Yes, the contacts that deliver power for AF also deliver power for IS.

FWIW, the fastest and easiest way I've figured out to set AFMA is just set up on tripod, set aperture wide open then take a picture of a window screen at about a 45 degrees horizontal off perpendicular. Zoom the shot on the camera LCD all the way and verify where the vertical "focused strip" of screen is in relation to zooming the center of the shot. Adjust AFMA to get the "focused strip" in the center. I'll itterate between focusing from further out and focusing from closer in and then "average" the results to settle on the AFMA setting used. I have found this to be very accurate and quick...the texture and color of the screen really shows the focus zone prominently and the faster the lens the better it shows. LOL, maybe I'll get torched for offering such an unscientific and gadget free approach, but the shots afterwards pass the pixel peeping tests.

Do not use AI Servo in low light
It has little to do with the lens. Its very difficult for a camera to find focus in low light and takes a second or two. No way can it AF continuously in very low light.
Just use one shot and center point if the light is very low.

B + W filters. They are superior to Canon.

I just returned from an meeting of our local photoclub and I am a little bit dissatisfied.
Three members bought an 6D and we compared the pics. And they are really different. They took the same lens to shoot equal macro photos. The IQ is visible different. One cam had obiously more noise >400, the other one´s IQ was visibly more flat (color and contrast).
The owners of the 6D will tra to send it to Canon to optimize the IQ.

In my eyes it ist dissatisfying, if you spend 2000€ and a lot of time in choosing the "right" camera. And then it is just fortune if you get an goog model or not.
Sorry, but I had to say this.

It is very unlikely that the cameras are at fault for the difference. I'm quite happy with mine.

As to whether Canon deliberately made it a lesser camera than they could have, yes and no: They naturally made it to a specific cost, that would allow them to manufacture and sell it with a healthy margin, in a way that doesn't hurt the sale of the 5D III too much. Shaving a third off the cost of the 5D III means a lot of cost cutting. The only compromise I disagree with is the smaller screen, it looks like they could have fitted the 3.2" unit. If dropping the GPS could have paid for that, they should have. But they clearly see it as the enthusiast traveller's camera, and as such it does make perfect sense.

Thanks everyone for your helpful responses. I think I may go with the Phottix Strato II.

Another really happy user of 5d mkII. I 've got it since '08, and plan to have it till its dead. But if I was to buy now a new camera it would be mkIII, if I could afford it, of course.

The new Sigmas promise better QC but the optical formula of the 17-70mm is, as far as I know, unchanged. So, what you'll be getting should be something akin to a golden sample of the previous version.

The 30mm f/1.4 and 17-70mm lenses have different uses and advantages so a comparison doesn't mean much. Just be aware that the zoom won't match the low-light ability or thin depth of field of the 30mm. If, as you say, you've got a good copy of the 30mm, I'd recommend you hang on to it if you possibly can.

The part I think is neat is that the video could be shot using either dx or fx format. That type of functionality would be great if canon could use its software to control the sensor size to either be FF or aps-c on an actual FF sensor. That would allow beginners a smooth transition to a FF camera while allowing them usage of any existing lens that they have. I'm sure there would have to be trade offs such as 24mp FF or when using apsc mode it would be 12 or 15 mp. Even better would be for the camera software to recognize the lens and switch automatically so that there aren't any mistakes when photographing.

This could open up a ton of demand. Further thinking, this would allow canon to reduce the number of sensors that they have to make. People love to hack. Could you imagine if canon put these sensors in the rebel line but locked them down to apsc size? You would develop huge community of people that would learn how to jail break their camera just like an iPhone to get the FF capability. It wouldn't matter to canon because the cost of the sensor has already been taken in account with the initial sale of the camera, but the camera would still be limited by the af/IQ of the rebels. Prosumers and pros would still buy the higher end cameras and canon would be in a better position to sell glass which is where it makes most of its money anyway. People like to tinker with things like that, just look at majic lantern. If you jail break your camera, you would still need to buy ef lenses to use the sensor size.....

Have owned a 60D since December 2011, first DSLR. Have become addicted. Want a second body now to have a different lens available at some shoots, but also for taking on camp outs where I am worried about ruining the 60D. Thinking that T3i is the best choice because the body alone is so cheap and still get a similar IQ to the T4i and the 60D. What is your vote?

If you are worried about destroying or damaging your camera while camping, have you considered a pelican case? It is a hard shell case, waterproof, customizable foam padding, etc. I have been using them for years canoeing and they have saved my gear on more than one occasion. We use them at work.... I stood in disbelief as $200,000 of electronics slid off the deck of a frigate and splashed into the Atlantic, then it bobbed to the surface.... We hauled it aboard and it was dry and worked!

Thanks everybody for the replies.I think I'm going to wait till I'm clear on contrast, color rendering and flare control capability of the 2.I just don't want to regret my purchase later,which ever lens I buy,I'm low on funds and in the cost of IS I can easily get a 17-40 so I hope u can understand my dilemma

Thanks in advance

Thanks guys for the helpful posts.

TexPhoto, I've used the 300 IS I before, loved the IQ but its a bit of a beast. The sigma looks a lot more compact, would you agree?

The 17-55 is much better than the 17-40, but its also more expensive. If you want to go to FF, get a 6D and a 24-105mmL. A big step up IMHO.

Click to expand...

