EOS Bodies - For Stills / Re: 5Dc a good option?
« on: March 24, 2013, 05:58:33 PM »
The 5Dc is excellent, but has no liveview or AFMA, to big features that might matter to you.
It is excellent at high ISO's.
FF does not demand a better lens, its the opposite, just check the lens review sites.  The MTF is always higher for the same lens on a FF body.
 
You can also use the DXO tool to compare sharpness of a given lens on different bodies.  The 40mm has a 12mpix resolution on a 5Dc, but only 9mpix on a 7D
 
Play with it, a lens will have more resolution and rate higher on a 5D classic than on any crop body.  It gets even better on a 5D MK II or MK III.

It goes much faster if you limit to cross points and select a cluster of points as a group.  Moving a single point is pretty slow.

Maybe by then, Intel will have a superfast processor and SATA express will be out.  Current SSD's are limited by SATA III to about 500mb/sec, and huge image files take a lot of time to process.
At least Canon has options for sraw that you can select when you don't want full blown resolution.  With the D800, you get those huge files every time if you want to use raw.
That way a user would have a choice.

Yeah but sRAW isn't really all that RAW and with Nikon you can use crop mode FULL RAW which is great for wildlife since you maintain reach while not wasting storage on all the outer border areas so I'd actually WAY rather they went to the Nikon way of handling it.

I'd rather it be 39MP for perfect video and keeping 6fps than 47 or 50+ and being less than 5fps and having worse video.

Crop mode on my D800 crops the image away.  That's not useful to lose part of your FF image.  Its a feature added for those using the old DX lenses and turns the D800 into a 16mp crop camera.  I could use a 7D and get a cropped image with more pixels than a cropped D800.
If I had 1500 images to edit from a large MP sensor, I'd certainly try sraw or mraw.  I went looking for the feature after I got my D800 and had a day to edit 500 images, it was not fun to spend that many unplanned hours.

EOS Bodies - For Stills / Re: Overly Hot Hotspots On 5Dmk3
« on: March 24, 2013, 03:47:25 PM »
Hello all! This may have been addressed before so forgive me, but I'm just curious to see if anyone is noticing this on their 5Dmk3's.

I understand the 5Dmk3 doesn't have the best dynamic range, but does anyone else find hotspots to be overly hot? As an example, I was camera op on a short film the other day, and both the DP and I agreed to move to the 5Dmk2 simply because some of the things (i.e. lamps, televisions) were so drastically hot and were overexposed, where on the 5Dmk2 they were near evenly lit.

Also, I was walking around the park with a friend who had a 7D, and after comparing shots the shadows were much, much harsher on the 5Dmk3 at the same exact ISO, aperture, and shutter speed as well the whites being much hotter.

Now don't get me wrong, I love my 5D and have been blown away with it at times when I'm able to control the exposure of the subject, but I'm not really understanding why everything is so blown out at times. Is this a user error, camera error, or not an error at all and just how the camera handles?

Thanks, and I appreciate any responses.

What are hot spots??  Are you referring to infrared or sensitivity to heat? 
I could not find a definition online, is it a specialized term that some use in video?

4206
Do you actually believe that the number of megapixels means its the same sensor?  Perhaps you think the T4i has the same sensor, after its also 18mp, and then the T5i too.
Does the G11 have the same sensor as the old Canon 5D?  Both are 12 mp, as is the Nikon D700.

Not true, the viewfinder only gives you your burst rate which since I shoot in raw is only like 7-12 depending on settings. I rarely check the top LCD except for if I'm just pulling the camera out of the bag.
You are right, its always good to learn something, maybe one of my older cameras did display shots remaining.
 
A flashing light or warning would be good.
 
I see that mine displays 26 on my 5D MK III, while the top LCD displays 1999.

Lenses / Re: Canon Store having refurb sale right now
« on: March 24, 2013, 02:01:46 PM »
I see at the top in the address that it says USA.

Does this mean that you can't buy any of their refurb stuff if your from Canada?
That's true, unless you can have it shipped to a friend in the USA.

Another question is will they work on the next Canon DSLR? 
 
Twice now, when Canon updated lenses on their DSLR's, Sigma lenses stopped working because of errors in the way they reverse engineer Canon's lens system.  Those that had current production lenses could send them in for a upgrade.  It cost me over $100 to upgrade my 105mm macro, but my other 4 lenses could not be upgraded and became paperweights   They just gave error 99.
 
