To be followed by an announcement from Sigma of an 85mm 1.4 Art for a quarter the price and 90% the IQ.

Very much wishing so here.

Does any body know about the 1d owners club? I was looking at the Hong Kong Canon web site to look for any announcements and ran across a spot on their site pointing out the benefits for all 1d owners from 1dc to the original 1d. It seems to be tied to Canon professional services with things like up to 50 percent studio rental discount and express costumer service among other things but when I went to the USA website I didn't see anything. I'm a new 1d owner so it would be cool but not really a big deal, just curious.

...I had a Ford F-150 that had all the window regulators fail (4 of them) and Ford didn't pay a dime, I did. It was a known problem on all 2004-2007 F-150s. I got stuck replacing them all plus a third one on the driver’s window at a cost of $1K out of my pocket....

Umm, interesting. I had a Ford Expedition ('01) that developed a head gasket leak because of a well documented issue with the passenger side head (all over the net). The head was not milled flat and had a slight gash in it from the machining process and over time the head developed a leak. I was loosing about 2 quarts before an oil change. There was a service bulletin, but no recall. If you were outside warranty, tough. I promised myself that I would never buy another Ford SUV. I went Toyota and happy as a clam - so far.

I hope Canon is not treating it's customers this way. If so, I smell a potential class action lawsuit or worse the defect of loyal customers.

Little chance serious canon customers will defect. The other side of the fence is worse. Your warranty info is always available up front before you make a purchase. After that you are always on your own with any company and any product. Little chance for a class action. Now if its still under warranty and it fails then you have a case. However all of the wining ive seen here is about after warranty service.

And the warranty covers product materials and workmanship for 1 year usually. The key words here are materials and workmanship. Any design flaw is considered workmanship and covered under the warranty period.

As far as the ford goes...they are designed to leak right off the dealers lot. If you fix them all, the engine explodes.

Laptops and cell phones eat batteries during testing, too. Whenever you're working with software, there's a good chance you're going to have bugs that cause excessive CPU utilization. Any time the CPU is doing work, it is consuming a lot more power than when it is idle. It only takes a tiny bit of activity every few milliseconds to seriously impact power consumption by preventing the CPU from ever reaching an idle state.

Hopefully, those bugs get fixed before the thing ships, but it isn't at all uncommon to have them during development. I'd be really surprised if anything other than the CPU were responsible for the high battery drain.

Well, Intel's CPUs generally use less power than AMD's CPUs.

Click to expand...

Intel has greater IPC (instructions per clock) than similar level AMD CPUs at the same clock speed. More complicated than that, but basically Intel CPUs of similar generation as an AMD CPU at the same clock speed will do a good bit more work than the AMD CPU does. This lets the Intel CPU do a "race to sleep", which is to say get the CPU back to it's lowest power usage state. If a bit of software keeps the CPU active, even at low levels, it ends up using quite a bit more power than it does if it can if it is in it's lowest power state (at which point it's not really doing much at all).

Like dgatwood said, a tiny bit of activity every few (or even more often) milliseconds can result in the CPU staying at a higher power state longer than it otherwise should, and using much more power than it would otherwise. Also, don't forget that when it uses more power, it's also using part of that to generate waste heat. I don't know the formula, but I believe, in general, as the power usage goes up, for the same conductor efficiency goes down and more of the power is released as waste heat, rather than getting to where the work needs to get done.

Exactly.

There is absolutely no reason the Canon 5D MkIII should not be able to record 1080p @ 60fps. The Digic V has sufficient processing power. 1080/60p would most likely have to be limited to IPB compression though, as ALL-I would require a sustained write speed of about 23MB/sec.

Has anyone taken a look at the Sony a77?

It's a $1400 body with a 24.3MP sensor.
It records 1080/60p/60i/30p/24p and does so with an inferior processor to the 5D3.

