Canon General / Re: Lost inspiration
« on: July 11, 2013, 08:01:20 AM »
I have just moved continent, from Asia back to Europe. We've been home for just about a month now and I have barely touched my camera since. As my identity here indicates photography is a hobby, not my profession. I normally like portraits and street/travel.

Before you went to Asia, were you doing a lot of photography?

My guess is that since moving back "home", you've reverted to your "home self" which existed prior to photography.

Street photography is worthwhile in Asia because more people are outside and on the streets. In Europe and the USA, the streets are almost deserted (by comparison) unless you are in a big city downtown area. This means there is less subject matter to start with unless you go to the poorer countries in Europe (Romania might be interesting, Turkey another.)

The easiest way to reignite part of your passion is to travel around Europe. Go to places you haven't been before. Try to find a theme to pursue in all of the local towns or all of the towns within 50-100km. That'll get you out and traveling. Try something like taking photographs of all the pubs within said distance.

Street & City / Re: video of photographer getting his lens stolen

Lessons:
1) don't let people crowd around you
2) hold onto your camera by the lens
3) backpacks put valuables in your blind spot

The modus operandi here of the street thieves is a well documented practice: present cardboard/papers up to a person's chest and let your hands go to work below the cardboard. Pockets for wallets used to be the common target. Lenses from DSLRs make a new, easy target.

I've seen gypsies in places like Florence try to use this exact tactic where there is a mother + children roaming for prey.

But really the problem here is (1) - he let himself get surrounded and was thus in a situation he could not hope to control or survey. I can't tell if he knew he was a target but if he did know then he should really have thought more about what was valuable to him.

When walking around cities where I have reason to be careful, my camera and camera bag are cross strapped, one for each hip and a hand is always on each. The only time I use a backpack for camera gear is hiking.

I think people are missing my point.  All I was saying is that there are some things that can be changed much closer to the release of the product than others.  I never said anything about changing hardware (electronic or otherwise).

Like what, exactly?

Quote
If they have any freedom in modifying the design when they get close to release (again, before printing manuals, boxes, etc.) it is in the firmware.  And I still believe it is easier to dial back some functionality (like fps) than it is to improve it.

I'm pretty sure that all of the primary features are agreed upon and nailed down well in advance.

About the only thing that I could see them adding "late" would be "more high ISO" that is really noisy.

If someone thought that adding in a 14fps mode to top the 12fps mode with a few months left until announce and did so, I'm pretty sure they'd be kicked out the door.

Consider that it was 3 years from the release of the 7D in 2009 to firmware version 2.0 in 2012.

There are lots of people that think they know what it means to write software and/or build electronics hardware. Few indeed that understand what it takes to deliver such a product that is of a high enough quality standard to command the price of DSLRs.

Lenses / Re: 50 F1.4 durabilty question

This problem is so common that one camera/lens cleaning/repair place I went to, the ladies at the desk knew what the problem was and how much it was to fix without looking in their computers.

1445
Also related, i was in a cam shop to pick up the eos m, and the camera guy had a ball telling me that "canon is bringing out a lot of stuff later this year" Of course nothing specific, but that does coincide with the current M firesale, even mentioned by this latest post.

Yeah, those salespeople in camera shops...they have all the inside information, direct from Canon HQ.   ::)

All that they need to do is read canonrumors 'cause everyone knows we get it direct from Canon HQ!

1446
Why do they keep selling the cameras in bundles like this?  Why not just offer a good price on the camera, and not add in all that "bonus" crap that we have to pay extra for in terms of shipping costs, extra taxes and environmental fees, duty and brokerage charges?  It all gets tossed into a dumpster because it's worthless crap. (which I guess is why they have to give it away in the first place...)  Maybe they're just hoping to appeal to the last vestiges of the Walmart mentality out there...?

This isn't a rebate from Canon, it is a rebate from B&H. As such, they've got to write the cost of the rebate off against their sales so they bundle the camera with a bunch of extras for which they have a high margin and decide to sell much cheaper (possibly at cost?)

1447
Deal like this make me sad and make Canon Australia look like an absolute joke.

Sounds like you missed Canon Australia's 20% off sale back in May:

Pricewatch Deals / Re: B&H $400 rebate scam
« on: July 07, 2013, 04:24:55 AM »
Mail in rebates are effectively you loaning the company you are buying the equipment from the rebate money.

