Technical Support / Re: Sensor cleaning technique that actually works?
« on: September 06, 2012, 11:15:25 PM »
Cleaning a sensor is something that takes experience.  It took me about 5 tries before I started feeling happy with the results.  I first bought pre-moistened sensor swabs.  They had too much moisture and streaked.  Then I bought dry ones and learned the right amount of eclipse to use.  I also learned to make just one swipe with a swab and toss it.  Using it for a 2nd swipe made the sensor dirtier than when I started.
I now have Canon CPS gold, but have not had to clean my sensor, so my three clean and check coupons are about to expire.

You now have to pay for using EOS Count, while Astrojargon is free and both give the correct results for a 5D Mark II.
A refurbished camera will not read zero, I bought a 7D as well as a 5D MK II grom the Canon refurb store.  Both had a few hundred actuations using eos count on the 7D and Astrojargon on the 5D MK II.

Lenses / Re: new ziess 55mm, redefining?
« on: September 06, 2012, 10:54:23 PM »
As I recall, their existing 50mm f/1.4 does not gather very good reviews on a FF body, so its time to make something thats better. 
Photozone gives it 2-1/2 stars for optical quality, while the much less expensive Canon 50mm f/1.4 gets 3 stars, and it has autofocus as well.
"Some years ago we analyzed the Zeiss Planar T* 50mm f/1.4 on an APS-C DSLR and the results were truly impressive there. However, on a full format DSLR the performance leaves a bit to be desired actually. The lens is capable of delivering great results at medium aperture settings - no doubts - but it disappoints at f/1.4 and f/2 with a rather poor border/corner performance and generally reduced contrast.  Depending on the use-case this may or may not be overly relevant (e.g. portraits) of course. The light falloff is on the high side here but that's a rather normal characteristic for such lenses. Lateral CAs are well controlled and not overly field relevant. The quality of the bokeh is pretty good although the weak contrast may spoil the game at f/1.4.
Just like the rest of its family the Zeiss lens is built to the highest standards. Some users may complain  about the lack of AF but this isn't really a significant flaw for a wide-angle lens. The focus confirmation  is available in the viewfinder (ZE version) and in very critical (close focus) scenes Live-View can give  you the needed guidance. That said, it remains a bit of an anachronism these days. The price level is quite steep so you really have to have a itch for such classic lenses."

Lenses / Re: Need advice on indoor low light lens choices.
« on: September 06, 2012, 02:02:15 PM »
One stop faster (f/2.8 vs f/4) is not going to make a big difference.  Even a f/1.4 lens might be marginal.  I usually use my 35mm f/1.4 in low light and crank up the ISO to 3200 or 6400.
At some point, a external flash is going to be needed.

EOS Bodies - For Stills / Re: Anyone buy a new 5D3 on eBay?

Keep checking Canon price watch.  There are some good prices from authorized dealers. 

Software & Accessories / Re: Cheap student and teacher Lightroom 4
« on: September 06, 2012, 12:07:36 PM »
I'm suprised that a student version is shipped by Amazon.  My son (a student) has bought the student version in the past, and Adobe always shipped it, but only after he sent a photo of his student ID, or some other way of proving he was a student.
Maybe with the lower prices, its no longer required?

Lighting / Re: TTL + remote simultaneously?
« on: September 06, 2012, 12:04:20 PM »
If I am reading your question right, the remote flashes are "Manual"?  If thats the case, using TTL via the on camera flash will not give a accurate exposure, since the effects of the manual flash units will not be taken into account.

You can report it, but Canon may not do anything.  I'd return it to the store and complain.  It is very possible that they did not know and it was supplied by a crooked wholesaler.  They will tell you that in any event.
It will probably work fine, but you overpaid for a poor imitation.  The AC section looks poorly designed, and might be a fire hazzard.

