If they like "playing" with the sensors they might as well make a lower noise/higher DR one  ::)  ;D  8)

Technical Support / Re: Help me save this photo!
« on: July 02, 2013, 11:15:27 AM »
Scratched negatives and slides is one of the reasons I like digital photography. In fact I was sorry I decided to turn into digital by the end of 2007.
I should have done that earlier.

Anyway photoshop can fix many problems  given ... time (and disk space but that is ample nowadays).

May I suggest to make the corrections in a different layer so as to make the process non-destructive?
(you create a new layer , you select it, check "Sample All Layers" and then start making corrections)

With that way you will be able to keep all corrections to the new layer, have your original photo intact and be able to repeat the process.
Just remember to keep all layers and save it in PSD or TIFF format.

EOS Bodies / Re: 70d price discussion & poll results
« on: July 02, 2013, 07:52:56 AM »
So, are you ready for the next poll?

Canon's official list price for the 7DMkII will be (body only)...  ;D 

844
$100 off...soon will drop to $1500;)

The price in the picture is the kit price with lens, and even that changed to the latest [cr] - obviously Canon lowered the price in the meantime to counter Nikon...

.... but the pre-order price is released and THE RESULTS ARE IN (this is also in the first post):

25% of you were correct
12% guessed too low
63% guessed too high
- don't you Nikon trolls trust our favorite brand to be reasonable :-p ?
Hey not Nikon trolls at all here (I do not have anything Nikon - not even a PS)
Unfortunately price increase is ... so Canon nowadays  :(

19 AF points and a D-pad. To whomever said it would need a joystick, sorry...told ya!   :P

Joystick will be in 7D II with 1D X or 5D III 61points AF system - 10fps ;D
Now, that was the worst thing to say. Everyone will wait for that camera and will not buy 70D at all  ;D  ;D  ;D

Well, that ought to DRum up some DRead from the DRoll DRones who DRool over DR, and DRag many a forum thread down the DReary path of DRivel, DRaining into puddles of DRoss.

Loctite Blue 242 is 'semipermanent' - a good hard pull with a long-handled hex key and the screws will come out.  But they won't work loose on their own.  Loctite has other products with a much stronger 'permanent' bond.

RRS doesn't use distributors - you buy direct from them. They do ship internationally.
Once more 100% precise. Thanks  :)

Lenses / Re: What's the Difference: 1.4X EF Extender 2 Vs. 3
« on: July 01, 2013, 09:11:44 PM »
I have some purely sentimental reasons to not try to get rid of my II teleconverters though.
The version III cannot be used with any analog bodies except the 1V. The best analog bodies I have are EOS1n.
That and the fact that I will not be able to stack them (but that is mostly for fun).
However 2XIII tempts me. (Maybe next year)

I owned both 1.4x and 2x extenders V.II for use on my 500/4 V.1 and 300/2.8 V.1 and when they V.III extenders were released, I upgraded both.

I didn't really see any  noticeable difference with the new 1.4x (perhaps just a tad in the corners) but I did find a noticeable improvement with the 2x on both lenses.  Across the entire frame.  I rarely used the V.II 2x because I was never really happy with the results.  Now I use the V.III 2x all the time and am very happy with the IQ it delivers with both my 1D Mark IV and my 5D Mark III bodies.

If I had it to do again, I would not bother to upgrade the 1.4x extender for my use.

Just my personal experience, for what it's worth.
It is worth. I have always been satisfied with my EF1.4X II but until recently the only use of EF2X II that was really worth was back in 2006 when I had used my 300mm f/4L (non-IS) with that 2X teleconverter and photographed the total eclipse.
An improved 2x teleconverter is always useful.

Thank you very much. Better more detail than less.  :)
And anyway I can go back to this when necessary.

I have a non-gripped 5D3 so I believe the problem will be a little less.

I am aware of possible Markins head limitation and when I use it I will be very careful.

Right now I (think I) have no access to an RRS representative in Europe but I have already ordered the Kirk plate and replacement foot so that's it for a year.

I understand that eventually the correct thing is to use a specialized head but the use of this lens will be mostly for:

1. Sunsets/moonrises/sunrises (with extender or not)
2. Wetlands visits. This will be a first!

Lens arrived on Friday 21st. After a rather unfortunate choice of place on Saturday
I found the correct spot next day (full moon day) and that day was rather a success.