It's simply a limitation of firmware. Canon purposely crippled the camera to protect their higher end models (which most considering the 5D3 can't afford anyway). It's not like people in the professional market would stop buying C300s, C500s, and 1DCs if the 5D had more advanced video features. The pros are still going to buy the dedicated cinema cameras for the expandability, advanced manual controls, and I/O features (HD-SDI, XLR, Genlock, Timecode).

And yes, I realize the 5D3 is a photo camera first, but 1080/60p is not something that would handicap, or take away from its photo abilities. It wouldn't even cost extra!

There is a reason. The 5D is designed to use the hardware encoder in the DIGIC 5 chip, and that encoder does not do H.264 60p. If you want hardware encoding at 60p you need the DIGIC 6 or DIGIC DV 4 chips, which the 5D3 does not have.

Perhaps, but I still love steam locomotives !

Click to expand...

Then you'll love this:

Norfolk & Western J 611 is a J-class locomotive built in 1950 in the town where my family has lived for 4 generations. She is the ultimate development of the steam locomotive, having a cruising speed of 110mph with 15 passenger cars. She is also breathtakingly beautiful, the streamlining being part of the key to her speed.

She'd been sitting the in the VA transportation museum since 1995, but a group of concerned citizens have pulled together the money to have her restored to operating condition, starting this month. If all goes according to plan she'll be making the rounds around the eastern USA as part of N&W's 21st century steam program sometime in 2015.

The Deutsche Bahn Class 44 steam loco has been my favourite steam loco.

This would have been a shut up and take my money moment until I saw that sync speed.

Why? Light it with HMI's or LED's and roll with it.

Click to expand...

For HMI - That Arrimax isn't exactly portable, esp. not if you figure in its power supply. Or cheap, they cost much more then the leaf shutter capable alternatives. And thats if you need just one.
And LED? How exactly do you want to put ~200klx on your subject with those? Preferable from a reasonable distance. A superdino suddenly seems tame, and the few dollars for the LS turn out to be a bargain.

A superdino? I've never seen one before but that looks awesome! And yes, LEDs aren't quite there yet in terms of overpowering the sun.

I have to say that when shooting the Canon 100mm macro lens or the Zeiss Otus lens on my Canon 1D-X, I never pay attention to anything that would indicate perfect focus on the camera for a manual focus lens. Sometimes I will go into live view and zoom in but then leave live view and go back to the viewfinder to make sure the focus is where I want it.

Manual focusing after a while becomes almost second nature and you know when it it right. My success rate increases the more I shoot in manual focus.

I find the 7D screen is not aggressive enough for good focus. Do you use 1DX standard screen?
Yes I think focus of Otus lenses have a major need for ultra-precise focusing. No one will pay Otus price to sacrifice sharpness with slightly off focus.

I'm not a pro, but thought a 24 / 1.4 lens was more aimed at:

Astro

Concert/stage photography

Environmental portraiture

Reportage

More importantly, I thought landscape guys avoided such lenses for flare and (lack of) sharpness issues.

- A

Yes, that's correct, although it makes for a really nice landscape lens because it's so sharp when stopped down. Since getting the 24-70II and TS-E 24, I don't use it much for landscape and use it for the purposes you listed above where it excels at all but the astro. The lens has a lot of coma in the corners at f/1.4 and even f/2 which spoils things.

I don't understand what you mean by optical-pulse set of facilities. If you have three 622 you wouldn't use Canon's RT at all, you'd just use the Yongnuo.

Click to expand...

Exactly my point. The 622's will control the 600EX and the 580EX, no need to use Canon's RT at all. Love the 622s, they're cheap, feature-rich, and work very well. Saves me from having to sell the 580EX-II and buy another 600EX-RT.

And they work with my 430EX and YN565 in TTL, as well as my two YN manual only flashes. The 600s are great, if you have a whole set of 600s, but there's no flexibility.

I also bought mine at the beginning oh this year and Bridge doesn't recognise the right serial number. The first two digits are 10, which should mean that it was produced in October 2013 (at least this chart is true - http://www.the-digital-picture.com/Canon-Lenses/Canon-Lens-Aging.aspx)

That was about as expected. Image quality apparently very good, but it does seem to have AF issues. That may well be Sigmas achilles ... Never the less, I am looking forward to get my hands on it!

