EOS Bodies - For Stills / Re: 1Dx replacement speculations.
« on: February 26, 2015, 04:11:01 PM »
For the 1DX Mk2 I would like a price and weight reduction - I don't think either would happen!
I am quite happy with the MP count, though a little more might be nice so long as there were no compromises.
I am sure many would welcome more DR, personally I am not that bothered as it has yet to be an issue, but more is still better.
Improved video? Don't even know how to turn it on and can't be bothered to find out how.
More FPS? No thanks as mine is set to 10 fps = plenty.
Overall, except for it's price and weight, I can find no significant limitations in my 1DX - but then I thought that about my 1D4! I am sure the next incarnation will give us better performance that will become "Essential" once we have tried it.

Here's what I've thought about getting for this type of situation (but haven't bought, yet):

That looks a bit like a home made rig that I made to carry my 100-400 when I had it. I am currently looking at a more substantial version of my Mk1 using a redundant Think Tank backpack strap and a 4 inch Arca clamp for my 800 F5.6 or 300 F2.8.
The principle is great and works well but I have yet to try anything with a Big White. A local photographer uses something similar with his 500 Mk2 and walks for miles with it, I think his rig is home made as well but I am not certain.

Interesting thread that explains what I had observed in the past but had no explanation for. The differences that I noted were less but still there.

I would echo "Vern's" comments, though my personal combination is a 1DX + 300 F2.8 L IS Mk1 and an 800 F5.6 L IS.
The Canon 300 F2.8 (any version) is simply a superb lens and takes extenders VERY well. If you can carry/afford a longer lens then that is a better solution. However if you need mobility then the 500+ mm lenses start getting in the way - this is where the 300 F2.8 scores.
The 400DO Mk2 is still a bit new on the market. I have tried a few of the Mk1 versions with mixed results. They varied from barely adequate to 2 of the sharpest lenses that I have ever used! The 400DO Mk2 is looking very interesting but I think we should give it a little longer to prove itself before making specific recommendations.
Combining reach and mobility is always difficult so you need to work out exactly what you need and then decide on an appropriate lens.

Ouch!
That is bad news. Having had my home invaded 4 times I sympathize. Luckily, for me, they never got much but it is scary nonetheless!
Don't dwell on it, get what you can from the insurance then just get on with your life. Don't let the Scroats who did this get you down! If you do then they have won.

I believe that you are supposed to cut them out yourself from larger sheets. For reference the guidelines on my 17-40 are 31mm square, hope this is of help.

Not quite certain what you are getting at.
The 1DX uses 3 processors (2 x Digic 5+ and 1 Digic 4) as opposed to 2 Digig 6 in the 5DS so I would expect there to be differences.
The quoted burst depth on the 5DS is 14 RAW files, with my 1DX (at 10 fps) I get 50+ RAW files before things slow down - perhaps this is the difference?

Sorry dilbert but I don't understand what you are trying to achieve with some/many of your posts.
You often post useful and insightful advice/information and then come up with complete twoddle like this!
Please don't take this the wrong way but do you think that you may suffer from an internet version of Tourette syndrome?
I am not being flippant, I am just concerned.

Looks like a VERY interesting lens - but I shudder to think what it may cost!

Lenses / Re: Best birding/wildlife combo?
« on: February 06, 2015, 05:54:59 PM »
Just a thought but have you considered selling your crop camera and getting a used Canon 300 F2.8? Much as I loved my Canon 300 F4 it is not the lens that the F2.8 is so the 300 F4 could go as well to help with costs. You will loose a bit on the minimum focus distance and gain a bit of weight but I can assure you that it is worth it! I went through a similar dilemma but I am really happy that I went to the 300 F2.8 and Full Frame.
This is a personal view, but I have yet to find a crop sensor camera that I am happy with for wildlife (with the exception of the 1D4). True with a full frame camera you do loose apparent reach but (with cropping) the loss is less than the crop factor would suggest - though it is still there. Against that is the fact that your 5D3 will operate at ISOs that will allow you to actually get the shot!
For reference my "walkabout setup" is a Canon 1DX + Canon 300 F2.8 L IS + 1.4 Mk2 and 2 x Mk3 extenders - the 2 x Mk3 works surprisingly well on the F2.8 and is passable on the 300 F4.

