Marsu42 - I watched KA2, like, just, 3days ago. Enjoy your Super Holidays dude.

Yup, thanks, I'm enjoying it!

Until the end of the year, I have superpowers too and feel free to write stuff like "just afma your lens" or "if your 6d's af doesn't work just fine, you're not up to the task" instead of trying to present a differentiated opinion :->

Btw: KA2 didn't really impress me, the first one imho is much more fun even if it is heavy on college humor.

What is KA2 ?

Wow! Thanks for the replies folks, that was unexpected. :o  Sorry about posting in the wrong area.
Health issues have put an end to my Photography. >:( Consequently, I have lost interest in my research lab.
Of all the people who could have responded, the five who have, I have the highest respect for each of you. Its kind of spooky...

Marsu42 - I watched KA2, like, just, 3days ago. Enjoy your Super Holidays dude.
Valvebounce - Hi Graham, happy to be helpful man. All the best to you and yours, yeah!
Mt Spokane Photography - Hope you can recover some of your Polaroids. I've had some experience, maybe I can offer some tips/tricks.
distant.star - I'm not Jack. But I thought it was by Ray Charles ? Still one of my fav's anywhoo.
Don Haines - Thanks for the info', and interest.
CR Backup Admin - Thanks. I can appreciate your 'modus operandi'.
Hmm, so maybe I'll stick around a bit longer. Stay tuned for more Foot-In-Mouth action. ::)

Safe and happy holidays to all of you.
Glad you are going to stay.

BTW, did you pour your own glass? I must confess to having given the occasional thought to trying the charcoal bbq method to melt a silica mixture into glass and then to try pouring it into a mold and grinding a simple lens or two out of it.... make a telescope like Galileo :)

I've never had one lost, but I did have one B&H order go awry.  UPS ground from their NY warehouse to Boston is overnight, but I watched the tracking updates as the package went from New York to Deleware to Philadelphia.  Last I checked, Boston was in the opposite direction.

I called B&H, they sent another shipment that I received the next day.   :)
We had a FedEx order that went from New York to Atlanta to London to Atlanta to London to Atlanta to London to Atlanta to Montreal to Ottawa.... In hindsight, B&H could have used a bicycle courier and it would have gotten here in half the time, but this was most obviously the fault of FedEx...

EOS Bodies - For Stills / Reikan Focal VS Dot Tune to AFMA lenses on a 7D2
« on: December 21, 2014, 01:19:42 PM »
I have heard claims that "Dot Tune" was a reliable method to AFMA a lens. I have also heard claims to the contrary. Most of those claims have been long on opinion and short on data, so I decided to give it a try myself on a 7D2.

The results are as follows: (under incandescent lighting)

150-600: dot tune (150 +9) (600 +14) - Reikan   (150 +5) (600    +6)
  70-200: dot tune ( 70 +7) (200   +4) - Reikan   (  70 +2) (200    +3)
  17-55 : dot tune (  17 +4) ( 55    +3) - Reikan   (  17 +5) (  55   +9)
   10-20: dot tune (  10 +4) ( 20    +9) - Reikan   (  10 +5) (  20 +17)
      100: dot tune (100  -8) - Reikan  (100 +5)
       30 : dot tune (  30  -2) - Reikan  ( 30 +1)

I changed locations, repeated the test and got the following: (under flourescent lighting)
150-600: dot tune (150 +11) (600 +17) - Reikan   (150 +5) (600    +6)
  70-200: dot tune ( 70   +7) (200   +5) - Reikan   (  70 +2) (200    +3)
  17-55 : dot tune (  17   +4) ( 55    +3) - Reikan   (  17 +5) (  55   +9)
   10-20: dot tune (  10   +3) ( 20    +7) - Reikan   (  10 +5) (  20 +17)
      100: dot tune (100   -10) - Reikan  (100 +5)
       30 : dot tune (  30   +1) - Reikan  ( 30 +1)

The observations are:
1) The Reikan values stayed the same between the runs
2) The Dot Tune values varied up to 3 units between runs
3) Reikan and Dot Tune only agreed once.
4) Reikan and Dot Tune can disagree by up to 15 AFMA units

If you look at the discrepancies under the two runs.
incandescent - 4,  8,5,1,1,6,1,  8,13,3
fluorescent    - 6,11,5,2,1,6,2,10,15,0

it appears that Dot Tune is affected by fluorescent lighting.

A quick visual verification of the extreme cases indicates that the Reikan values are far more accurate that the Dot Tune values.

My conclusion. At least on a 7D2, don't waste your time using Dot Tune on your lenses, get Focal and do it right.

EOS Bodies / Re: Ron Martinsen Blasts the 7DII in his review
« on: December 21, 2014, 12:53:56 PM »
the incredible display of ego around the comment about his picture being the best a Canon sports shooter could expect from it . . .   Just a quick look around other reviews should have told him that others are not having the same difficulties he had and should have made him think again before hitting that publish button.

I think you've touched on the key here: so many photographers hold up their own personal experience (anecdotes) as examples of what can be done and what can't, what should be done and what should not, and forget that their personal experience may not match the experiences of others.  While personal taste is appropriate for the artistic component of photography, it's more an exercise in engineering to decide how to use the equipment to collect the most and best data from each click of the shutter.

I guess this is the difference with the scientific community.... peer review....  Do your tests, compare them with others, and if there is a discrepancy, try to figure out why...

moving back to the point.... the review.

