EOS Bodies - For Stills / Re: 1D X won't wake from sleep
« on: August 21, 2012, 09:24:06 AM »
You are actually expecting too much. We are not living in a world, where companies invest insane amounts of money into testing their products, before they eventually get to market. It took Canon long enough as it is.
Think about development procedures.

Canon definitely tested many lenses and lens plus extender combinations with the 1D-X. We know this from the autofocus documentation.

If you have to go through something like that in Q&A you will not likely spend a lot of time for each combination, trying to get through the procedure within good time. Will your test camera body go to sleep during such tests? I dare say it will not. Otherwise, managers may be less then happy with the work performance of those testing the combinations.

I propose a simple workaround: Configure the camera to fall asleep later. Apart from that you can still get the old extenders (used, if need be) and those are not exactly costly either.

Which year are you referring to?

Lenses / Re: Low Light options

I believe your best option is to purchase the flash. You can use it for a lot of applications. I don't think it is such a good idea to purchase the mentioned lenses, because their image quality is not exactly a step up from your 15-85 and you would have multiple lenses for the same focal lengths without so many distinguishing features making such a purchase a good choice. Some people may argue against this, but I believe you will fare better with a good flash such as the 430ex. You then have more options later on to purchase additional lenses irrespective of your current requirements.

EOS Bodies / Re: Canon EOS 3D X [CR1]

This may be the optimized studio/landscape offering from Canon. The specs certainly look very good. I particularly like that ISO 25 feature.

I do wonder about the name, though. What if it is called 2D or 4D instead? The 3D has been rumoured for sooooooooooooooooo long, I don't think it is necessary to really release such a camera body, unless of course it has the potential to become a legendary body in this business.

Some of these specs appear to be reasonable, but some other parts make me question, if these specs are for real, because I feel it may be too good to be true.

Here's my take:
The 7D delivered many professional camera features, but it was available at a rather low price (compared to a 1D Mark IV). At that time the difference between a 1D Mark IV and a 7D (although obvious) was less pronounced as it is now with the 1D-X being full-frame and even faster. A successor to the 7D may thus be upgraded to the point of this being a rather affordable sports camera, possibly less effective compared to the 1D Mark IV, but coming closer. A 7D Mark II may therefore be in a similar position compared to the 1D-X as the 7D was to the 1D Mark IV.

Would this be wise? Obviously 7D Mark II sales would not cut into any 1D Mark IV sales and I believe they would not negatively affect 1D-X sales either. On the other hand Canon would likely sell more tele lenses, especially shorter ones. You can get easily into compulsive repetitive lens purchase mode with such a camera, buying a 135mm f2 (instead of 200 f2), then buying a 300mm f4 or 300mm f2.8 (instead of a 400mm f5.6 or 400mm f2.8). Then people may get into birding and buy longer lenses as well.

EOS Bodies / Re: The Mirrorless Future
« on: August 20, 2012, 10:38:59 AM »
I truly wonder why I shoot using the viewfinder most of the time and only on occasion use the 10x magnification in liveview? I don't think removing the mirror and prism arrangement does so many wonders for me. One of the biggest factors here is autofocus speed.

Given that in current cameras autofocus slows down using liveview autofocus mode, we should not expect that just removing a seemingly old-fashioned mirror and prism arrangement will make autofocus faster, because the camera also has to deliver image information to the viewer. How image data is handled in camera also affects how quickly it can be delivered on screen. I don't consider this a negligible factor. I do have my doubts about mirrorless cameras replacing DSLRs as long as I don't have autofocus at least being as fast as it can be using liveview. If using the viewfinder would slow down autofocus, then that would be different.

A mirrorless design may be able to get faster eventually, but when and at what cost? I fear that there is too much trust in new technology. We will have to wait a while, before anything spectacular might happen in this area.

I have only an older Mark II 2x extender, which I sometimes use with my 180mm. I have not had any problems with that combination on my 1DX. I can't say, if there is any difference in the Mark III extenders that may not be perfectly matched to such an old lens design as the 180mm. I am not sure, but since you have found no issues combining the new extender with newer lenses or combining an older extender with the same lens and body there may be an issue here with gear not being as optimized for each other as you would wish for.