Since I did not have either a lens plate or a replacement foot I reverted to my old Manfrotto 055PROB with a Junior Gear Head 410 head.

Now the advantage of this head is that the plate can be used either with a 1/4 inch or a 3/8 inch screw.
I used the later and the lens was steady (with the help of mirror lock and 2 second delay anyway).

This combination is perfect for the sun and the moon but is useless otherwise.

So I am thinking of Markins as a compromise for now.
(Another choice I am contemplating for the next year is the replacement of M20 with an Arca Swiss Z1)
But first I need to test the combination...

By the way isn't the use of glue bothering you with the thought that you are somehow bound to that choice?
Is its use permanent?

Again thank you very much for your response.

Lenses / Big white lenses: Foot replacement or Lens plate?
« on: July 01, 2013, 04:30:21 PM »
hello,

having bought a 500mm f/4L IS II and using a Markins M20 head - which for at least this year will NOT be complemented with objects named Wimberely, Gimbal, Sidekick etc - I wonder if the best choice is a lens foot replacement or a lens plate. Since a friend is coming from the States where almost everything is cheaper I decided to test both! So I will get Kirk LP-58  and Kirk LP-55SG - the reason for Kirk is my positive experience with their Camera plates. I will have them in about 2 weeks.

I have the following thoughts:

1. LP-58 comes with 2 1/4" screws and a 3/8" adapter.

My 500mm requires 3/8 and 1/4 screws (one per category) so the adapter will have to be used. Do you have experience with these adapters? Are they safe to use?

For example when you decide to remove the plate which one will unscrew first adapter with the screw or just the screw first and leave the adapter in the lens plate and me scratching my head wondering how to fix it

2. LP-55SG means removal of the original foot. Will the screwing of the new foot be secure? Canon suggest to leave this to them which of course is silly so what is your opinion? Is the replacement safe? I guess it's both safe and trivial...

On RRS site they say:  "If your mounting screws loosen over time, consider using a drop of LocTite 242 for better security. "

There is nothing like that on Kirk's site but I think RRS are being more sincere...

3. Any comparison between Lens foot replacement and use of lens plate?

Sorry for possibly silly questions but I am newbie as far as big white lenses are concerned.

I just got 500 II, paid a lot and if the difference is so small as negligible I prefer to not spend more money for now (I have version II teleconverters).

If you only shoot the moon and other things which move slowly or not at all, there's not a substantial benefit to upgrading.  But if your subjects move, the improved autofocus performance with the MkIII extenders is reason to upgrade, if not for the IQ benefit.
I have read that autofocus speed decreases by 50% with EF1.4X III and by 75% with EF2X III.
Are there any measurements with version II ?

Another point is Canon III extenders don't stack because of the protrusion (perhaps it's for weather resistence, but probably more for preventing us from using them in ways they weren't designed -- Murphy-proofing).

It's the extra elements in the 2xIII.  You can still stack a 1.4xIII behind a 2xII.  With the MkIII extenders, you can put a 12mm extension tube between them to stack...if you're willing to take the IQ hit from stadking, that is...
This is a very interesting piece of information. Unfortunately it seems to me that the weakest link in IQ is the EF2X II so if I were to upgrade I would first replace that very lens.

They are a tiny bit sharper, probably not worth upgrading unless you are super critical, or, of course, if you have one of the new super-teles at $10K +, why not.
Have you verified that? I mean there  are tests at TDP some of which show the III just a little better but some show them equal. I was thinking about version II telephotos in which case I guess everyone would say go for version III but come on have you made comparison tests? Even TDP has tests only with version III.

I am writing this because I just got 500 II, paid a lot and if the difference is so small as negligible I prefer to not spend more money for now (I have version II teleconverters).

In addition, EF1.4X II is excellent. If I were to update I would update EF2X II.

On the other hand I happily stacked them in a  non-critical case like a moon photo.
 
This cannot be done with version III...

Lenses / Re: Used 300 2.8 L IS Mk I
« on: July 01, 2013, 01:17:36 PM »
The older lens looks essentially new -- not even a mark on the tripod foot.
Then it is probably less used and/or more well taken care of. So it must be a better choice.

My 600 II doesn't have a mark on the tripod foot, either.  Of course, that's because 5 minutes after first unpacking the lens, I swapped out the Canon foot for the RRS replacement, and packed the Canon foot away in the case.  ;)

 ;D  ;D But still a heavily used lens will show signs of use on other places...
