EOS Bodies / Re: A New Entry Level Full Frame Camera? [CR1]
« on: September 18, 2011, 03:11:41 PM »
A 5d2 sensor in a Rebel body: plastic + pentamirror.

Sounds like an awesome travel + hiking camera where every gram counts.  I'd definitely buy it.  But I doubt that this is gonna happen any time soon.

EOS Bodies / Re: APS-C Camera with an L Lens as a Kit

There are a few 60D plus 15-85 kits out there, if you shop around a little.  You may be able to save some dough.

e.g. here in my city

Then how do you know if you're going to stick to full-frame?  Maybe full-frame won't be good enough for you at some point in the future, and maybe you'll upgrade to medium format someday.  Shouldn't you be buying medium format lenses, to be used with adapters, just in case?

I'm just playing devil's advocate here.  The point is, buying a lens is not like marriage, forever till death do us part.  Lenses can be sold just as easily as they are bought.

15-85 is apsc-only because it can't project a 15 mm ultrawide image on a full-frame sensor.  Restricting the imaging circle has its design advantages, and makes a high-performance 6x zoom possible.

I suggest deciding on a format now and sticking with it.  Either get 5D2 plus 24-105, or 7D plus 15-85.

United States / Re: Why a shutter curtain?
« on: September 08, 2011, 03:59:47 PM »
I think originally it was meant to prevent sensor blooming in bright light.  I'm not sure if this is still an issue today.

Another advantage of a shutterless camera: flash sych speed = max "shutter" (acquisition) speed.  i.e. 1/4000 or 1/8000

EOS Bodies / Re: Advice on purchasing a new APS-C body
« on: September 08, 2011, 12:00:21 PM »
From a logical perspective I agree with AG.  Get the 600D plus 18-55 plus 55-250.
This'll net you the LCD screen, image quality, etc.

The 7D is all about fast AF and fast burst speed.  Doesn't seem that this is your first priority.

From a diplomatic perspective, consider a second 60D.  Then both of you will have the same camera and one isn't better than the other...

Canon General / Re: Canon 5dmii quirk or software issue?
« on: September 07, 2011, 03:57:44 PM »
I use a CF card reader that plugs into a USB port.
Insert the card into the reader, create a directory, drag and drop the files.
Convert CR2 files to DNG (optional)
launch Bridge and select your newly created directory.

Lenses / Re: wide angle lens
« on: September 06, 2011, 06:25:51 PM »
Which one can capture the most of the area without getting any significant distortions (fisheye type)?


Try Sigma 12-24 mk2.  It's not particularly fast, though.  But 12 mm is crazy wide.

If you want speed there's Canon 24/1.4

Which one is the best?  There's no answer to that.  Canon 16-35/2.8 is a good compromise between wideness, speed, focal length range, and image quality.

EOS Bodies / Re: Having Multiple Camera Systems
« on: September 06, 2011, 05:22:54 PM »
I agree with cornershot.

How about: 600D
17-55/2.8 IS
85/1.8 or 100/2

I've shot weddings, family gatherings, and gone traveling for months on end with a similar setup.  It's very versatile and will net you great image quality.  I'd add 55-250/4-5.6 IS for general outdoor telephoto shooting.

If the 17-55/2.8 IS is too big and heavy then consider Tamron 17-50/2.8 non-VC.  Deadly sharp, small, under-the-radar lens that delivers again and again.

I'd like to see a built-in espresso maker.

To fill that lens mug, of course!

Lenses / Re: Lens for a big sun in the pictures
« on: August 21, 2011, 11:24:26 AM »
Actually, the moon and the sun are two subjects that are great for mirror lenses.  They don't move very fast (manual focus, live-view), they're bright, and you won't see any bad bokeh.

As for 300/4, sure, that would be nice.  But it's an expensive lens, and you won't need aperture; you'll be stopping down!  So 70-300/4-5.6 gets you the same thing.  That said, you could mount a 1.4x TC on a 300/4.


That may be true, but not for $119.00 price, and 500-800 mm focal range. When you go in to some really large focal lengths, size and amount of heavy glass simply makes physically impossible to build classic telescopes.

This is a shot taken with the basic Meade ETX125 mirror lens which is 1900mm and f15, taken of the flimsy tracking mechanism and mounted on old and pretty heavy Benbo tripod. The moon do not fit in the frame so this is composite of two shots, at manual exposure of 1/500s, some adjustments for sharpness and noise reduction.
Nice photo.

I'm not saying that mirror lenses are the best tool for photographing the moon.
I'm saying that the moon is one of the best subjects for a mirror lens.

Here's some stuff on mirror lenses:

I wonder when Samyang is going to produce a fast fifty.

Lenses / Re: Why not EF-s "L" lenses?
« on: August 02, 2011, 05:11:56 PM »
Forget about Sigma.  Nikkor 35/1.8 DX with AF-S autofocus is the competition that Canon will answer to.  The Nikkor is a really nice lens.  Hopefully Canon will match it, and hopefully they'll do it sooner rather than later.

Lenses / Re: why????
« on: July 25, 2011, 04:03:53 PM »
I agree with you, Unfocused, that APSC isn't going away.  It's the new 35 mm.  Quality is good enough for most folks including myself.

I'm generally a defender of Canon, but I am really having some doubts about their lens division. I'm just not sure it shares the same vision as the rest of the SLR unit. Seriously, look at the lenses they've chosen to introduce over the past few years: updates of massive supertelephotos that fill a tiny niche market, a nice quality 70-300 mm L zoom that the jury is still out on whether there is any market for it; a specialty fisheye zoom that also fits a narrow niche audience and which they can't even seem to bring to market anyway.

In the meantime the SLR division brought out the 7D and 60D, two higher-end APS-C bodies, and aside from the 15-85 mm zoom, there have been no corresponding lenses released.

Imagine the sales jump they'd have if they introduced an EF-S 100-400mm f4? Lighter, faster and about the same price as the current full frame 100-400. Sports and wildlife photographers would be lining up to buy that lens and 7D combination. (Now before all the nitpickers start picking away, this is only an example of the creative options that the lens division could be following if they were to get with the EF-S program like their SLR brethren have gotten with the crop sensor program.)

I have to wonder if the lens division needs more forward-thinking management.

Well they did put out a few consumer zooms like 18-135 and 18-200.  Yawn.  The 60/2.8 macro is pretty nice though.  Goes to show that Canon aren't opposed in principle to EF-S primes.

Still sorely missing is a cheapo 30/1.8  Hello, paging Canon?  Must counter Nikon on this??

17-55/2.8 IS is a nice lens but it's hideously overpriced.  It should be around 700 bucks.  I'm thinking about selling mine.

Now that Tokina and Sigma have discontinued their 55-135/2.8 and 55-150/2.8 respectively (OS version on the way supposedly) there's a gaping hole out there for a quality 55-something portrait zoom lens.  IMO an EF-S 55-135/2.8 IS is sorely needed.  And this lens shouldn't cost more than 1200 bucks.

FWIW, 100-400/4 would have a 100 mm front element regardless of its imaging circle.  Huge size+price jump.  Sigma's new 120-300/2.8 OS has more than a few folks salivating though.  Now there's a sports+nature lens.