 :D Thanks for the information.

I've got the same camera/lens combination. As soon as I get out of Europe (with intense levels of light pollution in my home area keeping me from astrophotography) I will want to try something like this.


I fear you are missing something here. The reuse of sensor technology for example from 7D to xxD, xxxD cameras is not a bad thing, but good business sense: Avoiding senseless investments in R&D.

But the sensor in the 1D-X is not the same as in 7D nor is the sensor in the 5D Mark III the same as in the 5D Mark II. It has a slightly higher pixel count.

The thing is that Canon felt compelled not to increase pixel count, but rather invested in making the rest of the camera better. This is what many people have been telling for years: Don't worry about pixel count only. Usually I have heard this from people loving their Nikon cameras.

Nikon came from a different situation, where they found themselves being limited mostly to just 12 MP for many years. It is surprising how often this is simply ignored by people praising Sony sensors in Nikon cameras. Of course Nikon must try to make up for what they must have perceived as a problematic restriction in previous years, while Canon was free to develop their gapless fullframe sensors, which now provide better pictures at the same resolution (except in Neuro's previously stated circumstances).

Don't forget that as a company you are in real trouble regarding 3rd party dependencies in case you have to use key components such as sensors delivered as it is from a competitor. It does not matter here, if a generation of these sensors is especially good or not. This problem is much more severe.

You will definitely need a crossover cable. Be careful though with operating system security settings, so that it will not block communications.

Technical Support / Re: New camera and Lens calibration
« on: August 15, 2012, 05:48:23 AM »
As far as I understand you will need calibration as a service only in case something is way off. Then it may be free, because you have received new equipment being somewhat on the fringes of acceptable production limits regarding autofocus.

Apart from that AFMA should do the trick, which I see as a standard operation to consider for all fast lenses. Lens IQ is not affected by calibration, only AF performance is affected, which in turn affects the IQ of your pictures severely, but only if using autofocus. For manual focus you won't find benefits.

Lenses / Re: Any updates on the 24-70 2.8 II lens?

Some traders in Europe claim that it is going to appear in September, but I don't know if this information is reliable.

Lenses / Re: What lenses do you own?
« on: August 14, 2012, 11:10:11 PM »
I'll list only what I use currently (I still own some old FD mount lenses and some other stuff):

14mm f2.8 - my favourite wide angle lens (I use it frequently on my 7d)
17mm f4 TS-E - great for architecture, if you have time for each shot
17-40mm f4 - cheap (for an L lens), but effective. It is a nice lens on full-frame, with a less useful zoom range on crop
24mm f1.4 Mark ii - I find myself shooting on 24mm focal length pretty often
24-105mm f4 - my favourite general purpose lens
50mm f1.2 - before I purchased the 85mm f1.2 my favourite portrait lens
85mm f1.2 Mark ii - my favourite portrait lens
70-200mm f2.8 IS Mark i - I still like this lens quite a lot (because of the nice bokeh)
100mm L f2.8 IS Macro - I must admit I bought it only, because I got it relatively cheap. Nice lens though
180mm f3.5 Macro - this is my favourite macro lens. It also works reasonably well with my 2x converter

I am currently using a 1D-X with a 5D Mark iii as a second camera and a 7D as backup.

I've been into photography for 27 years.

EOS Bodies / Re: 1DX Worth the Money?
« on: August 14, 2012, 10:35:48 PM »
The main issue should be autofocus speed and frames per second. If you shoot bursts with 6 FPS and you miss a critical moment and end up only with pictures slightly before or after that moment you may want to purchase a 1D. In the digital picture review of the 1D-X there is a list of camera response times, which I have found enlightening in this respect.

EOS Bodies - For Stills / Re: Discounts for the 1DX for Christmas?
« on: July 12, 2012, 09:55:35 AM »
Since it was possible to purchase the 1d Mark IV on several online shops, I expect the 1D X will end up there as well. The question is only when.

I expect prices will be more or less the same. Comparing previous 1-series and current 5-series pricing in shops I have seen there is much more variation in 5-series prices as Canon won't be controllng prices so much as with a 1-series body.
