Lenses / Re: 6D kit lens 24-105 F4L or 24-70Mark 1
« on: September 29, 2012, 11:22:41 PM »
Let me say I know the Mark 2 is better in every way then the Mark1 but I have to scrape together money for the 6D body let alone a 2K lens.  So I'd debating weather I buy the 6D kit or just body and a 24-70mk 1

If it helps people answer... I don't' pixel peep or anything crazy, I'm in the group that if 90% of the population who are not photogs think it looks good then that's all I need.
Get the kit.  Its a bargain.  The Mark I is overpriced, and used 24-70mm L MK I lenses are nortorious for problems.  Roger Cicala of lens rentals has found some apparent reasons for problems with 24-70mmL lenses with high usage.
 I have had several used 24-70mm Mk I lenses that were not very impressive, they just did not seem to be as good as they should be.
Personally, paying a very high price for a used one might lead to grief.  If its been inspected / repaired by Canon, its likely OK. Lens Rentals does do a resolution test on their used lenses before they sell them, so thats a fairly safe bet.

EOS Bodies / Re: Shutter count request to Canon.
« on: September 29, 2012, 11:14:28 PM »
Here was Canon's response so far..
Thank you for contacting Canon product support regarding Canon camera.

I do not recommend 3rd party website's such as the one you described but for a different reason, they are generally not accurate. I do not know what is possible to do through the EOS Utility program. I will certainly forward your suggestions  to our software team for their consideration.

Sincerely,

Jeffrey
Technical Support Representative

That is true - generally, but a few actually use Canon's SDK to get the information.  They have discovered by trial and error how to get the information, and its accurate.  Canon does not advertise a shutter count in their SDK, but there are lots of undocumented features.  Eos info and eos count along with foCal all get information by using the Canon SDK.  Most of the others merely look at the image number, which is almost never correct.

Software & Accessories / Re: who uses Focal or similar?
« on: September 29, 2012, 09:40:33 PM »
I have used Focal with great results. It is a program suited for studio and "set up" photographs as the micro adjustment changes with the distance you are away from the subject and such. If you take photographs of subjects that are "always" the same distance away from you and you "always" use the same focal lengeth, then it is perfect! :)

Thats true, but it has nothing to do with Focal, its a lens property.
Some lenses change their AF point depending on distance to the subject.  FoCal merely shows you what is happening.  Typically, lenses front focus as you get nearer to the subject.

I wish there were a macro setting for the 100mm L, I'm certain that the AFMA value will be a lot different at near macro distances.

It wasn't for me. For the 100L Macro on my 1D X, it was +4 at 50x FL, +2 at 25x FL, and +3 close up (filled the frame with FoCal's tiny target).  On the 7D, it's +2, +3, and +2, respectively, and the 5DII was -2, -1, and 0.
My 5D Mark II seemed to have a big difference, but I did not use FoCal at the time.  I'll check my new 5D Mark III with the lens.

All EOS bodies do this, its a tolerance buildup thing.  Its been known since they came out in 1987..
There is a slightly oval shaped hole on the lens portion of the mount, and a round pin on the body that drops into the hole when the lens is locked in place.  Depending on the tolerances of the body and lens, it might be snug or move a bit.
Another thing that happens, particularly with the larger lenses is that that oval hole becomes worn or elongated, and then there is more movement.
In any event, it does not affect operation or accuracy of the lens.
Someone seems to be "Discovering" this over and over for 25 years now.

EOS Bodies / Re: Shutter count request to Canon.
« on: September 29, 2012, 08:13:18 PM »
Most of the free apps to check shutter count just plain works of fiction and do not work. 
EOS Info is free and does work, but only on certain camera bodies.  eos count, the one costing $1.49 has been around for a while now, and is deemed safe.  You use paypal to pay, so none of your credit card information is exposed.
I also discovered that Reikan FoCal is returning a correct shutter count for my 5D Mark III, so if you are doing AFMA, its a extra bonus to be able to get the shutter count.  I don't know exactly which bodies are supported.

Lenses / Re: Rumors about general porpouses lenses for APS-C
« on: September 29, 2012, 11:25:52 AM »
Dear all of you,
I am a 7D owner and I am waiting to deal for a new lens, a stadard one like 15-85 ("f/ is not good" bla bla bla) but I need one compact for trips.

Do you think that Canon will develop any new lenses for new APS-C rumored bodies in the near future?
If not I'll make a Christmas present with ol'15-85.

Thanks in advice !

