1D X FPS limiting factor?

Malte_P said:
what is limiting the maximum FPS for the 1D X?

is it the bandwith/processing power of the DIGIC5+ CPU´s?

or is it the mechanical shutter construction?

could a dual digic 5+ powered camera deliver 10 FPS for a 21-24MP sensor?

To return to the original question, the 1D X as far as I know is beyond any SLR before in terms of frame rate for a moving mirror at 12 FPS, and also beyond any DSLR's data throughput at 216 MP/s (18MP 12 times each second, it's max in RAW mode).

While both of those are pushing the boundaries, as to which is forming the actual limit, only the Canon engineers will know. However, it's likely the mirror assembly is moving as fast as they could get working reliably at that price point, and the data throughput of the dual digic 5+ at 12 FPS would have been pushed too far with one of the many 20+ MP sensors they have put in every other full frame body released since the 1Ds mk III.

Therefore they're probably both right up at their respective limits, in balance with each other.

To answer your last question, based on the above assumption of an upper limit of 216 MP/s, at 10 FPS a dual digic 5+ camera could work with a sensor of up to 21.6 MP. Any more MP and the frame rate would have to drop further.

And the rumoured 46MP camera with the same processing pipeline would max out at 4.7 FPS - if it's 50+ MP, it'll be 4.3 FPS or less.

Any update to the 60D in next 6months?

I believe the 7D was being sold for 999.99 a few days ago. You can get a used one or a refurb from Canons Customer Loyaltry program for under 1000 bucks.
If the AF of the 60D doesn't bother you, then i'd get a used 5D Classic for around $650 bucks or a used 5DII for hopefully $1200. I greatly prefer FF to crop, but then, you'll need new lenses as well.

50mm lens. I Need advice!!

bdunbar79 said:
I'm definitely a fan of the 50L if you like f/1.2 to f/2. I've never seen better color rendition and sharpness at those wide of apertures. Unfortunately I don't shoot at 50mm that wide, so I couldn't make use of the lens. I like your photos!

I Love this Lens! the 50mm is perfect for what I shoot and the f/1.2 is just awesome!!

But I feel like my 7D is holding back the potential of the lens.

and thanks! I'm glad you like my pics. :) I've only been shooting for like a couple of months! lol

Canon EOS 7D Mark II Information [CR1]

Just sold my 7D for a decent price. ;D
Now I can recharge my credit card and wait to see what's around the CES corner.
Hopefully something with better low ISO performance and equal or even better AF and, dare I wish for it, to be affordable? Would be nice to hang an improvement on the end of my 100-400mm. I can wait until summer on that.

My 5D2 should find a new place to live too. gonna take a bath on that one. ???
Possibly followed by my love-it-hate-it 70-200mm f/2.8 L IS II if I don't stay in the Canon semi-pro body camp. :-\

Video Autofocus on Canon 6D?

I own a T4i and I just checked out the 6D at my local store, and it seems like AF during live view is just as fast if not faster than with my T4i. I couldn't figure out how to do AF while recording (probably some custom function for that ), but I was pretty impressed.

I know it doesn't have a hybrid CMOS sensor but I thought it was pretty damn good.

Panorama Thread

edit: The image I posted here seems to have vanished from flickr. I must have deleted it by accident while cleaning some old images out.

I found canonrumors while researching a DSLR purchase in the distant future. Lots of great information I'll put to good use when I get my first DSLR.

In the mean time, I thought a thread for panoramas of civilization would be nice. This is the local grocery store, wrapped in fog on a damp Christmas day:

The sensor size seems to be a point of concern for many but as you noted in an earlier post there are some very good examples of shallow DOF from this camera.
What is of the greatest interest to me is the DR available from the sensor.

I am looking forward to that happy day when yours is truly here.

I am interested in your GoPro experience as you use it.

The DOF did look very shallow, especially at F/1.4. I think the fact that the lens retains it's minimum focusing distance allows you to really turn the background into mush. I didn't really get a chance to push it to the limit in terms of dynamic range, but from what I saw it's far better than DSLR's (as expected). 13 stops at that price range is just unheard of, I think you'll be pleased with it either way.

As for the GoPro Hero 3, it's amazing from what I can tell. Being able to control it from your phone is just awesome, you can change from 2.7Kcine/24fps to 720p/120fps in a few seconds instead of hitting those buttons over and over. The IQ is noticeably better, low-light is better, image is sharper, and the "Protune" feature is nice (gives you a more washed out image for color-grading and manual white balance control). I think it's absolutely worth the upgrade from the Hero 1 and even the Hero 2. I'd feel much better about intercutting footage from it with DSLR footage.

Also, the guys at the shop seemed super pumped about the Sony F5 (which looks amazing of course but is considerably more expensive). I can't wait to check that thing out, 4K, 2K Raw with high framerates, etc. I think Sony is going to kill it with those things.

Yet another second body/backup camera question

I have a 5D3 and just sold my 1D3 and 5D2....

5D2 was a good camera...

my own feeling is that two 5d3s make sense.....

if any of your future (or current) lenses are zooms ... you get better micro adjust
the 5D3 wide AND TELE micro adjust (2 points) was a good improvement over 5D2...

also if you have the same cameras you will refine your understanding of ops/function together
...faster ... sharing settings /questions - IMO

finally when one camera seems to have an issue...the two can be compared..
much like working on a stereo amplifier... you have a working reference to compare to.. L or R channel

I dont see 6D as viable... the focus systems are too different ... 5D3 versus 6D (not strong enough)

maybe 2 ... $2800 purchases are steep...but if it is a 'near option' ...
then just stretch into it (...not having to pay myself ......sorry)

or WAIT for a new Canon 2013 body....but a long wait maybe...


the 1Dx is to far away to get 5D3/1Dx combo.... I am sure

just my opinion...not having to live with your budget....

