Canon General / Re: A Rundown of EOS 7D Mark II Information
« on: August 16, 2014, 06:06:44 AM »
The EOS M totally missed the market in the USA.  Even the EOS M2, with its dual pixel focusing, isn't going to hit the USA Markets.
Where did you read that M2 has dual pixel focusing?

Just try buying a modern bicycle with no research and see what you end up with.

A tricycle? With 3 wheels it must be an improvement over a bicycle!! ;)

Bah  Unicycle.  2 wheels is soooo 20th century.  Clearly the technology has advanced to the point where the product should be smaller.
I concur, we'll run production on unicycles until we run down stock of the old sprocket-and-chains. When unicycles become the norm we can reintroduce the "retro-cool" bicycle targeting the discerning hipster crowd
Yea, unicycles, unicorns and Canon will make a big splash this year  ;D

Lenses / Re: Canon EF 11-24 f/2.8L Coming [CR1]
« on: August 07, 2014, 09:05:32 PM »
I love the 16-35 focal length , but I need the f2.8. So for me I wouldn't mind it if canon released a 16-35 2.8 iii.
Do you guys think that with the release if the 16-35 f4 is means that my dream won't come true?
As I said, I'd love a 16-35 2.8 iii too.  But maybe Canon want to do something else to show innovation and at the same time compete with Nikon.

I was too excited when I read it. This year I have done some landscape astrophotography.

Then I thought:

I have used mostly my 14mm 2.8L II. In very few cases I have used the TS-E 17 (in some cases the corrected verticals were worth the light loss).

This 11-24 will have to be close to perfect to make me even think of it.

The reason is that half of my 14mm 2.8 II shots would benefit from a (future?) 16-35mm 2.8L III (with no coma).

Its hood with combination of a flat front element would protect from flare from non-avoidable car lights.

The 11-24 wouldn't be protected just like my 14. Its only benefit would be a slight  increase in expose time (at 11mm) say from 25-30 sec to 35-40 sec (and hopefully less coma).

IPX Standard Code Meanings

That is exactly what we need for cameras and lenses.  I am sure that Canikon would be very resistant to submitting their products to such a standard.
So you mean that instead of producing weather resitant bodies, they are ... IPxx resistant companies ?  ;D

...I felt it would be too much trouble to get the targets printed at various sizes, hanged 100% vertically and use proper lighting (which I do not have).

Just to point out…if you test at a distance that's a fixed multiple of focal length (I use 25x and 50x), the target is always the same relative size.  Personally, I just use an inkjet print of the target on letter-sized heavy matte paper for all my testing.  Also, it does not need to be hung perfectly vertical, as long as you have a ballhead it's easy to align the camera to the target at a slight angle, and the software guides you through that.
Thanks for that. So I guess this leaves only the lighting not being correct. As for distance, I have 14mm to 500mm but up to 200mm I sometimes shoot from not too far away (especially for 85m 1.2) so I guess I can make a compromise and test shoot from a little closer than 25X. But even so when I use the 85 the lighting is even less than my living room's so maybe the lighting is of no issue (it is incandescent type by the way so at least it is the correct type).

Canon General / Re: Which Lens to Take
« on: August 07, 2014, 08:21:30 AM »
Provided weight is a concern I'd take the 5D III, 24-105 and the nifty fifty.

Also, above, plus if you think you'll need longer reach and have funds available, consider getting a 70-200 f4 IS (that can be sold when you get back)
+1 It seems a nice compromise. Plus the 70-200 f4 IS is light.

A few of my lenses looked like rubbish or made the camera seem so until I microadjusted them. I did not even use focal.
A trial and error AFMA for my 85mm 1.2, 135 2 and 35 1.4 worked miracles on all my cameras.

Now something funny:
5DMkII No1:  85 1.2L II +10
5DMkII No2:  85 1.2L II +10

5DMkII No1:  35 1.4L +10
5DMkII No2:  35 1.4L     0    !!!

I think that your trial and error method has something to do with this point. I first tried trial and error, then dot-tune but was never satisfied about the results. The tolerance was there. Focal, which uses statistics behind the screens, is taking care of that error. Focal really looks for the top sharpness. I also think that a 34 1.4 is less sensitive to afma then a 85 1.2. I see that more or less also on my 24 1.4. The longer the lens the more critical. The wide angles have a much wider DOF, so simply by trial and error finding the top level of sharpness doesn't seem simple to me.
I would buy FoCal (if you have a lot of gear it is value for money anyway) but I felt it would be too much trouble to get the targets printed at various sizes, hanged 100% vertically and use proper lighting (which I do not have). So I used trial and error and I am satisfied.

Plus a correction: My two cameras are 5DMkIII not II (but the principle is the same).

EOS Bodies / Re: Plan B

i don´t care much about aps-c.

im only interested in the 7D MK2 because i want to see what canon does and if there will be an improvement in sensor technology.

Seeing the 7D mainly as a tele/action/sports camera probably something along the lines of a good phase detection AF + improved DualPixel technology. Maybe QuadPixels. Possibly initial focus acquired by the dedicated AF sensor, then handing off to Sensor focus to follow the objects and shoot at a high frame rate without moving the mirror. This would require a hybrid viewfinder.

So for sensor technology this doesn't mean necessarily mean very much improvement in regards to quality of low ISO still images. I wouldn't expect too much in this regard.

the rumor mill says there will be new sensor technology: "As well as some revolutionary sensor technology".

together with the hype around "canon will do something historical" or  "a big change in canons history" (as mentioned a few times at CR).... i would be disappointed by only a updated dualpixel technology.
+1 Exactly! Dual/Quad/Whatever pixel technology is nothing compared to a much improved sensor.

I got a TG-3 and quite enjoyed it. It was used mostly at the surface though and anyway not deeper than 1 meter.

And I would love a f/1.4 lens wider than 24mm with very good edges/corners and no coma (for obvious reasons  :) )

Lenses / Re: 50mm Coma Sigma Art vs Regular Sigma F1.4

@extremeinstability: thanks for this and generally for all your coma tests. They are very useful.

Still looking for a very wide, very bright lens with not much coma.

I know that you  would suggest the Samyang 14 2.8 but I had found a used (but excellent) Canon 14mm 2.8 II for about 1000 Euros less than the street price. After getting rid of old gear I didn't want I paid about half of the used selling price. So I took it and left happy  :)

True there is a little coma at the corners but nothing serious like my now sold 16-35mm 2.8 (version 1).

Changed my mind. Not selling any of them. At least for now.
Hmmm, you sound like ... myself  ;D

Big splash could be the sound of a new big zoom waterproof camera dropping into the water  ;D