Eldar, the good news is that you will be able to blame the Sigma for out of focus shots - something that's a bit harder to do with your Otus

Looking through the photos he posted, the out of focus rate is almost 50/50 ???

He he, I do have problems with getting focus right whenever a light source is involved

"Delighting you always" is what they went with for a slogan as "Delighting you as infrequently as possible" was already taken.

I want this announcement to be something pricey that I don't need. I will then rant for days about how Canon built the wrong pricey thing as it was not the pricey thing I needed.

And then we'll discuss a nuts rumor about how the words 'need' and 'want' mean two different things.

Blasphemy!! Do these testers not comprehend the paramount importance of dynamic range? WTF?!?

Oh, wait…you said they compared cameras, not just the sensors in them. How very DRoll.

Hi Nate
When you say it's in Auto, I am assuming you are not meaning the Green square Auto mode? You won't have any control over the AF in that mode.
In AV, TV, M mode, you should be able to switch between the modes by pressing the AF button on the top, back right of your camera body, and then immediately pressing the small, m.Fn button above the shutter, which should cycle you through the different AF areas. You can choose with button or control to use for switching between the modes, in Autofocus menu AF4, AF Area Selection Method. Go into that option and choose whether to use the M.Fn button or the Main Dial.
Hope that helps
cheers
Grant

Works!
On my 7D I changed it from the quick menu, and here I never bothered to change it and now when I wanted I couldn't make it work. Anyway thank you!

The white 40-STM (and the picture) is not mine, I saw it in the "40 STM" group on Flickr, that I am a member of. My own 40-STM is black, as well as the 100D.

But it's a real Canon product. The white 40 STM is offered in a kit together with a white 100D in Japan. The kit was launched late last year:
http://www.ephotozine.com/article/white-canon-eos-100d-launched-23443

In Europe I have not seen the white 40 STM in stores (separately or in a kit). I do think the white version looks like a "tongue in cheek" statement to a tiny "L" lens, not to be taken too seriously.

Since bokeh is the correlation of sensor size, aperture and distance to subject- we should know all these things based on the sensor readout.

Nope, there's your problem - the camera only knows the distance to the focused object from the af system, everything else is 2d. To any fancy calculations based on distance like bokeh, you'd need to know real 3d information and generate a depth map - probably then you'd be able to simulate different aperture sizes in post, most likely in the small->large direction.

I bought a 400 5.6 for my 600d and I haven't noticed the lack of IS. OK, I live in a sunny country, but the autofocus on the 600 isn't exactly stellar, nor the iso performance, and I haven't had any problems. I mostly get away with 1/1250-1/1600 at f5.6-7.1 and iso under 800. For me, not having to fuss over zooming makes my life easier, as there are fewer options for composition, which is what I need with quick moving animals. (It's fun for surfing portraits too! 1/1200, 5.6, 400)
I bought the lens second hand for a very good price, too, cheaper than I could buy the Tamron...

Excellent shots, love the light in the second one!

CarlMillerPhoto · Apr 21, 2014

As long as Canon puts out a 50 prime with IS I agree with the consensus, it doesn't really matter what else is on the market. But, it does need to be f/2 or faster if Canon wants professionals and video people to pick it up. A 50mm f/2.8 IS won't make it into the bag of many who are getting paid to use their camera.

No idea. We have a lot of ants around here, I live in a bush area. I'm diabetic so used to carry a muesli bar in my bag so maybe that attracted them. It was sealed in it's packet though and I have never had ants around any of the other snacks I have secreted around the place.

I think I have evicted most of them as I haven't spotted any for a while now - I sat with my wife's point and shoot to get the video craved by earlier posters and failed to see any.

Given that I only ever saw them externally on the camera or in the viewfinder I guess it does speak well for the weather sealing. No ants ever made it into the main part of the camera despite nesting next door.

JohnDizzo15 · Apr 21, 2014

One more at 2.8. Same shutter and ISO as the others.