So all of you buying a 6D or 5DIII and looking forward to that $400 extra, well what you've done is said "Here, B&H, you can have $400 of mine for free!"

Mail-in rebates typically have a specific window of time during which you must remember to mail in the barcodes (or whatever) or you don't get your rebate. Then it can take a year or more to receive the rebate.

From the time you pull the trigger until the time you get the rebate, you have effectively loaned B&H $400 for free.

Mail in rebates are a scam and should be avoided like the plague.

They're only a scam if you don't get the rebate, and only a nuisance if you mind having to remove the barcode from the box.  If you would rather pay full price, go ahead.

I'd rather an instant rebate that I don't need to damage my boxes with or that relies on my memory, etc.

I recently got $450 worth of rebates on three Olympus lenses I bought along with my OM-D back in March.  I initially thought they were trying to wriggle out of it when they told me that I had sent the wrong barcode for the camera, but they ended up just accepting my receipt and sent me the full rebate anyway.  It took a couple of months overall, but I paid $450 less than I otherwise would have done. 

You can damn well bet your life they were trying to wriggle out of it. If you no longer had the receipt, your rebate would have vanished down the plug hole.

Had the rebate have been "instant", you wouldn't have had to rely on having the receipt. You also would have had the extra $450 from the moment you purchased the equipment, not some months later.

If you went to the bank and asked them to lend you $450 for a couple of months, interest free, do you think the bank would say "yes"? Hint: if you withdraw cash from your VISA/Mastercard and don't pay it off, it'll earn interest at around 20%. But you, in your infinite wisdom, gave whatever company it was you bought this off $450 free of charge for 2 months.

Quote
I suspect that the only way companies get out of paying such rebates is if the customer, having been lured by the rebate, forgets to mail it in in time or doesn't want to cut out the bar code; presumably enough of them do this for companies to keep doing it.

Right - people get attracted by the "$400 rebate" but then forget to post it, post the wrong details, gets lost in the mail, etc, and the customer never gets the discount that they thought they were going to get. And this ensures that the scammer never has to give out the rebate to every person.

People from others countries are drooling on these deals, and here you are bit**&%^ about these rebates >:(

That would be because I've experience with mail in rebates.

Well at least cid's two pictures are good. Bratislava is quite small and the rest just look like the typical tourist snaps.

EOS Bodies / Re: Canon Dual Pixel Liveview Autofocus
« on: July 02, 2013, 11:49:31 AM »
Or to put it another way, the noise characteristics of the 70D should be about that for a 40MP APS-C sensor using the same sensor technology without the PDAF split.
But then the two parts are combined to one pixel so it isn't it a kind of pixel binning?

That isn't made clear.

Now if it were true then this would impact video photography in interesting ways because to shoot 1/60, that half of the pixel would need to be being sampled at 1/120 - there needs to be time to read the pixel for AF and then let it recharge. So if you were shooting 60fps, all of those pixels would be being exposed at 1/120. Now if you know that's going on then the raw to image processing can take that into account. Why can't the value from the AF read be used for video? Because that's a sample taken before the camera wants to read the sensor for image data to ensure that the lens is correctly adjusted.

For photography it is a different matter - you could pixel bin because the 7fps provides a relatively long pause between times when the pixel/sensor is read.

I'm also hoping that the pixels aren't all split in a left/right horizontal pattern, as the video shows, but that half of them are split vertically, because no one would want the AF system to be sensitive to horizontal contrast only.

Based on what I've read, including a statement from Chuck Westfall who was asked for clarification on the matter, they are all split in the same direction.  That means the Dual Pixel CMOS phase AF system is a giant vertical line sensor, responsive only to horizontally-oriented details.

Any guess as to whether the next generation will have a quad split (2x2) to do both vertical and horizontal or would it be better to use the next neighboring pixel of of the same color instead?

What they might be able to do is to have a pattern on the sensor of PDAF cells rather than just straight up and down.

So maybe the new bayer sensor looks like this:

R.I.G.I
I.G.I.B

I = vertical AF sensor and one for horizontal might look like this:

R.-.G.I.R.-
|.G.|.B.|.G
- = horizontally sensitive AF sensor.

Or they might do:

R.-.G.|.R.-
G.|.B.-.G.|

or

R.-.G.|.R.-
G.-.B.|.G.-

but to subdivide all of the pixels again would really cut into the ability of a pixel to capture light for recording the image with.
