I'd wait if, and only if, the 60D is useless for whatever you're trying to shoot and you're certain the 70D will have the particular feature that you need.

If that doesn't apply, get the 60D.

Well if there's any truth to this... then I wonder if Digic 5 is on the way.

The 1Ds4 and 5d3 would then get the new chip, and perhaps also a 7D2.  2012 could see the chip trickle down to 70D and 700D.  New chip, more video capability, probably an increment in high iso.

In theory then a 7D2 could have the same 18 mpix sensor as the 7D, 60D and 600D.

No, no, no.

The focal length does not change.  Focal length is a piece of physics that's part of the lens design.

Aperture does not change.  Again, this is part of the lens.

Fstop does not change because the previous two items are fixed.  fstop = focal length divided by aperture.

Field-of-view will change because of the crop factor.

Given the same focusing distance, depth-of-field will not change.

Given the same framing, depth-of-field will be greater on the 7D because your focusing distance will be greater (due to the crop factor, you'll have to back up)

I hope that helps.

4" x 6" at Costco or similar.  Dirt cheap, and done on cheap paper with cheap inks.  I don't expect these to last more than 5 years.

8.5"x11" and 13"x19" on my Epson R1800.  Archival quality, but inks are wickedly expensive.  I'm looking into outsourcing.

Photo albums -  I'm very happy with the work they've done.  Looks great and cost effective.

Gallery wraps - I've found a little print shop in my city that does great work at a fair price.  I've only had a few printed up but they're really really nice.

Canon General / Re: Canon 7D noise observations
« on: March 21, 2011, 02:54:25 PM »
Sometimes when we look at review sites that show graphs depicting noise, we are missing a critical element: the quality of the noise.

You've spent some time looking at it.  So have I.

My first DSLR (300D) produced really "clumpy" noise.  These were blobs of chroma noise many pixels (say 10) in diameter that were especially noticeable in shadow areas.  These blobs would really show in prints.  I've found no good way to deal with it in processing.  On top of this was the more random-like pixel-by-pixel luminance noise.

I like the noise of my 7D much better.  At 1600 iso the noise is almost filmgrain-like, and color is still pretty good.  Noise is pretty even between shadow and highlight, which IMO gives it a more slidefilm-like look.  At higher iso you start to see some clumps and the pixel-by-pixel noise goes sky-high.  Still works out better in prints, though.

EOS Bodies / Re: Canon Doesn't Need a Compact Camera System
« on: March 19, 2011, 06:30:13 PM »
IMO the most sensible thing to do would be to have an EF-S compatible system, similar to Sony NEX.

Canon would sell more EF-S lenses, and folks with DSLR bodies might be tempted to pick up a mirror-less body as an addition to the kit.

A mirror-less body coupled with plastic lenses like 18-55 would be pretty compact and light.

Now, Canon, let's please see some light EF-S primes!

... and I think Sigma would do well to spec a 135 mm prime at f/1.8

that would require filter size in the 8xmm size

Wouldn't 75mm suffice ?

Yes.  In practice you'll end up with a 77 mm filter.

Canon's 135/2 has a filter size of 72 mm.  Same as the 200/2.8

Canadian here.  I've never had any issues over the years.

However that doesn't guarantee that you won't have a problem.  To put your mind at ease, you could bring photocopies of your original receipts with you.  Or scan them and put them on the net.  The dates and sales locations will prove your case.

... FF cameras produce better images/video and have more/better glass options.

Actually you have more lens options with crop because crop cameras fit both EF and EF-S. 

As for better images, it depends how large you print.  My largest prints are 13"x19" and crop works well for that.

The EF-S line of lenses are not high on the list of priorities at Canon.
“L” lenses and the development of them are whats needed to get the most out of the 18mp crop sensors.

Hehehe...  Sounds like a line from a full-frame enthusiast and L-snob  Someone who obviously doesn't understand business.  Canon makes good money on their crop gear.  Furthermore, if you want to get the most out of your 18 mpix crop sensor then EF-S lenses like 17-55 and 15-85 are the way to go.  Why struggle with full-frame ultrawides thast have limited focal length range and/or aperture.

This is CR -10, folks.

EOS Bodies / Re: 1Ds Replacement Soon?
« on: March 10, 2011, 07:05:05 PM »
i'm not entirely sure if there's any strategic value in releasing the 1ds4 before the 5d3.

Anyone in the market who would drop 10k on a camera would most likely wait the extra month or two to see what the 5d3 offers.

Em, no.

If a pro needs a camera, he or she will buy it now.  They are not technology-speculating geeks.

A pro will buy the camera for its build, dual card slots, etc.  Stuff that the 5D series doesn't offer.  5D = consumer, 1Ds = pro.  Completely different markets.

Lenses / Re: Lens Recommendation for Weddings.
« on: March 10, 2011, 04:57:18 PM »
Use your 7D.  Buy a Canon 17-55/2.8 IS and an 85/1.8 or 100/2.  These are sharp wide open, focus without hesitation, and focus with great accuracy.  This is all you really need.  I know, because I own the set and I've worked assisting a wedding pro.

Be sure to have backup: another body, standard zoom (maybe the 18-135 that you hate) and a second hotshoe flash.
