Third Party Manufacturers / Re: D810 users are seeing spots
« on: August 21, 2014, 12:53:24 PM »
The 5DII problem has been solved via a firmware update (If I recall correctly 1.07). I remember this issue because solving it was a prerequisite for me to get a 5DII...

Now, to defend Nikon, if I had a D810 and I was doing a long exposure I wouldn't even think of using it at crop mode.

If problems can be solved in firmware and companies are willing to do so all is well.

Post Processing / Re: Post processing, coma removal

It wouldn't!

The choices are:  Peripheral Illumination, Chromatic Aberation  (R & B), Color blur, Distortion.
Thanks for the info.  It looks like this is something that you need to get right during the capture unless there's some tool out there that can do this PP.
Exactly! The best solution is another lens as was suggested before.

By the way the Canon 24mm 1.4 has terrible coma.

So there is a CR2 that we... "will see new products"  ;D ;D ;D ;D ;D ;D

EDIT: This could be a CR3   ;D ;D ;D ;D ;D ;D

EOS Bodies / Re: 5D3 No Longer in Production
« on: August 17, 2014, 08:09:59 AM »
I was at a major retailer today (I will leave their name out but it rhymes with 'chest guy') and I was asking them to price match the 5D3 for me. While they were looking it up they pointed out that their system indicated Canon is discontinued.

The system said they will still have the 5D3 in stock through 2017, but could the fact that they are no longer manufacuring new units be an indication that a 5D4 is coming soon than expected? Is this just an errorr on thier part or is this something that is already known to everyone but just news to me?
Honestly, I believe that your retailer rhymes with bed sheet...

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?

EOS Bodies / Re: Canon to Make a Big Splash at Photokina? [CR2]

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.

Lenses / Re: Canon EF 11-24 f/2.8L Coming [CR1]
« on: August 07, 2014, 06:40:34 PM »
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
« on: August 07, 2014, 07:57:35 AM »
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.