EOS Bodies - For Stills / Re: 5D3 ignores microadjustment in LiveView
« on: September 06, 2012, 11:53:17 AM »
As Neuro said, the 50D defaults to quick AF mode in Live View, which uses AFMA.  If you change it to "Live" mode in theh setup menus, it ignores AFMA, simply because it uses Contrast detect to focus, so AFMA is irrelevant.
The 5D MK III has Live mode as default, bu you can change it to quick mode.

While the 5D MK III is a excellent camera, I sent mine back.  The inability to see the AF points in dark rooms is a killer.  I can see the much larger 7D AF points, but not the 5D MK III.
5D MK II's were available for under $1600 over labor day, and I bought a 2nd one after returning my 5D MK III thru CLP for $1407.
If I catch one of the 5D MK III's that is through a authorized reseller for $2800, I'll probably go for it, but $3500 is too much.

EOS Bodies / Re: A question about dust...
« on: September 05, 2012, 11:56:33 PM »
I think I have a far greater tolerance for dust than most.  I did not clean my 5D MK II for almost two years, and by then it was really dirty.  Even so, I only noticed the dust when viewing at large image sizes.
I do have a sensor cleaning setup, and have a long working length inspection microscope that I use to check it after each pass of a sensor swab.  It usually takes 5 swabs to get it clean.  A few seconds later, I can see microscopic bits of dust begin to settle on it.  There is no such thing as perfectly clean, its just a matter of how large the dust particles are, and how many.

PowerShot Cameras / Re: Canon PowerShot G12 Digital Camera
« on: September 05, 2012, 11:49:38 PM »
I get your point about buying a G12 on sale especially if the improvement is only incremental but I wonder what is meant by the latest comment.

More PowerShot announcements are expected, a G12 replacement I’m told is likely, as well as a new fast lens PowerShot.

What is meant by 'Im told is likely' a guess, an unsubstantiated rumour not even a CR0?

I had not noticed the difference in the ISO differences between the G11 and the new P7700 and anyway I wonder how you can say that you used the G11 at such a high ISO as when I used it at high ISO for a night shot I found the resulting image almost unusable because of the high noise level even using noise ninja I was unable to produce a satisfactory image at that level.
Actually, it is my wifes camera, and she used it at ISO 3200 at a theatre rehearsal in very low light.  She doesn't know anything about ISO settings, someone set it to 3200 for her. Truthfully, I was suprised that she got anything at all.  Then, I also tried it at 3200 the next night, and it was far better than I expected, even though far from wonderful.  It works fine as a small print.  The drawback to theatre use is the slow shutter speed, so you do get motion blur.
My point is that, if the P7700 has a far better sensor, why is it limited to 1600?  Small CMOS sensors may not perform as well as CCD, even though they are backlit and use less power.
At any rate, here is one of the ones she took.
G11, ISO 3200, f/4.5

Here is one I took at the next night's rehearsal also at ISO 3200, but with my 5D MK II and 35mmL at f/1.6 and a much faster shutter speed.


EOS Bodies - For Stills / Re: Raw, mRaw, sRaw of JPEG
« on: September 05, 2012, 08:43:32 PM »
My D800 needed sraw, my 5D MK II or MK III does not.  Unfortunately, Nikon does not have SRAW or MRAW.

Out of Camera Raw files are seldom all that wonderful.  You usually need to at least set the processing options in your image editor, and will likely want to tweak the images.
I have a 7D and a 5D MK II.  The 5D MK II blows it away in every way but when I am focal length limited.  My 7D is also good with my 100mm L macro.  I also use my 7D for product photography, simply because the 15-85mm Zoom matches it well even at close distances.
I would not hesitate to snap up one of the 5D MK II bargains available.
Do be aware that its very likely that you will be wanting longer focal length lenses, all your lenses will suddenly appear to be much wider.

Technical Support / Re: 5D Mark II Won't Turn On

A good possibility is a bent pin in the CF compartment.  You need to get a flashlight, and have very good eyes or a magnifier.  Look inside for a bent pin or even more than one.
If you did not remove the card after your previous use, then a bent pin is much less likely.
If it is bent, it can occasionally be recovered as long as its not severely bent.
