Lenses / Re: Canon EF 100-400 f/4-5.6L IS Patent Pending

I suppose another way to look at this is that a 100-400 mk2 isn't just around the corner.  It's still early in its development phase.

What's your budget?

Have a look at Sigma 120-300/2.8 OS.  Not a light lens, though.

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.
