Marsu42, I think I've probably read most of the threads and it was still hard to make the decision, that is until the price was right.  That really helped but still this keeps going around in my head.  What is so challenging is user versus camera and personal biases.  You'd like to trust a given person's judgment/ability but you never know for sure, although certain folk are very experienced, unbiased and trustworthy so .......

Jack,

I have both the 1D IV and the 7D II.
Go back to your cropping thread for birds. That is what it comes down to.

With the 7D II when it hits you will have a super sharp image that you can crop tighter with greater detail. It adds a bit to that ability. It will give you a bit more sharpness to work with than the 1D IV.

With the 1D IV you will have a body with an AF system that hardly misses. Your little flying bird, it will be easier to get this pic with the 1D IV. If you miss the shot with the 7D II, how much resolution does the 7D II have? It has none.

I took the 7D II out this weekend, I had one situation presented itself with a running bird that I wish I had the 1D IV.
The 7D II missed and it would have been the shot of the day. But for the rest of the day the 7D II did just fine.
This is really useful information. Do you have an opinion of 5D3 in comparison with 7DII and 1DIV for birds in flight? That would be very interesting for me to know.

Because of the frame rate I never considered the 5D III for BIF. That is why I never bought it over the 1D IV.
I have an opinion, which is the 1D IV would be better because of frame rate. From what I have read I believe the 5D III would track very well. Probably not on par with the 1Dx but close.
Thanks for answering. Not being a pro I was thinking the 7DII for cases where I am FL limited. But for now I will stick to my 5DIIIs and save money for the next iteration.

EOS Bodies / Re: Possible Canon EOS 5D Mark IV Spec Talk [CR2]

Every time there is a megapixel advance some people claim "no one needs that many pixels etc. etc. etc."; they said this at 3 mp, 5mp, 10mp etc.  More pixels is always better if you don't have to give up anything (not sure yet what the 5ds will require us yield).

ISO 6,400 limit with expansion to ISO 12,800 (same as the pocketable S120 with 1/1.7" sensor, by the way).
I suspect that the quality will not be the same  ::) ::) ::)

YEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEES.

I guess it is rather obvious I agree with this specification  ;D ;D ;D

That is assuming it will be a really low light and high iso beast  ;D ;D ;D
If something sounds too good to be true, then it is not true. ::) :P
I agree, I have already changed the emoticons. Plus, that is why I said: "assuming"  ;)

Most important for me is: EC in Manual when using Auto ISO
+1000. This is the best they could add.

Over 26% of respondents say they are going to buy one, that is a crazy good uptake rate for such a specialised tool.

My guess is that this number will drop dramatically once more in-depth reviews with the actual camera hardware are out and people realize just how specialized 50mp is concerning pixel-level sharpness and casual keeper rate.

And with the 5d4 on the horizon, the 5ds might just be a temporary hype quickly forgotten about the next shiny marvel of technology that will *really* enable you to take those great pictures :->
+1000 That summarizes best the way people think  ;)

Canon EF Prime Lenses / Re: Canon EF 600mm f/4L IS II USM

It's also great for other space stuff. Orion's Sword:

Over 2h 20m total exposure time

That is an awesome shot! It's pretty amazing that you can do that with camera equipment instead of a huge telescope.  I can't imagine waiting over 2 hours for an exposure - I get impatient when I do 90s exposures!  Also, do you do the second dark frame exposure as well with such a long exposure?
Awesome indeed. I do not have complex equipment for tracking, just an older version of Astrotrac which when polar aligned (as much as possible with its mediocre system) can give me a 10 to 15 times tops increase in exposure time (without star trails).

So I was thinking despite my 500 f/4 to use a much wider lens like 135mm f/2 or a 85 1.2 and to crop.

@epsiloneri: interesting demonstration of coma. Thanks. I believe though that the photos from Samyang apart from the exceptionally low coma exhibit yet another property of Samyang: Decentering  :(

Where are all of the messages about how it won't autofocus correctly without sacrificing some virgins and doing a rain dance?
If it has NO coma I will not care about autofocus. I would use it fully wide open in manual focus for landscape astrophotography. That way I would be less afraid for future incompatibilities (there were some Sigma old lenses that used to work only fully open in modern digital cameras).

P.S Now, Some virgins - although not sacrificed- would be nice  ;D
P.S2 I wouldn't use this lens at a rain dance though as I am pretty sure it wouldn't be weather sealed  ;D

...release a UWA for full frame that matches the base aperture of their chief competitors FF UWA.

Someone is sleepwalking over there.

Did you miss the part about 11-24mm? 

Oh, you wanted 11-24mm f/2.8.  Here, carry this instead.   ;)



You'd likely need this to pay for it...


Hey you exaggerate a little but basically yes it would be heavier and pricier. But it would be a dream landscape astrophotography lens... :-\

It's like comparing apples to oranges. Why dump the 5D3 for something that is not a super set?
5D3 has 1fps more and  (more importantly) higher ISO capabilities.

13
I will skip it (as I already mentioned in a similar thread).

All I want is a 5DMkIV with the same Mpixels as 5DMkIII with better high and low ISO performance, 8 fps and much better DR (maybe using the Canon Dual-Scale Column-Parallel ADC Patent...).

Which means you know my answer to a future poll when 5DMkIV arrives  ;D

EOS Bodies / Re: Who is going to buy the new 5Ds's?
« on: February 04, 2015, 12:53:34 PM »
If all we get is resolution I´m out. If we get (significant) improvements in noise and DR, I´m in. I have seen enough (condescending) proof from my Nikon 810 buddy (with Otus 55/1.4) to accept that Canon has a significant challenge.

If it turns out to be FF 7DII type sensor performance, I´ll be very disappointed  and probably go for the Pentax 645z. If so, I´ll sell off a majority of my EF lenses and limited Canon to action, birds and wildlife.

I suspect we are seeing 50MP, because Canon might not be able to compete on the lower ISO DR quality front. They are over-compensating for other inadequacies.

If this thing is 16bit with massive DR, then the market will probably justify spending the money on it. Otherwise, it bodes very poorly for the near future of Canon tech, in terms of market perception.

I would only buy one of these cameras if the price was down to $3000 or less.
In that case I think I would prefer a Sony sensor in the short term but I think it is better for Canon to develop their own sensor in the long term...

Now that it looks like the cameras will be priced around $4k (as I feared), I think this will go on the waiting list

You *actually* though it'd be like the 5d3 starting price at $3.5k, even if the 5ds has the premium flagship tag attached and is lacking current competition from Sonikon? Oh my, I'd love to have part of your optimism in some parts of my life :-)

If the new Canon cameras use a Sony sensor, what will you call the new Sonikon empire?  By the way, my interest is in the "R" version.  Before I invest in the 11-24, I plan on using my Nikon to Canon adapter for the Nikon 12-24mm lens which I know is hot stuff and testing the D810 vs the "R".  It will be interesting to see what the extra MP's do with my 36x24 prints (if any).  I too am interested in whatever dynamic range improvements this might mean (if they use the newer sony sensors I expect quite a jump - lower ISO like the D810?).
Hmmm. let me try first:

1. CaSoNikon.
2. SoNiCanon
3. SoCaNikon

 ;D ;D ;D