 
Since then, I've been very reluctant to invest big $$ in Sigma lenses.  Its not a savings if they will not work on future cameras.

Hopefully such a circumstance would be overcome with the USB hub. It should be able to update firmware as well as fine tune focusing...
I certainly hope so, but you would have to buy that hub, and it only works with certain lenses.

They actually start the sales late Saturday night, and many, if not most of the highly desirable lenses are gone by Sunday Morning.
I did get a 70-200mm f/2.8 IS L MK II last time, I'm hoping for a 24-70 MK II, the old 24-70 was up on the site briefly a couple of months back.

EOS Bodies - For Stills / Re: Warning on low card space
« on: March 24, 2013, 01:12:38 PM »
That seems like a nice feature.  I'd go to the Canon forum and suggest it.
 
I finally just got a big enough card to hold twice the expected shooting volume, and the same sized card for backup.  That way I don't have to worry, and I always have a backup copy if there is a failure.
 
Since I do not use the high speed shooting very often, its not a big deal If the SD card is slow.  If I were going to do video, I'd do a low level format on the SD card first though.

Do they actually listen to customer request there? Yeah, switching to 64 GB cards would probably help avoid this as well. I guess I just hate having everything on just one card. I guess with a camera with 2 slots though, that's where the backup slot comes in handy in case something did happen to your main card.
Suprisingly, they do!  Some of the announced updates like the ability to autofocus at f/8 , and the fix for slow autofocus  with AF assist lights came about thru user input.
 
They should be able to do it in firmware.  However, it might show in the viewfinder or the top LCD, and just looking at either place lets you see shots remaining, so I suspect that's their logic.
 
Perhaps if the shots remaining number flashed on and off, that might catch a persons attention.  A user could set the number remaining before it started flashing, as well as disable the feature if it bothered him.
 
 
Its just a question as to how important it is and how many users badly wanted it.  That's where a post on the Canon forum allows others to speak up.

How large is your card?  On a 32GB card I have shoot around 1,000 raw images.  Is that enough for a single event.  Costs are around $150.  Consider that 1,000 images is the equivalent of ~30 rolls of film.  Back in the day (ancient history) slides plus processing cost between $10-15/roll.  Digital equivalent of a roll of film (36 exposure) is only $5.

Double the card size, you will double the number of images.  Are you using the vertical grip?  If not, the battery will die before a 64GB card is filled.  A 128 GB card will outlast both batteries in the vertical grip.

If you are still worried about filling the card try setting the camera to use automatically switch to the second card once the first is filled.
Yup, using 32GB cards. I switched my first card with about 100 pics left on it and I filled up the second one. We tend to shoot quite a lot (in the 3500-5000 shot range). Not using a vertical grip although I'm curious if it might help me with the 70-200. I tend to use it a lot in portrait orientation and my arm was pretty sore by the end of the ceremony.

I'd consider a 128GB Card.  If your backup uses jpegs, you can keep using 32gb for the 2nd card.  It is a bit pricey, but might pay for itself.
Watch for sales :)

EOS Bodies - For Stills / Re: Tutorial on Auto ISO
« on: March 24, 2013, 12:50:30 PM »
I have tried auto ISO but have yet to get the hang of it.  Is there a good tutorial on it?

Ideally I would like to set a minimum shutterspeed, aperature and maximum ISO.  If the exposure could not happen, then I would like to specify which would be sacrificed.  Gets complicated very quickly.
On both your 5D MK III and your 1D MK IV, go into the menu system and set the maximum ISO that auto ISO will use.
Then select manual exposure and set ISO to auto.  Set both the aperture and shutter speed you want.  The cameras will adjust the ISO as required for a good exposure.  If it reaches the maximum ISO you have set and still cannot get enough light, it will slow down the shutter speed, so watch out.  See pg 166 of the manual.
 
With the 1D MK IV, see pg 112.

4215
Have you tried AFMA?  Cameras normally are not responsible for soft images, but autofocus accuracy is the common culprit.
 
Its very difficult to sort out issues with third party lenses, since both the camera and the lens cam be off but in tolerance but the error is cumulative.
 
You can test autofocus accuracy, your camera club might have someone to help you.
 
 
The 5D MK III has AFMA capability so you can fine tune each lens to give you the sharpest image.  Use it first.