I read Thom's post, frankly I think he may have been skipping some of his medication!
However if mirror-less suits your needs then go for it! I have tried a few and can find no practical use for them so far - but if they suit you then fine.

EOS Bodies - For Stills / Re: POLL: Do you need 1/8000s shutter speed?
« on: February 06, 2015, 05:09:29 PM »
The original 1D managed 1/16000 sec according to DP review:

http://www.dpreview.com/reviews/canoneos1d

If they could do that back then why can't they do it now? Would it be used often? I doubt it but on a "Do it All" camera like the 1DX  I think this sort of facility should be available. After all there are some (me?) who fancy the idea of freezing insect wings, or at least getting close!

Because the shutter curtains are traveling at the same speed, the 1D curtains had less far to travel than the 1DX curtains.

And the 1/500 sync is due to the fact that the 1D had a CCD sensor so had an electronic second curtain.

If you want to freeze insect wings do it now with equally short, and shorter, flash duration speeds.

As mentioned, it's a 1.3 crop camera.  But no 1.3 crop cameras after that could.  But can we see some of your 1/8000 second images with motion blurred insect wings?   And how much light do you plan to dump on the insect?  I shoot with a f2.8 and have to use ISO 400-800 to get 1/8000 sec exposures in full sunlight.  Are you sure you won't light you insects on fire?

I've considered getting a 1D just to shoot 1/16000 sports photos, they are $100-300 on eBay.  Still I think I'd shoot 2-3 good ones and then stick it in the closet.

Not quite sure that I have properly interpreted your post, however my point was that "it would be nice to have" and that they could do it in the past. Also that, in their flagship models, manufacturers should incorporate  everything they can. Maybe you won't need some of the features - I certainly don't, I haven't even looked at the manual to find out how to turn on the video function as life is too short!
Would I like higher available shutter speeds - yes. It is no biggie but it might be handy/interesting occasionally. There are lots of other things I would like as well such as 6 ISO etc..etc.. The shutter speed thing is something that we know they can and have done.
Incidentally if you look at a slow motion sequence of Canon's shutters working one can see that (at high shutter speeds) the exposure is effectively a slit between the shutter blades that passes over the sensor. Therefore the exposure speed is determined by the speed of the blades and the size of the slit so sensor/film size is not important.
This is not a new idea (see Leica focal plane shutters) or the fixed shutters (slits) that RAF cameras used in the 1940s producing the characteristic strip images that my father's squadron (RAF 225 Sqdn) used to shoot in 1942/3.
There may well be issues, such as durability or Auto Focus, which make such high shutter speeds impractical but if this is not the case then I would like to have it.

Lenses / Re: How much will EF 600mm f/4 IS ii hold it's value?
« on: February 05, 2015, 06:23:42 PM »
Difficult to say really.
2 years ago I bought a used Canon 800 F5.6 L IS at a bargain price - but now I would be lucky to get my money back. About the same time I bought a Canon 300 F2.8 L IS and could expect to make a healthy profit if I sell it. Additionally I wish I had bought a Canon 500 F4 L IS 5 years ago as I could have beaten it about quite a bit and still sell it for more than I would have paid!
It's a lottery. Do you really want this lens? I do - it is a cracker! If so buy it, use it, love it - you will be waiting quite a long time for something significantly better.

EOS Bodies - For Stills / Re: Monopod - advice what to purchase
« on: February 05, 2015, 06:14:22 PM »
I can thoroughly recommend the Gitzo GM2541 if you want a small/light Mono Pod that will hold pretty much anything - used to use mine with a 600 F4. I would also suggest that a ball head on a Mono Pod is normally a hindrance.
Looking at your post - are you shooting video or stills?
For stills a Mono Pod can be a real asset (especially without a head) but I think it would be a disaster for video. Please note I have no idea about video (I don't even know how to turn it on, or care to find out) but I do know a number of video shooters and their mantra is big, heavy tripods with the best (biggest) fluid heads that they can afford.