Samyang 24mm tilt and shift

Drizzt321 said:
Exciting! Now if it's IQ is close to the Canon and it's priced around $1K or less, and we have a winner on our hands. If it's $600, it'd be really, really hard to resist buying it on the spot.

recent rumor price from russian site implies a price of a bit over $1000 on intro.
if if really performs, I'll be all over it even at intro price.

Around $1K is great if it performs, I'll just have to hold off a bit on buying it. Priorities you know :( Why can't I just have enough money to buy every darn lens that I want? It's only going to be a few 10's of thousands of dollars. Come on, it isn't that much? Just one good lotto ticket would do.

TS-E 24mm II + 2x Mk III Extender

Higher mag than the native lens - up to 7x with the 1.4x TC and 10x with the 2x TC.
I've never owned a tilt-shift lens but did you mind explaining how the magnification increases that much rather than just 1.4 or 2x?

We were talking about the MP - E65,in regards to other lenses you could use extenders below 135L
Thanks my bad, I'd missed a MP - E65 had come into the equation and was wondering how an extender could increase the magnification of a TS lens 7 or 10x relative to original magnification.

Yongnuo YN560 II

Sunny Alan said:
I recently bought a Yongnuo YN560 II flash for my 5d2.
The flash is firing individually on test, but not when connected.

1. Is there any setting in camera ? (On the menu when trying to set the 'Flash function settings' it says "This menu cannot be displayed. Incompatible flash or flash's power is turned off"

2. What will be the problem? Please help...

The flash is not compatible to ETTL and it can be used with manual settings or as a slave.

Do other lenses compete with the "look" of L primes?

Problem is that you are lumping all Canon L lenses into a certain class. Like everything, some are better than others. Some non-L's are better than older L's, etc. The comparison you showed does not suprise me with the 35L. The 35L I think is one of Canon's "weaker" L primes, whereas the 24L, 85L, 135L, and 200L are very strong. (35L and 50L I don't particularly care for). To answer your question regarding the 85L vs. 85 f/1.8 at let's say, f/2: Yes, I think the 85L II does look better overall. With the 50L and 50 f/1.4, I could never tell the difference in anything between these two lenses at f/2.
Hmm, coming from one of the guys I really respects on this forum I will now look at my 35L im a different way from now on. :D Seriously, about the 35L, if you disregard the last few weeks with people suddenly considering the new Sigma 35 as a gift from god the only real criticism Ive read about that lens is the lack of weather sealing. I love that lens, it's my only prime and Ive taken some magic pictures with it. On the other hand, photography is not what puts food on the table in my house.

No, haha, I don't mean the 35L is a bad lens at all. It is a great lens. Look at it compared to Canon's 35 f/2 lens. It is much better. So with regards to the 35L, it certainly fits the question of whether the L lens has a different look. It certainly does! I was just comparing to the other L primes, which is stiff competition I agree.

Phew, thanks man. Now I can put it back on and start using it again :P

Your first problem here is that you're listening to what I say :).

Well I'll actually continue with that I'm afraid. Without a guiding light I would simply be lost. ;D

World's First EOS-1D C Motion Image Shoot

I feel like what they are talking about is a mirrorless camera that can crank out 24+ frames per second.
When you get to a certain frame rate without a buffer holding you back, it's easier to call it a video camera.
The lines are definitely blurred between the two styles of image capturing.
Seeing as Canon has the tech to do this, I would almost prefer a camera that is pushed to its buffer that can get many more than 24 frames per second, but for a significantly shorter period of time.

Hell, I'd imagine we won't need to make this tradeoff for too much longer anyhow.

The IS of Canon 70-300l

I agree that the $100+ for the Canon collar is not worth it. I use the lens handhold most of the time. I did get a Fotodiox collar for the lens (around $40 IIRC) which works fine. It is maybe a little tight when you loosen it to turn the camera from portrait to landscape orientation, but it works. TDP mentioned that the original collar made metal-on-metal scratch sounds, so I don't think the original is any better in this respect.

Need a little help with 300mm 2.8 IS that I just bought used...

PackLight said:
curtisnull said:
None of my IS lenses including my 300/2.8L IS II make any audible noise with the IS on. Of course, it would't surprise me if some people on this board are listening to their IS lenses with a stethoscope.

All the more reason for us to upgrade our Version I's, we can get rid of the stethoscope and the whirly noises.

No no no. You got his post all wrong. What he means is that he "wins."

Patent: Integrated Lens for an APS-C Compact Camera?

Amazon is selling the G1X at $629 and the RX100 at $648

Anyway, I took quite a few thousand photos with the G1X and loved all the images I got from it. My main camera is the 5D2 and I have a few Canon glass. It does not make sense for me to invest in another mirorrless lens system for my leisure camera.

The G1X is a great one lens solution for me. I do hope Canon would address the macro distance and short battery life issues in the next version though.

Nikon AI-S primes or two good zooms?

Dump those Nikon lenses and go Canon asap. I was the same as you when I started shooting DSLR video - had a collection of Nikon Primes that I adapted to Canon, and used full manual the whole time.

It was a good way to start, but once I upgraded to Canon glass (& 3rd party Canon mount glass) I was so much happier. I could use AF for stills when I wanted to, I could see my aperture value on the rear and top LCD screens & I could adjust shutter speed or ISO and Aperture simultaneously with one hand. Much easier and nicer to use.

If you do go for the 2.8 zooms, then consider adding a 50mm 1.4 for those times you really want to shoot in the dark (like wedding receptions). I use 2.8 zooms for 90% of what I shoot, and love it.