Those pictures were terrible. If I were to consider a camera based on those pictures, I wouldn't touch it. The focus is not there, the lighting isn't there....Has he AFMAd his lenses? Does he have it set in some AF mode where it is focusing somewhere other than where he thinks it is?

who says they would change the mount distance for a FF mirrorless?

If/when canon brings out a FF mirrorless, would it be possible to have a built in adapter for EF lenses?

Surely they'll over some means of transition, or people are bound to take the opportunity and switch to another brand. However, with the film-lens distance ef is designed for, the adapter will be quite awkward esp. for smaller ef lenses and counteract the "small camera body" opportunity of mirrorless.

That's probably the reason why there isn't a ff mirrorless from Canon (yet) and their ef-m lens lineup isn't very large: They're still unsure which way to jump and if to produce a new ff mirrorless lens line.

As they did when transitioning from FD to EF?  Just sayin'.
FD was mechanical. EF was electronic. it was not practical to produce an adaptor.

Technical Support / Re: Alternating colour shift in sequences of photos
« on: December 20, 2014, 03:57:44 PM »
Yes, it's the color temp of the lights changing (flicker).  Enter the anti-flicker feature of the 7DII...
Or use slower shutter speeds such as 1/125.

Yes, that would work great for couches and walls, and people posing for shots.  Not so good for kids running around.
I think Neuro is right.

When I got the 7D2, one of the things I had to try was the anti-flicker mode. With it turned on, the burst were all the same brightness and the same colours.... when I turned it off, the brightness and white balance was all over the place....

I am sorry, but the reviewer lost all credibility when he started to complain about noise at iso 100 when zoomed in 100%. That is like looking with a magnifying glass at a picture the size of a 4x5meter wall. O MY GOD SO MUCH NOISE.

"This image looks nice at first until you zoom in at 100%, there is so much noise at iso 1600!!!"

http://photos.ronmartblog.com/img/s6/v141/p250641345.jpg


And then he continues to rant how bad this camera  is for a sports photographer. Yeah right, i am pretty sure 99% of the sport photographers out there dont print larger than the size of a newspaper that you can hold with 2 hands easely and publish in websize format on websites like facebook. Heck, very few sport photographers actually earn money these days since the market has been completely destroyed anyway. What the hell is he talking about?

Fact is, at iso 3200 and higher all the images produced are still pretty useable for newspapers and facebook (LOL!)
3200? for facebook? you can probably run it up to 51200 and be good enough for facebook :)

I haven't used the 7D2 yet, but I hear echos of when the 7D came out.  Folk wowed by the specs and then underwhelmed by the images.

I got my 7D around 6 months after launch (let the beta testers break theirs first, save a third) and I quickly came to the conclusion that those not getting decent AF hadn't bothered setting up the AF system, particularly the Ai Servo preferences, and those who were getting too much noise were either shooting jpeg or messing up their RAW workflow.

I was, and remain happy with results up to 3200 with careful post processing, but as with all APS-C cameras, the lower the ISO the better.

I wonder how many people buy something like the 7D or 7D2 and expect it to work brilliantly out of the box?
Thats what the 70D class of camera is for, and would probably suit reviewers like Ron a bit better.

I was about 4 weeks in having shot speedway, soccer etc before I had my 7D tuned to work in line with my shooting methods.  It wasn't a frustrating experience as I could feel the keeper rate improving and the camera getting better and better at tracking.
 
The headline spec changes of the 7D2 aren't enough to tempt me just yet.  Besides I want to see what Canon come up with in terms of 4K.
+1

When I first got my hands on the 7D2, I had a poor keeper rate due to autofocus problems..... The more I use it, the better the rate gets. I can do stuff now that the old camera could not handle, and I am still learning.

Is a photograph an accurate depiction of a scene, or is it art and to be manipulated to emphasize a feeling or a concept? Or is it both or is it neither?

EOS Bodies / Re: High Megapixel Camera Coming in 2015 [CR3]
« on: December 18, 2014, 10:04:42 PM »
remember folks..... we are talking about a FF camera with the same pixel size as the 7D2. It will have very similar IQ to the 7D2. It will have very similar ISO performance to the 7D2.

You can't have the megapixel count of tiny pixels and the performance of large pixels. You can have one or the other... or a compromise. You can't have both. The 6D, 5D3, and 1DX will be superior in low light.

That's why I think it will be a new series, not an update of an existing series.

I bough the 6D to be a low light camera.  I do not care if it has the ISO performance of the 7D II.  I want a very weak to non-existent AA filter High MP camera for landscape.  I would like an articulating screen because I to most Landscape on a tripod in live view.  It is very helpful be able to adjust the.   screen to a better viewing angle.

Yes tiny pixels = miserable ISO performance. 

I really do not see them replacing the 5D III for 2 more years.  As an event camera what is wrong with the 5D III?  I really do not see anything.

The 5D3 has to be about the best general purpose FF camera out there.... I can't see Canon messing around with it.... I really doubt that a new high megapixel camera would be a 5D4

You're off the rails.  Just making the sensor bigger - with the same sized pixels - will improve high ISO performance by 1 1/3 stops.

Oh, and in-general, smaller pixels perform better at all ISOs than larger ones.  The only exception is very extreme high-ISOs.
:)
I wonder how the sarcasm impaired will act?
