But clearly I am in a minority as these ad companies would not invest in such technology unless they got back a good return.  So some people (probably many people) are using these pop up type ads to order stuff.
I think you'd be surprised. The guy that invented pop-up ads wrote an article a month back...the effectiveness of pop-up ads is laughably minor. Click through rates in the hundredths of a percent, etc

Finally including the intervalometer makes me laugh. ML has had that one solved for years...good thing they finally figured it out themselves

EOS Bodies - For Stills / Re: Guessing Game- Canon or Nikon?

Here's another one:  Nikon or Canon??
My guess is Nikon on this one. Partly cloudy day, yet you've got a lot of detail in the lifted shadows. The color on the trees also doesnt feel like the green from my Canons, though that could be processing.

If it's Canon, then I'd bet you blended exposures

Third Party Manufacturers / Re: And what does Canon do?
« on: September 04, 2014, 11:14:51 PM »
Well, the Scarlet Dragon is what, $20k, and that's assuming you are only doing studio shoots with lots of free time to use one battery and one RedMag. By the time you get the batteries, the storage, the processing power, and the rig, you are easily over $30k for those features you mention.

And then of course, you're relying on manual focus if you really want accuracy...which kind of negates the advantage that 100fps gains you (do you really want to manual focus your sports/wildlife shoots?).

I'm more impressed with Blackmagic, who can give you 30fps (more than enough) at 8MP for 1/10th the price.

LOL. I find it interesting that you automatically think it would be crap. I don't necessarily think the Sony CAMERA that included this sensor would be great...and I do think that Sony has thrown out too many products lately for all of them to stick. However, on the sensor front...I think a 50mp FF sensor with high DR would be awesome.
Not to mention, if Sony had the hackers Canon does with Magic Lantern, a 50MP sensor with their DR means you could have a video camera that is nearly capable of the resolution and DR of the Red Dragon sensor. Hell, even managing to hack 4K out of that camera would be a big step forward

As I said on the first page, Sony introducing a new camera wouldnt surprise me. They've released as many cameras as lenses in the last 4 years for E-Mount. I'd be more surprised if they said they were releasing 5 lenses instead.

Proof, please.

http://www.lensrentals.com/blog/2012/03/d-resolution-tests

D800 is capable, with the very best lenses, of bringing more resolution to an image. But, it is only with the best (1050+ lines average) lenses that it makes the difference between a 36MP and 22MP.

And that is of course working off a tripod in lab perfect conditions. In more practical conditions (especially handheld), you'd see even less gain with anything but the best lenses. Basically, if you want the most of the D810/D800E, you want the Zeiss lenses.

Of course, this isnt a knock against a 36MP sensor. Its capable of more in some circumstances, and in every other one, its on par with a smaller sensor. But, if you're considering a 50MP sensor (and the hassles that come with that), its good to know what you are actually gaining

.
Doesn't Sony introduce a new camera every day?
18 e-mount cameras since 2010 (not counting video cameras)....23 e-mount lenses (of which at least 2 were refreshes of existing ones).

Imagine how much better off they'd be if they had just made the NEX5 or NEX7 and build a lens system around it.

EOS Bodies / Re: A Rundown of Canon at Photokina

Basically the new 7DII/X not so attractive, just a "turbo" version of 70D...
Think i should get ready for FF like 6D or 5DIII if when 7DII/X announced, hope the FF will drop...
That's all the original 7D was, just a "turbo" version of the 60D (or rather, the 60D was a toned down 7D). Both those cameras sold incredibly well.

EF 24-105mm f/3.5-5.6 IS STM
I'm guessing this means the 24-105L is at the end of the line? Or will they have 3 lenses, this (replacing the 28-135), the 24-105L, and the 24-70f/4L?

I wonder if the anti-flicker thing is a video or stills technology.  If it's video then, meh.  If it's meant for stills to help handle low frequency florescents then that's a bit of a game changer for indoor sports.
I'd bet its a video feature. The 7D gets used a lot in sports production, so the 60fps and flicker removal would make a lot of sense.
A bit confused by the 24mm f/2.8 EF-S pancake prime. I use the 24mm f/2.8 IS on my SL1 and it is tiny.
I think its partially size, but also price: http://camerasize.com/compact/#448.345,448.288,ha,t

Size isnt a big difference, but I cant see the pancake costing more than $250, and I'd bet it retails the same as the 40mm pancake.  I could buy both pancakes AND a 50mm f/1,8 and still have money leftover instead of buying the 28mm IS.

