Lenses / Re: Lens suggestion - Alternatives to 24-105
« on: March 04, 2012, 08:27:58 AM »
There are a couple but they are not as long that I am aware of - they are the 24-70/2.8 the new 24-70/2.8 Mk.II and the Tamron 24-70 VC. There are also non IS versions of the Tamron and Sigma offerings too.

For the price, value, overall quality and versatility - I will likely be adding a 24-105 to my 5D3 when I bite the bullet.

I started a thread yesterday which is very similar here: http://www.canonrumors.com/forum/index.php/topic,3929.0.html and many have already chimed in with great information - check it out.

I have seen that you cannot mix and match the RF and IR wireless modes. The 600's are compatible with the old 580's via IR wireless only (obviously). I wonder if you can control a 600EX-RT in a soft-box like the Westcott Apollo via the ST-E3 in the hotshoe with RF wireless and have the 600-EX-RT control the legacy 4xx/5xx flash via IR?

Has anyone seen reference to this?

Craigslist.  Face to face in a public location, the buyer gets to test the lens, and you leave with cash.

I have also been successful on FredMiranda too.

When you say "the ISO performance of a FF sensor beats an APS-C sensor by 1.33 stops for an equivalent sensor generation" - the 5D3 is not the same generation as the 40D therefore I would expect well beyond the 1.33 factor - do you agree?

Definitely.

Thanks. That supports the case for a 24-105. It adds $800 to the body price of wither the 5D2 or 5D3. The Tamron also looks very interesting - I look forward to hearing what people say about it oncereleased in the wild - also I didn't get an accurate lock on pricing. One Australian report mentioned $1400 but that may be Aussie dollars.

Anyone know how much the Tammy will be?

It amuses me when people say they don't want to go FF because there's no equivalent to the 17-55mm for FF.  They're correct - the 24-105mm f/4L IS is actually better.  The FF equivalent of the 17-55mm is 27-88mm f/4.5, so the 24-105mm is wider, longer, and faster (in terms of DoF for same framing), and still has IS.  It's true that you lose a stop of shutter speed, but the ISO performance of a FF sensor beats an APS-C sensor by 1.33 stops for an equivalent sensor generation, which more than compensates.  The 5DIII compared to the 40D will be even better.  So, comparing the 24-105/4 on FF to the 17-55/2.8, the only thing you're losing is the activation of the f/2.8 AF points.
Thanks for the insight.

Get the 24-10 Kit, it is a really good match for the 5D series cameras.  I almost bought a second one with my 5D MK III order.  If it does not end up suiting you, you can sell it for over $800.

I am leaning towrds the 24-105 but now also considering the new Tammy 24-70 VC

I've had 5 of the 40d's and loved every one of them.  ISO 800 was pretty much my limit.  Just now, i pulled some of my old ISO 1600 images into LR 4, and they really look good, so newer processing has changed things.

With the 5D MK II, I was limited at ISO 3200 originally, but with the better image editors, I can now use ISO 6400 in a pinch without too much noise.  I expect to use ISO 12,800 or even 25,600 on the 5D MK III.  Thats a really huge jump over my beloved 40D's.

Here is a theatre shot at ISO 6400 taken recently with my 5D MK II, I'm really enthused about the possibility of two more stops.  I would have bought it for one more stop.

5D MK II, ISO 6400 135mmL at f/2



Nice shot for ISO6400 - great example of the capabilities of the 5D2 and 135L. Thanks!

First off why are you doing the upgrade? Why do you need a different body?
I love the 85 and the 135L I own and hope to use them more. I have also shot 5Dc and 5D2's and love the images they produce.

In terms of cleaness, likely ISO 4300 on the 5D3. The 40D at ISO 800 would be as clean as the 5DII at ISO 2133 (this has been tested in lab conditions)
I imagined it would be better - thanks for confirming it.

I would get the upcoming Tamron 24-70mmm f/2.8 VC lens. That's the best of both worlds, image stabilization, and f/2.8. It's also reported to be very sharp.
The new Tamron does indeed seem intriguing - any word on when it will be available?

The 24-105mm f/4.0 IS would look cleaner on the 5D3 than the 17-55mm f/2.8 on the 40D, if the DOF is the same. However they would be about equal with the 5D2, with only a slight improvement.
So, it would appear that the 24-105 kit lens would be a great addition to a new 5D2 or 5D3. Thanks for your insight.

If one opted to purchase two 600-RF's and not get the ST-E3, would they get all the functionality in a 600-RF as they would a ST-E3? I would imagine the 600-RF would be of benefit to add fill in many situations rather than the ST-E3.

ISO Question:
I've never owned a 40d but I'm comfortable using 2000 iso for any of my clients. I've used 3200 and even 4000 before but personally I don't like pumping it higher if it's for work. For personal use I've done even higher! Judging from the examples and from a non pixel peeper point of view (What matters is if it's good enough for the clients right?) I'd go as far as 25600 on the 5d3!

Lens Question:
Yes it'll more than make up for the stop. I love the 24-105 and know a couple of working photographers who use that lens as their main money maker. The question would be more if you get the 24-70 is that the only lens that you will get for awhile? at 70 on a fullframe you really don't get that much reach.

You can't go wrong with either though

Thanks for the insight - I assume you are shooting a 5D2?

For reach, I also have the 85/1.8, 135L and a 70-200/F4/IS. I am heavily leaning towards the 24-105.

EOS Bodies / 40D vs 5D3: ISO and lens question
« on: March 03, 2012, 06:37:54 PM »
I currently have a 40D with a 17-55. I am looking at getting a 5D3 with the kit 24-105 lens. I am also knocking around the notion of getting the 24-70 II instead of the 24-105 in order to maintain 2.8 aperture.

I am a hobbyist who likes to do portraiture, the odd event, vacations and the like. I also have an 85/1.8, 135L and 70-200/4/IS.

ISO question:
I never go above ISO 800 (unless I really need to) on the 40D - what would be an equivalent ISO on a 5D3 or even a 5D2 for that matter? 3200?

Lens question:
The 17-55 is on the camera 95% of the time. Based on the better ISO performance of the 5D2 or 3, if I boosted the ISO up to make up for the loss of a stop on the lens, do you think they would balance each other out from a noise standpoint (DoF issues aside). In other words, if money was not an issue, as a general everyday lens, if you were me would you get the 24-105 or the 24-70 II?

Thanks in advance!

Rob Galbraith tests new camera and comes up with empirical numbers for most popular camera models. I am sure the raft of recent announcements will show up on his list shortly such as the 5D3. 1DX, D800, D4.

The only time I have seen issues with buying something faster than the device (or user for that matter) would be putting racing skies on an amateur skier  ;D

EOS Bodies / Re: Best cards for 5D Mark III? SD & CF
« on: March 03, 2012, 08:02:45 AM »
Rob Galbraith has always been a good resource for CF/SD card speeds as they relate to cameras, although there is no recommended cards yet for the 5D3:

We are faced with similar pricing practices here in Canada (most of the time). The %d3 has launched here at $3799 when our dollar is equal to a U$D.

3.5K is a little steep for this rig - I would have like to see integrated wireless flash control to justify the extra $$$.
