EOS Bodies - For Stills / HELP - strange 1Dx AEB behaviour
« on: February 16, 2014, 12:32:35 AM »
Or at least I think it is strange

I set my 1Dx to AEB (firmware v2.0.3) in manual exposure mode.

According to the manual, the camera should adjust the shutter speed.  What I observed is that the camera adjusts whatever is on the main dial.  When I have the aperture control on the main dial, it is adjusted.  When I have the shutter speed on the main dial, it is adjusted.

Is something wrong with my camera/firmware or is the quirk in the firmware?

Thanks

Thanks for posting.  I'm traveling and it will be very handy to review while I am on this trip.

Software & Accessories / Re: FoCal new version is out

Does this version add anything new?

Perhaps because if you need a whole bunch of cards, then whether you spend 50 bucks or 150 bucks does make a difference  :D.  And there's no guarantee that you will be able to use your cards in future as different standards come out and manufacturers switch to them....

If you indeed like to rattle off the frames, then the fastest you can afford indeed makes sense....

This is where I'm thinking lies. I can get a 32gb 160mb/s card for around $200 AUD and a 32gb 120mb/s for $120 AUD. I could get it off eBay but I'm worried about getting a fake....

I rarely shoot sport but it something I want to get into. I shoot more events and weddings.

I'd love to hear from someone who has both the 160mb/s and 120mb/s versions...

I just switched from the SD extreme pro 16gb (90 mb/s - the write speed was 45mp/s) to the new Lexar 1000x 16gb (2 pack for $99 at bhphoto)   

I noticed a difference in transfer speed as the Lexar reads at 150 mp/s versus 90mb/s...so it's noticeably quicker when moving files to the computer.

But with my 1Dx, I often shoot 8-12 frame bursts and I notice no difference in write speed between 45mp/s to my new lexar's 90 mb/s. 

So I doubt the extra speed will be noticeable for you if I don't notice a change from 45 to 90 mp/s...(and considering the SD you're looking at is 60 mb/s)

if i get some time i'll do a test (on my 5d3)  and see what the difference is between my old sandisk and new lexar when shooting continuous raw at 12 fps.

The change in write speed does not show up as a faster shooting rate on DSLRs. What it DOES show up as is a deeper frame buffer. The Canon 7D, for example, originally had a 15 shot frame buffer. When I moved up to 600x CF cards, my frame rate was still 8fps, however I started getting 23-24 frames in my buffer before it slowed down. After the firmware update, were Canon officially increased the frame buffer to 25 frames, I started getting 34 frames with my 600x cards.

The benefit of cards with faster write speed is longer continuous shooting times before you get reduced rate. You also clear out the buffer faster, so once you do fill up, if you wait for it to empty, it empties quicker.


Hi,

I just checked Sandisk's website and looked at the specs of the two cards I'm comparing.
The Extreme Pro 160 mb/s has a write rate of 150 mb/s and read of 160 mb/s.
The Extreme (or Extreme plus - some stickered/marketed) 120 mb/s has a write rate of 60 mb/s and read of 120 mb/s.
Does this ultimately mean I can shoot more and faster on the Extreme Pro compared the the Extreme (plus)?
Or am I confusing myself?
E.g. I shot a tennis game the other day, in particular a person serving, on a 5d3 and it felt like I didn't get as many shots due to slow down...? Am I missing something or is that the speed of the card I'm using (which was the extreme pro 160 mb/s) or just the FPS one the 5d3?
Key question is how fast can the 5DM3 write to the card.   I have not test these 2 cards, but with the older extreme and extreme pro cards (both 32GB) I did not a difference.  On the 1Dx, perhaps there will be a difference

Also you are correct to avoid eBay - I got burnt with fake cards years ago and now never go near them

Thanks for the comments.  The driving factor for this question is a trip to the Oregon coast this summer.   Of course I'll wait to make purchase, but stitching of water is not an option


Thanks again for the great thoughts

http://www.canonrumors.com/2014/01/review-sony-a7r-with-canon-glass/

that thread is on a fred miranda review using canon lenses on an a7r for landscapes.


thanks I saw that article.  that is why I am considering the Sony A7R.  Which is the better way to go?  Waiting for Canon may be a long time and if a body comes out it will be expensive.

