Lenses / San Francisco camera store recommendation
« on: April 15, 2014, 02:08:43 PM »

I'm visiting SF this week and I'd like to know if anyone can recommend me a good camera store, like B&H or Adorama in NYC. In particular, I'm interested in buying the Rokinon 14mm 2.8 at a good price.

Thank you!

In theory about half, since the sensor would be mounted on an axis through the middle of the sensor. Unlike the mirror that needs to move forward as much as the sensor is high. Pivoting would need half the distance.

Man, I'm sorry. No offenses, but your idea is just plain dumb.

A short flange allows you to make the lenses about 2 centimeters shorter.... This is a huge difference in tiny kit lenses, but as you move up to bigger and better lenses it makes far less of a difference.

The short flange also means that light is now entering at greater angles and that becomes problematic for the sensor.... basically, light has to shine into little pockets or indentations on the sensor, and if it is at too much of an angle shadowing will occur. Also, bending the light more sharply in the lens increases problems with chromatic aberrations and increases reflection problems. This is why the "big whites" are so long.... avoid sharp bends... You could easily make them shorter, but image quality will suffer badly...

A lens designer can always increase the flange distance at will by extending the rear end of the lens barrel. Think a lens with a fixed, built-in extension tube. That is exactly what Samyang did with the 5 lenses they released for the Sony FF MLC E-mount. Their Sony MLC lenses have exactly the same flange distance as their Canon and Nikon DSLR counterparts:

You're bound to run into confusion when you have (a) too many cameras simultaneously on the market, (b) when you release cameras too rapidly. The EOS 100D came out in 2013 ... it's an "entry-level" camera, so the EOS 150D should be here this year, as well as the 750D ... what happens in 2017 (the new 300D) and 2019 (the new 100D or 1000D or 000D)? Plus, eventually the 5D and the 1D series will reach Mark L and even more eventually Mark C level. But before then, there'll be the Mark XXXVIII and, fitting for the 1D series, the Mark XL.

You forgot about the 100D/SL1. What will happen to  the x0D line after the 80D and 90D?

Canon General / Is the x0D line doomed? (Canon naming scheme)
« on: January 17, 2014, 11:53:25 AM »

One thing I never quite understood is why Canon has different naming schemes for its entry-level product line across North America, Europe, and Japan.

I mean, the whole "the smaller the number, the better the camera" as a whole is awesome, so why ruin it and replace it in North America with T2i, XSi, SL1, T3? Isn't 600D, 100D, 1000D much better?

Well, you may be tempted to answer that the reason is historic, that Canon already had the Rebel brand well-stablished here. But that only pushes the question backward: why did they name it Rebel back in the film days to start with?

Which begs the question: now that we have a 100D camera, what will be of the x0D line after the 80D and 90D are released in a couple of years? Makes me wonder if they are going to bring the Elan brand back.

Lenses / 135L or 100 Macro IS?
« on: January 17, 2014, 11:43:46 AM »

I think I may soon have a couple hundred bucks to spare on a shinny new lens. I'm wondering if I should get the 135L or the 100 Macro IS. They cost the same here in Canada. What would you recommend? I'm an amateur, not a professional, and I just want to have fun taking beautiful pictures. My current equipment is listed below.

Lenses / Re: New Samyang 10mm f/2.8 ultrawide! Looks impressive...

Am I imagining things, or does that photo of the Bower you linked to have '14mm 1:2.8 ED AS IF UMC' written on it, exactly as the other two have?

Forget the photo, look at the specs:

They are different in Angle of View, Minimum Focus Distance, and Groups/Elements.

Besides it, the Bower says "Optimized for APS-C Size Sensors", while the others say "Compatible w/ Full Frame & APS-C Cameras". Yes, I agree that the wording is a little ambiguous, but the Bower not mentioning full-frame is indicative of a diference.

I bought the 14mm after reading the hype and it was awful.  Users also said it was EF, but it came with a note in the instructions stating that it was optimized for crop cameras and FF users should expect poorer quality.  That was a understatement.

You might have bought the wrong lens. There is the Bower 14mm, which is for APS-C (albeit with an EF mount), and then there are the Rokinon/Samyang 14mm IF ED UMC. They have different specs.

Why do you feel screwed? How does their decision affect you?

Did you buy an EOS-M? Didn't Canon deliver it? Doesn't the camera do what they advertised it would do? Isn't your camera going to keep working as it always have, EOS-M2 existing or not?

So would you care to explain what Canon could possibly have done to screw you? Because all I see is that you paid for and have in your hands a working product that performs just as well as it always have. So, please, stop whining like a spoiled kid and go take some nice pictures with the camera you have.

Why would you sell a camera that you know is about to stop working? I don't think it is fair to the buyer. Ethics matters.

Google Translate is pretty opaque with the wording about the AF system...

The video makes it pretty clear that it uses Hybrid CMOS AF II (from 100D/SL1). No DPAF from 70D.

Hybrid CMOS II ≠ DPAF.  The sensor described above is the one in the 700D/T5i and 100D/SL1 (which is different than the T4i/650D and EOS M sensor - those have the original Hybrid CMOS which is basically only the center of the frame, whereas Hybrid CMOS II covers a much larger area of the frame).

The 700D doesn't have Hybrid CMOS AF II, it uses the exact same sensor as the 650D. Other than cosmetic differences and the kit lens, the cameras are identical.

why should canon produce a new 18 MP sensor with dual pixel AF when they have already such a 20 MP sensor?  makes not much sense.

and when that is wrong... then i guess the whole rumor is not much but hot air...


or wait.. i got this wrong i guess.  ???

they say they will put the same old 650D sensor in it?
not dual pixel... but hybrid cmos?

Not the 650D/700d sensor, but the 100D (SL1) one.
