When you put a 1.4 converter on your lens, you can be sure that the autofocus is a bit slower.
Buying a 400 mm F2.8 and combining it with a converter does not help you much I guess.
If you want to spend money, buy a new 500 mm or 600 mm. With a 600 mm you have more reach and it' s even fast with the new converters type 3. What about a 1Dx?? It has an amazing fast autofocus.
Possibilities enough.

Have my 1Dx now for a couple of months. Send it twice to a Canon service center for cleaning. It did help a little bit.
When it arrived the sensor was very dirty. Canon must shame itself a little bit for delivering a top tool as dirty as it was. Altogheter I've spend several hours to clean it, but the dust is very difficult to remove. It is now on a acceptable level, I don't have to remove 50 or more spots a frame anymore.

For the rest, great camera with an outstanding autofocus.

1-1. The function to disable the Image Size selection button is added.

S___, S___, S___,....... to late.

Shot yesterday some nice aggressive action between two males Snow Bunting, some of them are really nice.
When I loaded the pictures up to the computer I was amazed by the huge numbers that fitted on the card.
Unfortunatly the image size was changed to M1 and even not the highest quality. Result, images not even the size of 3MB.

It was a cold day with a windchill factor of about minus 11 degrees Celsius, so I was wearing big gloves.
I even had a moment in wich I was wondering how many frames I was still be able to make on that card, but it did not trigger me enough to check it out. Stupid mistake.

Software & Accessories / DPP and dust delete data
« on: December 28, 2012, 04:32:53 AM »
Who has experience with using '' dust delete data'' ?? ( Canon EOS 1D X )

Although I' am still waiting for the DPP-disk wich was not included in the box from my new camera, I ' like to know if it is possible to use this tool in a batch. Is it working properly and does it not effect your images???

Normally I import my images into Aperture, throw away the ones I don't want to keep and do some adjustments. Then I transform the images I want to sent away  into JPEGS and remove sensordust with Photoshop Elements. After a holiday I have often 3000 to 4000 images to go thrue and to make a selection using DPP is not ideal ( open them one by one ).  To do this in a batch should be great, but I never have used DPP.

Thanks for your help.

Very nice job. Can you tell me what the temperature was?
At the end of february I'am going to Kamtsjatka. Temperatures can drop there to minus 40 degrees Celsius, but will be normally around -25 degrees.  We go camping on the beach!!!!. I' ll take my 1D mark4 AND 1D-X and hope they keep working.

Thanks.

What was wrong with the former system???
Black focuspoints are much less usable then red ones in certain conditions. And that is what it's all about.
If a new system is developed, make sure it is a better one, at least as userfriendly as the former one.

I think the point is versatility. With the etched screen, all the points are there, all the time (and 61 densely packed points is a lot!).  With the transmissive LCD, you can choose to display only the active point(s), there's an easy visual indicator of regular vs. spot AF vs. expansion, you have an on-demand viewfinder grid as opposed to needing to swap a focus screen, you can have the electronic level displayed in the VF, etc.

IMO, there are big advantages to the LCD.

You've got some good points and I do use some of them. I'am not familiair with all the technical details I have to admit. But still, the blinking is very distracting and I have never liked disco. I turned it off already, it drives me a bit crazy. I would like to see some more information about when the lightning meter is fooled and how big is the impact. Canon should give us the option to be red all the time, the blinking option or to turn it off. I mostly shoot in daylight condition and I suppose there will be no effect during these circumstances. In this way it's not nice to use.

Make it solid, nobody complained about it with former cameras. It's not logical thinking. Must be a smaller problem to fix then to achieve the AF-F8 problem.

It's a technical problem.  Previous models used etched focus screens, so the points could be illuminated with a more focused light from a more oblique angle.  The AF points are on a transmissive LCD, and that required a more direct illumination angle with a broader light source.

You seems to know the technical aspects!! What was wrong with the former system???

Autofocus at F8 is great, but the blinking red light is terrible and certainly not usable for people suffering from schizophrenic and epilepsy ( no joke and no I'am not ) )  Make it solid, nobody complained about it with former cameras. It's not logical thinking. Must be a smaller problem to fix then to achieve the AF-F8 problem.