Is there a good review of Nikon lens on the Alpha A7R?

Hi

I am considering buying a high MP body for landscapes.  Right now Canon does not a high MP body (5DM3 is 22 MP), not quite high MP.

As i see it, there are 2 high MP 35mm bodies - Nikon D800 and Sony alpha A7R.  I think both use the same sensory though there is a difference in cost - the nikon is 3300 vs 2300 for the Sony.

I think it will be easier to attach a canon lens (such as the 17mm T/S) to the Alpha as well as attach the Nikon 14-24 to the Alpha (is this true) than the Canon 17mm T/S to the Nikon.  Is this true?

Other lens to consider?  With the Nikon 14-24 is there any reason to use the Canon 14mm?

Other thoughts are welcome.

Thanks

The 'net is all abuzz over this product

http://fstoppers.com/how-to-clean-dust-off-your-dslr-sensor-sensor-gel-stick

My introduction to the fstoppers site was this review.......
http://fstoppers.com/the-fstoppers-nikon-df-camera-hipster-review
After that bit of false frivolity, I now take everything I see at fstoppers just as seriously I take http://newcameranews.com/ . I find New Camera News funnier though.
 
Seriously, I'll take technical and product recommendations from Kai Wong at digitalrev.com before fstoppers.


I just their review of the Hassy.  Very enjoyable.

Lenses / Re: 70-400/4.5-5.6 ... Why not 4.5-6.3?
« on: February 04, 2014, 11:19:40 PM »
At one point Canon a 500 F4.5 but then dropped it favor of the 500 F4 IS (original version).  Not sure but think there was some problems with AF and 500 F4.5 (but that years ago).

Software & Accessories / Re: How many cards?
« on: January 25, 2014, 07:09:54 PM »
When you format, did you do a slow format or a quick one?

When you do a full format, the computer writes over every block back to simple 1's and 0's.  It takes forever.  A quick format just marked everything as deleted and is consequently recoverable. 

I might be wrong about that, but that is my understanding.

I just format with the camera.  So for a CF card you don't have a choice.  With SD I do a low level format.

every so often I do a slow format in the computer.  This checks for bad blocks/sectors on the card.  The quick format (and in camera format) only clear the directory table.

Third Party Manufacturers / Re: Gura Gear Launches New Color for Bataflae
« on: January 25, 2014, 10:54:03 AM »
I appreciate the irony that an embarrassingly trivial announcement of a new backpack color quickly digressed into a discussion of using tupperware lids for lens caps, and it actually became a far more useful thread.  Now, if we can get Canon to put blue rings on the outside of the big whites we could have a yellow-and-blue makes green situation and know our lenscaps are on.

you just made my day....

What about pink.  Then my wife will gladly come with me and perhaps even help carry the gear :)

I hope this one will go to production.

Agree but want it to rival the  Nikon 14-24 for IQ

EOS Bodies / Re: Canon won't offer a high megapixel body
« on: January 24, 2014, 06:31:08 PM »

All in all, I'm thinking that a high megapixel body is becoming less and less appealing for manufacturers.


You are thinking rationally.  Forget logic, forget rational thinking.

If the manufacturers believe that such a camera will it sell or help the credentials of their current line up, then they will make it. 

Whether it is the best camera, whether it offers any new over current models has little importance.

The key question for Canon (I think, I am not an insider) will be will it be profitable and will it be accretive to margins.

Returning to differentiation, the challenge for Canon and Nikon is to be relevant in the days of camera phones.

Impact on the high market is close to zero - tho some pros are giving courses on iPhonology and producing interesting work. 

Impact on low end dSLR and P&S market is large.

Time for the big boys to get creative and produce innovative products that will appeal to the masses, not to those of us are a "photographers" but to those who take snapshots
