This also plays out in the overall upgrade strategy that Canon appears to be following.  One area you see that is the AF systems chosen for the non-1-series bodies, where improvements are slow to 'trickle down' the lines.

I think body strategy regarding AF is one of the strong points of Nikon vs. Canon.  Nikon has more of a gradient for AF performance across it's line, with each body (more or less) inheriting the AF system of the next higher model's previous generation.  With Canon there are large steps in AF performance.  Even the 7D with it's highly regarded AF system is only comparable to the 1D2 maybe the 1D2N (from what I've read, I haven't used either).

Lenses / Re: Canon price increase enforcement
« on: March 27, 2011, 12:04:34 AM »

Please tell me your sources for this information.

There are no L lenses being made at all. Where does this fact come from?

Lenses are in limited supply. How limited? Who reported this?


All L lenses are manufactured in Canon's Japanese factories.  All Canon's Japanese factories are currently closed.

Therefore, no L lenses are being manufactured right now.

EOS Bodies / Re: Resolving Power on the 5D Mk II / III

im personally waiting for thr 5DMkIII. i am in no rush and i can wait. more time to save up since i only have 2k.

I am/was also waiting for the 5D3 to be released; but with all the uncertainty with what's going on in Japan, on top of the uncertainty inherent to trying to make decisions based on rumors, I gave up waiting.

Ok, I didn't exactly give up.  I just came to the realization that it will probably be a year before the 5D3 comes out, and acted accordingly.  So last night I ordered a 60D, and with the difference I'll get a lens or two.  Then next year, or whenever the 5D3 comes out, I'll pick one up.

Doug,

Thanks for dropping all this knowledge on us.  You are a true asset to the CR forum community.

Looking good.  What lenses did you use?

...unless it's a "square full frame" AKA 36mm x 36mm...

A mirror that can cover a 36mm sensor would need to be at least 50.91mm tall.  The film plane to flange distance on the EF mount is only 44mm.  You would have to go mirror-less to do a FF square sensor.

Software & Accessories / Re: Yongnuo ST-E2 vs Canon ST-E2

I tried the eneloops and also some Costco alkaline batteries, same result with both. The eneloops are recommended in Syl Arena's book which is why I use them, but maybe there are better ones out there. The 2CR5 in the canon unit is 6V however, and as it is a lithium battery, I guess it probably has more oomph than NiMH.

My first instinct on battery selection for a ST-E2 clone that takes AAs would be eneloops.  It's something that should be low drain.  If fresh alkaline batteries didn't make a difference (higher voltage, 1.5v vs. 1.2v, current when new is comparable to a mid-grade NIMH), then I doubt higher current NIMH cells will change much either, but it's worth a shot if you happen to have them.

Most likely though, it's just a design limitation.  You have to cut more than just profit margin to get something down in price that far, design and component quality are the only places it can come from.

I know eneloops are no good in a flashgun

I didn't know that. I've been using them in my 550EX's and 580EX2 for years.

Try some low internal resistance NIMH cells some time, they have a higher capacity, and can supply more current.  Your flashes will cycle significantly faster.  Only downside is relatively fast self discharge rate.  Let them sit for a month and they will be half dead (actually closer to 25% a month self discharge). For anything that will be sitting for months with relatively little usage, like a remote control, use eneloops; I have a few sets, they're great.  For high drain uses, like flashguns, there are better alternatives.

Nice writeup.

I find the recycle times being an issue really odd.  Do you have any low internal resistance NIMH cells to test with (like PowerEx, etc)?  They can provide a lot more current than high internal resistance cells like the eneloops can.  I know eneloops are no good in a flashgun, and while I wouldn't expect the ST-E2 to need high current like a speedlight, it's worth a shot.

Canon General / Re: Canon falling behind in sensor performance

Canon and Nikon really are a horse a piece.  Each has their strengths and weaknesses, but they both have good SYSTEMS as a whole.

Sony could have the greatest sensors in the world, but they don't have lenses, they don't have flashes, and they don't have third party support.  In the current market, I could never recommend that someone buy a Sony dslr, no matter how good the sensor tests in DXO.

OK, just browsed their more-fancy-than-functional website, there is more depth to their lineup than last time I looked; so I'll gladly eat crow on that one...

...still wouldn't buy one though.

Commitment to the market is a good point.  Sony has a long history of coming up with proprietary versions of standard technologies (DAT, Mini-disk, ATRAC, Memory Stick, HiFD, UMD, SACD, BETA, etc.); and dumping them when they don't take off as well as hoped.  They also have a recent incident of being hostile towards customers (rootkit fiasco).

It could be a loose shim on the image sensor's trans-nebulizer - probably caused by the higher than normal gravity we have recently experienced from the "super moon". It should settle back into place in a few days. ;)

Is that a single exposure?

That looks great.

I've never tried video, but I think shooting stills at a bowling ally is much more technically challenging than even the worst lit wedding.  The difference in light levels between on the lane, and off the lane (or even just on the approach/skirt) is HUGE.  If you could use a flash it would be easy, but without, it's nearly impossible to keep the background from being severely (or at least distractingly) overexposed, and have the bowler properly exposed.

It's probably an artifact of the demosaicing process that converts the raw output of the bayer type sensor to RGB pixels as we know them.

In fill mode the camera will meter primarily on available light, and use the flash for fill.  (still put FEC to -1)

With my 5DII and a Speedlite, my decision is not whether to apply a negative FEC, but how much negative FEC to apply...usually anywhere from 2/3 to 1.5 stops.

I use -1 as my starting point, and that's where it stays 90% of the time.  The only time I've really had to change it is if I'm bouncing off a colored wall, and it's metering funny; or if I need to overpower a mixed light source.