17-55mm 2.8 Is worth the extra $$$.
I loved my 17-55, but sold my crops and the lens.  When I repurchased, I bought the 15-85 because it matched the zoom range and MFD I needed. 
Both of them are well worth their price.

Pricewatch Deals / Re: Big Canon EOS 5D Mark II Price Drop Coming
« on: September 29, 2012, 11:23:20 AM »
I just sold my refurb 5D Mark II for $1750 a week ago.  It only had 735 actuations, over 300 of them put on it the weekend before.  I needed money for my 5D Mark III, and keep enough cash on hand to grab a deal on craigslist for a "L" lens if a bargain pops up.
$1699 seems like a deal.  The original 5D was blown out for about that price in a few days, then those who held back new ones were able to get more.  With the 600D coming out, that might not be the case.

« on: September 29, 2012, 11:18:17 AM »
purchased the Focal software and just did it on my kit 24-105 @105 and my 50 1.4.

results:
50mm 1.4 needed +9 adjust
24-105 needed +5 adjust at 105mm

is that usual?

I have now done most of my lenses (I've a ton of old EF film lenses that I may consider some day).
Here is the results so far, and a typical report that FoCal Pro produces.
 
This is my table made to keep track of my settings in case I happen to lose them.  Zoom lenses have two settings, while primes have one.  I wish there were a macro setting for the 100mm L, I'm certain that the AFMA value will be a lot different at near macro distances.
Most of my lenses are close enough to be set to zero, but my most used lens, the 135mm L, along with my 85mm f/1.8 need AFMA.  I have yet to test the 35mmL, I overlooked it or would have done it when I had the 16-35mmL setup for 35mm.  Same for my 50mm f/1.4.  Doing a AFMA for my 15mm FE would not likely make a difference, but I'll do it anyway.

 
 
Table produced by FoCal.  As you can see, the lens had a AF issue one time.  I was outdoors, and the wind was blowing gently, so a gust might have moved the target, or just the lens misfired.  It happens more than you might think, and FoCal shows it.

There are three excellent lenses for crop, the 10-22mm, the 15-85mm, and the 17-55mm.  They pretty well cover the wide to short telephoto range.  There is also the 18-200mm which is not spectacular, but does cover a wide range.  We keep hearing rumors of a newer version.
The 40mm EF is also excellent on crop bodies and low cost.

Canon General / Re: Dream Package for Soccer (Football for those elsewhere)
« on: September 28, 2012, 07:12:57 PM »
Maybe just better to call it soccer.  Most know what it is. 
Football refers to many different games depending on where you are.
 
Football refers to a number of sports that involve, to varying degrees, kicking a ball with the foot to score a goal. The most popular of these sports worldwide is association football, more commonly known as just "football" or "soccer". Unqualified, the word football applies to whichever form of football is the most popular in the regional context in which the word appears, including association football, as well as American football, Australian rules football, Canadian football, Gaelic football, rugby league, rugby union[1] and other related games. These variations of football are known as football codes.

Lenses / Re: Wide or ultra-wide angle with excellent corner performance
« on: September 28, 2012, 07:04:20 PM »
Zooms are a compromise, the Zeiss 21mm is pretty much the reference standard, as is the TS-E 17mm.  For ordinary mortals, those are the best.  You can undoubtedly get a cinema lens that is better, but the price is out of sight, and they will likely only cover APS-C.

Here is part of a test report.  each AFMA setting has the data and the image of the target which shows the sharpness.

EOS Bodies - For Stills / Re: FoCal likes the mk3 AF
« on: September 28, 2012, 05:49:03 PM »
I have now managed to get most of my main lenses calibrated, but ran out of time today.  I was very pleased in general with the AF consistency.
I've tried to past in a chart of the results.  I did not have the inclination to test the 100-400mm L at 50X on the 400mm focal length setting, so 30 ft or so was it.
I also like the comprehensive pdf format test report that can be saved for each lens (Focal Pro).  It also records the camera shutter count, which I was not aware of.  I had exchanged some info about the possiibility with Reikan a few months back, but haven't had a reason to use the software until now.
I'll try to post a typical report, if I can get it into a format that can be viewed.

Lenses / Re: what filter for my first "L" Lens
« on: September 28, 2012, 04:39:56 PM »
And that juicy tidbit is the only good thing to come out of selling my 10-22 when I went FF. (I plan on getting a 17-40 and have an extra B+W filter lying around for it.)
You should lose very little when selling your 10-22, used, they are about the same price as a 17-40. I am not a big fan of the 17-40 on FF, but if stopped down, its fine.  Perhaps mine was just a poor copy, it happens.  It wasn't bad, just did not seem to inspire me.
