing. In my view, that's the wise application of innovation which leads to market dominance.
If I rememebr the 40D introduced Live view to Canon, which was later incorporated into the 1DsIII and 5DII models. For landscape work, it was a game changer...somehitng which Nikon have never fully engaged with.

+1 ... on eyerything!

I have a 400mm f2.8 LIS. It's a fast prime and it's got an image stabiliser.
I have a 24mm f1.4 L, it doesn't need and IS unit because it can be shot hand held at 1/25th second easily and due to it's huge light gathering capabilities, it can shoot at light levels several stops below what an f2.8 lens can achieve. So what could an Is offer a 24mm f1.4? Very little.

2 stops [2.8 - 2.0 - 1.4]  ... to be precise.  ;D

IS would not hurt, even on f/1.4 lenses. Not everyone shoots them fully open ALL the time. Sometimes a bit more DOF is desirable. Or 2 stops closed (f/2.8) for IQ. etc.

With FF mirrorless cameras taking over some time soon (I hope  ;) ), in-lens IS loses one of it's two advantages over in-body IS: on an EVF, viewfinder image will be stabilized, irrespective of whether IS is implemented in-lens, in-body .. or even in a dual/hybrid way using both. [Second advantage for in-lens IS being the fact that it's specifically tailored to match a specific lens ... and I do not believe this holds much truth any longer against todays in-body IS systems)

So while Canon (and Nikon) had a major advantage with their in-lens IS approach during the (D)SLR era, this is coming to an end.

Personally, I would prefer a Canon FF mirrorless system, of course with new, native, short flange-distance lens mount. Ideally with in-body IS, and lenses without any manual focus gears, only "by-wire" in a really well-implemented fashion. Zoom also "by wire". Either turning rings on lenses or really good, highly ergonomical control points on camera body. Ideally also with non-mechanical aperture ... think of something like a variable, highly transmissive LCD with a perfectly round aperture opening at all openings .. also implemented in body, rather than in evry lens.

To complete my vision of future "solid state" mechanics-free FF-sensored cameras, shutter would be fully electronic.

If the in-body IS could be extended to "6 axis", i.e. adding linear movement in the Z-axis [current 5-axis systems (Oly) allow linear and rotational moves in the X and Y axis and rotational moves around the Z axis] ... then focussing could possibly also take place in the body, without any moving lens elements. With proper lens construction, that is.

This would possibly allow for camera/lens systems with significantly smaller, lighter, simpler, more robust, fully weathersealed, higher IQ [only needs to be adjusted/centered once before leaving factory] lenses ... at significantly lower production cost ... and hopefully prices.  8)

Not sure however, whether I'll live long enough to get it from Canon.  :P

Meanwhile I do expect Canon to come up with in-lens IS in fast primes as well. 50/1.4, 50/1.8, 85/1.8 + 100/2.0 are all very old lens designs and in need of a major overhaul, with the same treatment Canon gave the 24/28/35 IS primes. Not only IS and (corner) sharpness, but also less (lonigtudinal) CAs, please.

EOS-M / Re: How do you carry your EOS-M?

Recently bought a Hama Nashville 130 bag @ € 30 or so.

It fits a larger M-Kit ... body + 18-55 + 22/2 + EF-S 55-250 STM with adapter attached.
There is still room for an 11-22 :-)

Instead of the 55-250 telezoom there would also be room for a speedlite .. 430 fits easily; 600EX only folded up

If I get round to take some pics of bag with content I'll do so.

EOS-M / Re: Is there a group anywhere of eos m owners?
« on: June 24, 2014, 07:30:17 PM »
... eos m. I have it since a week ...

Hello and welcome to "the M club" here. :-)

What lens/es do you use with your EOS-M?  EF-M  or also EF-S/EF via adapter?

Myself I got my M for about 1 month now. It's my light and compact "go everywhere camera".
ALso got the EF-M 18-55 kit zoom, EF-M 22/2.0 and EF/-M adapter, which I use fairly regularly to connect my EF-S 55-250 STM and EF 40/2.8 STM (pancake) and sometimes my EF-S 10-22 and EF-S 60/2.8 Macro.

In my experience, lenses with STM AF drive work better on the EOS-M  than EF/EF-S lenses with USM AF which was optimized for DSLR phase AF.

In preparation for the introduction of the 7D Mark II I already have buyers for my 7D. Based on the technlogies in the 1D X, 5D3, 6D, 70D, 700D, 100D, 1200D and even M2 it will be flagship APS-C body with all the technological trimmings one could ever wish for. It will outdo anything Nikon or Sony has in the market.

LOL.  ;D

Solid rumours I'd put any money on come along very rarely. I personally discount almost anything that's more than 4 months out from an announcement.

I still can't fathom why the camera makers are so secretive, when companies like Intel and Microsoft provide roadmaps into future announcements.


Actually most camera makers are handing out roadmaps when they announce new camera/lens systems like EOS-M and EF-M.

Definitely Fuji (X-mount), Panasonic (mFT), Olympus (FT and mFT), Samsung (NX), Sony (NEX/E-mount and A7/FE-mount) have done so.   

Nikon, Canon and Leica however are totally caught up in customer-unfriendly, arrogant behavioral patterns. 

EOS-M / Re: Which batteries do you use on Speedlite Flash 90ex?
« on: June 23, 2014, 11:04:57 AM »
eneloop AAA, beacuse they keep their charge much longer than regular NiMh rechargables. Especially since I use that small flash thing only very infrequently.

... On the one hand, it's very difficult to imagine any 7DII advancement of that magnitude. On the other hand, it's always risky to bet against the future when it comes to technological advancements.

I will hope we see that kind of advancement, but I will bet that we won't.

well, 24 MP at least 1 stop improvement for Noise, Banding and DR ... throughout entire ISO Range should be simple enough ... otherwise Canon should just purchase Nikon 7100 from Toshiba and put DPAF in an improved version (vs. 70D) on it. :-)

We shall see ...  ;D

"Global launch" of a product ... except U.S. ... does not happen very often ... a bit like "semi pregnant" :-)

Hehe!  ;D

Wow, now its clear: global launch of a new Canon lens ... Japan, all of Asia, all of Europe, Australia, New Zealand, all of South America, all of North America  ... minus the US.

All of you "not more than 299 dollars for the full EOS-M kit Yanks" must really have caused some hard feelings in Tokyo. They won't give you new EF-M toys any more. No, no, no ... You've been bad and Canon will punish you. Fat mirrorslappers is all you'll be served for dinner from now on.


PS: how stupid and shortsighted a "strategy" ...