In regard to an article, the red light can foolisch the lightning meter in some cases,...... they think.
Oke, how large can be the effect and amongst what kind of conditions????

Make the light solid an provide the possibilty to turn it off or reduce the intensity of the red light

EOS Bodies - For Stills / Re: 1dx, or d800e?
« on: October 14, 2012, 04:48:36 PM »
The only down side to the 1DX I heard on these forums compared to the 5D3 was its shutter noise was louder than that of the 5D3. I think you should consider that...

I don't have experience with the 5D3, but compared to the 1D4 it is much less.
You have to find out yourself, do you really need the big megapixel. Or is it more the idea. To whom you accountable explain.

Software & Accessories / Re: What are most people using for processing RAW

I use Aperture for a seven years now. The workflow is really easy to work with, but I hope with the next version, they have been taking a good look at Lightroom. That graduent filter is a great instrument. In Aperture noise reduction and remove sensor-dust sucks. I use Elements 4 for that, it works much easier!!!!!
Also the instrument ''dodge and burn'' could be much more sofisticated. Now the treatened part always becomes brown, even when that colour is not in the subject.
And, write a user guide with less nonsense talk, just come to the point. A lot is not explained.
When you copie your images to an external harddisk, every new pack of images that you have imported to the library is stored like that. Why not maintain a simple structure like maps and submaps with you see when working with the library. Just the way you build up the library.
I'am not very happy with it, but I don't like to learn the pretty different workflow of Lightroom. There is a lot to improve in Aperture.
Sorry for my English.

EOS Bodies - For Stills / Canon 1Dx, 500 mm, converter and vignetting
« on: September 02, 2012, 04:51:05 AM »
With the arrivel of a confinding juvenile Bairds Sandpiper on the Dutch coast and the first serious photography with my 1Dx, I discovered a complete new phenomenon for myself. The 1Dx is my first fullframe camera. I took my pictures with a ( type 1) 500mm/F4 and with a 1.4x converter ( type2 ) attached. With an aperture set on 5.6 there is obvious vignetting noticable. It disappears pretty much when the aperture is set to 7.1. So far I only knew of vignetting with wide-angle lenses. Compared to my mark 4, I have to trust the much better image quality at iso's above 500.
Is that a phenomenon occuring only with the older 500 mm, or is it due to the use of the converter? Does it also appears with the new telelenses?

By the way, the bird was not getting an very nice welcome. It was sand-blasted a lot on our sandy beaches.

Thanks,

Hello Richard,

I've tried that first, but then also you have to hold the button. To photograph BIF is hard working and it should be of help if you don't have to think all the time '' do I push the button hard enough''?. Moving around with autofocuspoints is what I do all the time.
Another point what I noticed, when you shoot with the 180 mm macro, you're limited in the numbers of auto-focuspoints. Often I use manual focus, but sometimes AF can be used. That was the fact with the Mark4, but there is always something to complain ( F-8 autofocus !!!!!)
A positive notice, iso 640 on the Mark4 is now something like iso 2000. And that is one of the reasons I bought this camera. And with some noise reduction it looks very clean and small details are still present.
With this camera the next '' big spend'' will only be when they impove the dynamic range significant.

Greetings from Holland, Europe

Since 4 days I ám lucky to own a 1DX. Have not done really much with it, but so far looks like a good improvement according to my 1D4.
I was hoping for a quick custom function to change from ONE SHOT AF to AI-SERVO mode. What I don't like is that I have to hold the button. Often you have to choose an AF-point depending from what directing the moving subject is coming from, or you select all the time the AF sensor in the middle. And, depending of the background you have to set an compensation ( sky as background ) Is should be working easier in my opinion if you just one's have to push a button to make that switch. If the subject is gone you can go back to the one shot AF by pushing the same button again. With a steady subject you often have more time to change your settings. I don't like the grip if you have to hold the button all the time in the heat of the ''battle''. I agree wich the two missing settings for action photography ( AI-SERVO and High speed continuous ) although I standard select continuous shooting.