I think that is outside of his price range. If he gets a GREAT deal on the 6d and 24-105 for 2400, I don't think he has the set aside funds for it as described (even if he sold all of his stuff). These are best case scenarios... $500 for the t3i and 18-55 if he's lucky, 100 for the 50mm f/1.8, 300 for the 50mm f/1.4, 170 for the 55-250, and let's say 700 he was going to spend on the 17-40. That totals to 1770... so he's still 600+ away.

Thanks for the replies every one. I got the EF 16-35 f2.8L II before the rebate expired. I am guessing it will serve my needs just fine.

I just don't get the title of the thread.... Canon comes out and says that a 7D2 is coming this year and that it will be revolutionary..... someone please explain to me how that gets translated to "Future of Semi-Pro DSLR is FF"

"MM: Yes, they would be correct. For us, it’s about looking at what the camera has the potential to be and then adding that to what it can currently do. I do think the current model is still very attractive to buyers. And while we are, of course, developing its successor, it’ll be one that incorporates a certain number of innovative technologies. We will not be putting out a product with merely better specs, but one that has evolved into new territory. But then again, we’re not talking about something a long time from now either."

There have been two interviews in January with Mr Maeda, Canon's camera boss.

In the fist one he confirmed the 7DII. That's the one that you've quoted.
In the second one, from DPreview, Mr Maeda is quoted saying:

• MM: From our semi-pro users there's still demand for APS-C but in the future, I think we will see an increase in the number of full-frame models.

I think it's a given that both the 70D and the 7DII will be announced this year.
The future that Mr. Maeda is talking about is at least three-four years from now.

This is why I like this forum.... I notice something strange... ask a question, and the answer(s) are given. Thanks all!

Dustin, much grattitude for your detailed and quick response! My goal is certainly not to make a living from landscape and wildlife...more like to try to eek out a similar percentage that you are doing.

Are you familiar with Marc Adamus? One of his shots got me re-inspired for photography. Not sure how big of a deal he is now.

Indeed, landscape is very fulfilling. In my younger days, I fancied myself an artist and wanted to design cars. I sent my idea to its intended target, a manufacturer in Germany. Three months later, they returned it with some legal forms which I never signed. The copy of my design had been folded up and worked over a lot. Alas, it was not a realstic goal for me. Not enough people get to do it. I also, always felt drained after drawing or painting something. I never feel that way when shooting photographs that I love...or even of editing them (after a few hours at a time it gets old, of course.) If it's photo work that I don't love, then I definitely dislike spending time with it, but sometimes that has to be done.

But it was strange back in art school, that all of my classmates felt doing their work was therapeutic. It never was for me.

I also like to write, but too many people seem to be doing that these days, too. Every form of creativity is highly subjective, did you know that?

There is a lot of 'what do you think I should buy' topics, and grouping them together would be really nice. Toss on top of that doing a sticky FAQ on what needs to be a part of these recommendation requests. Things that are constantly asked - what do you have, what do you shoot, what's your budget - those tidbits. Lens discussions shouldn't be mixed into rumors.

Thoughts?

Don't mean to bump an old thread here - it seemed to be the only one where pixel knight users were gathered

I have the TR-332TX and rx, but there isn't any 5d mode when I go into the settings. Are they on the wrong firmware?

i think it's a Sharpest in canon 70-200 (except 2.8 IS II i haven't use it)
about update soon. i don't think so

If budget is not an issue, the new 24-70 II is the way to go. On my copy, Reikan FoCal showed the sharpness at f2.8 is 985. Not many zoom lenses out there have this kind of sharpness at f2.8.

My comment is based on real life shooting.....let me know if you want to see some photos with 5D III.

Many owners of 24-105 claimed their copy is razor sharp, but the Canon MTF chart doesn't indicate that at all. Again...I owned 2 copies of 24-105 in the past and I didn't see that. I ended up shooting alot with 50mm f1.4 @ f1.8 to 2.8.

I have a good copy of the 24-105 but for what i use this lens for I'm usually shooting it at f8 so its sharp

A really nice wider option I have also picked up is one of these
voigtlander 20mm it has les distortion than the 16-35 which is one of my favourite lenses
but i carry the 20mm voigt and the 40mm pancake pretty much everywhere and my 85mm for portraits

Be able to get sharp picture at f2.8- WIDE OPEN - is priceless. I just don't see myslef shooting f8 in lower light, even on FF.

Why not buy a 40D for $280 to $350 ? (available on the Craigslist)

I sold mine with flash not popping up for $250 last year. The guy who bought it from me is re-selling it for $220 after playing with it for six months. Updated actuation is around 14,000.

This is why I don't bother with most 3rd party lenses except Zeiss lenses.

While I'm in favour of IS, I've just read from another poster that IS can affect bokeh

http://www.canonrumors.com/forum/index.php?topic=12818.msg230053#msg230053

while I've put a parallel question in the relevant post but it seemed right to put the question here also - is this correct?

Click to expand...

If the IS elements are so decentered at the moment of the shot, to affect the bokeh, this means that without IS, you whole shot would be bokeh only. Not to mention that you can always turn the IS off.

On the other hand, the IS poses design restrictions, and they might affect the bokeh.

The biggest reason I was surprised by this statement is because I've heard most people say that they never turn it off ... Sounds odd if there is a possibility that your IQ can be compromised

Re: IS sound probleme 100 2.8 L IS USM Macro with my EOS 5D MK III ?

Hello,

for your information....

CANON has now exchanged the IS System, .... and now all is fine and quiet.

Thanks to CANON !!,
Thank CR Forum for your help !!
