EOS Bodies - For Stills / Re: Canon EOS M System Announced
« on: July 23, 2012, 06:33:33 AM »
In addition to the two lenses, any of Canon’s EF and EF-S lenses can be used with the EOS M with the optional Mount Adapter EF-EOS M.

Just thinking - this makes for an expensive lens cap!

I've been deriding the look of the Sony NEX camera but when I tried holding it (the 5N and 7), they feel good not awkward.

Looking at the pictures today (especially with the 18-55mm lenses), I realized that the Canon mirrorless look only slightly better than the NEX but will possibly not as well due to the almost non-existent grip.

Oh, and it seems too expensive for the features
Perhaps we are misunderstanding the intended market position?
I think this might be (with the 22mm STM kit lens) - a photojournalism camera.
Maybe Canon are pitching this as a competitor to the Leica M9?
If so, then it's attractively priced!  ;)

Software & Accessories / Re: Circular polarizer on a UWA lens
« on: July 19, 2012, 09:03:57 PM »
I've been seeing conflicting opinions on whether or not to use a polarizer on a wide angle lens.  I've seen alot of reviews where people mention that because of the wide DOF, you'll uneven light levels across the scene when using a circular polarizer.  But then on the other hand I see other blogs where people say the complete opposite, that for taking photos of landscapes it is a must.

Can anyone shed some light on what the issues are and when it's ok to use a polarizer on a UWA lens.  Specifically thinking about the 16-35L
I like to use a Circular polarizer for landscapes too - it certainly helps with sky and clouds, as well as situations where reflections on water or windows is to be minimized.
I have found that using a UWA lens (mine is a 16-35 2.8L II) on a crop body (50D) I get uneven color toning at wide angles due to the geometry of the lens and the way light passes through it.
I've also heard that on a FF body the effect is more noticeable because you get the entire image from the lens, not just the cropped portion in the center.

So - should you go for a CP on an UWA lens for landscapes?
Depends on
  • Crop factor (FF vs APS-x)
  • Lens quality & Focal-length(vignetting)
  • Filter quality (thin filters better than thick)
  • What you are trying to achieve, generally.

You might be able to achieve more dramatic effects, with a better result by managing exposure and using post-processing instead.

Your mileage will vary.

EOS Bodies / Re: Should/can Canon keep making its own sensors?
« on: July 18, 2012, 02:20:51 AM »
It may have been said before, however the incredibly obvious needs to be said IMO...
  • Should Canon do/make/(insert your pet peeve here...)? - that's what they pay their business executives to make decisions about.
  • If you want to influence that decision, you have simple and easy choices by voting with your wallet.
  • Either buy the stuff they make that fits your situation and needs, or
  • Buy the stuff someone else makes that fits your situation and needs

Canon would get that message much more effectively than any amount of speculation or ranting from this community about what they should do.

There's no point speculating / pontificating on what Canon should / could do - unless you work for Canon, and then that forum should not be visible here.

I'm quite sure Canon have good methods for gathering market intelligence about what the market requires - how they execute that strategy is their business, not ours.

Just saying... (I don't work for Canon or any affiliate)  ;)

Craig,
My most heartfelt condolences on your tragic loss.

Hi folks,
I already have a 580EXII and an older 420EX, and wanted a second 580EXII - but they have disappeared (now that Canon has withdrawn the 580EXII from sale and offers only the better and much more expensive 600EX).

I just thought I'd share some experiences having just purchased a Chinese-made 'compatible' speedlite.
I didn't want to pay too much, and the economics (AUD199) were compelling so I thought I'd give it a go.

The unit in question is the Yongnuo Speedlite  YN565EX - and claims to be compatible with and largely equivalent to the Canon Speedlite 580EXII when used on qualified cameras (e.g. a 50D like mine).
It's made in China (allegedly by the people who made the 580EXII for Canon under contract, or so the local sales agent told me).

I suspect that it may be marketed under different names in other countries.

Here's my observations.
  • Yes, it's (mostly) compatible. There's a Canon version and a Nikon version
  • You can drive the C.Fn and operational functions like a 580EXII from the menu of a compatible camera like a 50D or later
  • It works OK as a wireless (infrared) slave to a 580EXII or STE2
  • The metering and controls are much the same, except that it's ETTL not ETTL2 - at least the bit that's not the same is the lack of high-speed flash sync
  • It lacks the nice rubber weather sealing on the hotshoe mount that exists on the 580EXII, as well as not having the lever-latch for hotshoe
  • One bonus - you get a manual that's in Chinese as well as English! ;)

Lenses / Re: Canon EF 40mm f/2.8 Pancake
« on: June 29, 2012, 09:37:13 AM »
It is quiet but not silent. It is more accurate than the 50 f/1.4 and doesn't do the minor adjustments - it just rolls up to the focus point and stopn - perfect for AF in video where AF jiggling is very irritating
I'm pretty sure the claim for "silent focus, good for video use" is qualified ONLY for the EOS 650 / T4i - since half of the 'quiet' autofocus technology is embedded in that camera body - and it's the combination of that camera body's CD/PD autofocus capability, the firmware and the STM lens that makes it silent.
At least, that's what the marketecture says..

Hi,
The Australian support site for Canon lists the Windows 7-compatible codec here:

Note: this coded is not supported in 64-bit mode (what a pity!  :( )

Third Party Manufacturers / Re: Manfrotto tripod
« on: June 13, 2012, 04:12:48 AM »

Are you saying you wouldn't expect a lower-line tripod from a major brand to last more than a couple of weeks?

Yes, if the major brands clearly states that it supports up to 1Kg/2.2lbs and you load a lot more weight on it.
In Australia the Consumer laws are clear - the concept of 'merchantability' applies to provide a statutory implied warranty - so unless you really exceeded the load specification, it is the manufacturer's responsibility that any product should be made well enough that a consumer could expect a reasonable service life (not measured in days or weeks).
The remedy for the consumer would be to return the defective goods to the retailer / point of purchase  (not the manufacturer).
Your mileage in other countries will vary.
Off-topic - could this be a reason for the price variation between countries ("grey market") - to cover cost of warranty in Australia?

This also means better repeatability; and less human error in the manufacturing process; important as DSLRs continue to become more and more high performance, requiring ever tighter tolerances.
Not to mention the fact that Japan's population is aging fast (in Japan they now sell more adult diapers than infant ones) - so the pool of talent that can make things by hand is diminishing fast.
The only human 'touch' of next-gen Canon cameras in 10 years time will be that of the designer.

I like 'industrial grunge' photos. This one is the door of a dilapidated vault in the Rookwood Necropolis in Sydney, Australia.
Hand-held - mid afternoon at about 5m distance. I was experimenting with shallow DoF. The focus is on the handle.