Lenses / Re: Canon Price Drops on L Lenses
« on: September 02, 2014, 02:15:16 PM »
As for your CIPA comparison of 1H14 to 1H13 – keep in mind that the major players in mirrorless have all released new models this year, whereas the #1 dSLR maker has not released a new consumer model so far 2014.  I think you're making too much of a short-term trend.
Yep, no new xxxD, xxD, or xD camera from Canon would certainly affect short term sales, probably in the same way the T5i, 70D, and 6D (actually being available closer to Dec 2012) coming out in 2013 boosted that years sales for Canon. What were the ratios in 2012 and 2011? Not to mention, ratios that are 3:1, 4:1, etc are still pretty massive...you're talking several years at your presumed shrinking pace til they'd be 1:1

edit: Yeah, so, the 3 year trend line pretty much shows mirrorless as a steady niche, and DSLR sales heavily dependent on new cameras coming out (notice the sharp drop after Photokina announced cameras have been sold a few months). When Canon and Nikon both release entire new lines of cameras (2012 and 2013), sales are seasonal but steady. When they dont, they slump.

Id also say there is a clearly slight decline in DSLR sales as a total trend, but its hard to attribute that to mirror less. Could be the lack of big improvements in DSLRs...could be world economies...could be distribution delays carrying over from 2012

EOS Bodies / Re: Pricing for the 7D Replacement
« on: August 28, 2014, 04:10:24 PM »
I hope it falls inside the $1700-1900 bracket but it will depend on the final specs. The original 7D was selling at launching around $1,600
Yeah, not to mention the 70D came out ($1199) at about the same price as the 60D ($1099) when it launched, so, I dont think you'll see a wild swing in the price on the new 7D. The original launched at $1699, I'd bet somewhere between that and $1999 is your price target.

Especially since there has been no specific rumored spec that makes me think its some crazy departure from the line.

EOS Bodies / Re: F8 AUTOFOCUS
« on: August 26, 2014, 06:35:36 PM »
I'm still confused. Are you saying that my lens would autofocus at f5.6 or f6.3 but not at f8 or f11 and that I should be using manual focus at any aperture smaller than f5.6?
No, in this case, its referring to the maximum aperture a lens has. For example, a 100-400 has a max aperture of f/5.6 at 400mm, and so it will auto-focus on all Canon cameras. If you stop it down to f/8 or f/11, it will still autofocus. However, if you put a 1.4x converter on it, you've turned it into a 560mm f/8 lens, and it will no longer autofocus on most Canon bodies (1D series and 5dIII aside). The autofocus system relies on light and contrast to focus, and you've made it too dark a lens for the auto-focus system to work reliably.

Now, technically, it will auto-focus at f/8 or f/11, but, odds are whatever you are shooting has moved on in the 5+ seconds it took to lock focus. And in some cases, it wont lock focus at all.

So, gaining f/8 auto-focus is more about the ability to use teleconverters on lenses that are already a little slow. A 2x on a lens that ends at f/4 or a 1.4x on a lens that ends at f/5.6. Generally its important for wildlife shooters, which is why it makes sense that a 7DII might have it (and say, a T5i wouldn't)

EOS-M / Re: Finally a 50mm for EOS-M...
« on: August 25, 2014, 04:40:16 PM »
Yep, the EF-M version is actually one of the heaviest models they make for this lens, so, its definitely an adapter built in.

Obviously for Canon EF, the 50mm from Canon is cheaper and has auto-focus. And there are endless 50mm options for mirrorless cameras that make it silly to get this for those, unless it somehow has world-stopping sharpness or bokeh.

They pretty much are making cine lenses for people that want a set with focus grips. Makes sense, especially since the other cine options are 10x the price.

Lenses / Re: A New Pancake Lens? [CR1]
« on: August 25, 2014, 12:52:21 PM »
Can somebody explain the appeal to me? Not trying to start a flame war, just trying to understand.
I dont think they are intended to compete with the other primes...rather to serve a complementary purposed to larger kits.

For example, I have an 11-16mm, a 17-70mm, and a 55-250...all lenses I like and that aren't "heavy" per say. I had a 200mm f/2.8 as well at one point. I'd take them backpacking, I'd take them in my boat kayaking, etc. On longer trips, the extra 4-5lbs of those lenses adds up quickly. It weighs me down and takes energy away, making me less excited to do photography. It affects the performance of my boat and takes up a lot of space.

Now, make that just a 24mm and 60+mm pancake (especially combined with an SL1 or TXi camera), and suddenly my total kit weights about <2lbs, instead of say 7-8lbs. I can take it in a smaller dry box, which also means less weight. There's also physical limitations to those boxes...I might need a pancake to even fit it in a box that works for me.

Mostly, just compare a 60D w 35mm f/2 IS vs an SL1 with 40mm f/2.8. It's a BIG difference in size: http://camerasize.com/compact/#100.368,448.345,ha,t

And the tradeoffs are relatively small. No swivel screen, lower fps, less weather sealing, etc. But, for people that need portability, those tradeoffs are often much better than going mirrorless if you still do sports shooting.
