For those of you who have an Ipad.... Canon Singapore has put out a very interesting (and free) app called CanonSGLens, you can searh for it on the apple store...

It gives lens specs, drawings, MTF charts, allows comparisons, has a FOV simulator, depth of field simulator and calculator, etc etc....

It is mostly a camcorders. Why it can't be a DSLR?
The new rumor mentioned about EOS 70D, with 3" flip screen (some people take it as 3.0fps as a mistake), if there's on chip phase detection AF, with the flip screen, it will be better for shot over head. It is what 650D/T4i has did now, but it is a little of low end, and not strong enough.
It is also said that the sensor is the same between 7D2 and 70D. Maybe it's idea of:
7D2 prefers the users of extreme, who are mostly using OVFs. Just thinking of 6D, 5D3 or higher. Some people hoped 6D should have a flip screen, as 60D.
70D prefers the users of mainstream, who uses screen more often, and with the help of flip screen, LV or video is more easier. It would take a position of video DLSR for APS-C format. 1D C is alternative 1D X in FF, there should be an alternative version video DLSR in APS-C.

My real-world review of the Canon 6D. It's fairly short but contains a few pictures mostly illustrating it's excellent noise characteristics at high-iso. It's especially useful for wedding photographers but anyone considering buying it or wanting a comparison with the 5D Mark III should find it useful.

I have heard many people say that the Nikon DSLRs have no cross-type AF point on two sides, the points only lie in the middle/central area. The 51-point system (15 cross-type) of Nikon, named after 3500, can be date back to the year of 2007, begins first of D3. The AF system of D4 right now is the improved version. Besides, the 39-point system (9 cross-type), 4800, also has the fatal weakness: no cross-type point on two sides. However, for Canon, the ellipse 45-point AF system, which can be date back to film times, and which reaches the strongest condition: 39 cross-type points and 6 line-type points on EOS-1D MK IV, has been abandoned by Canon, and replaced by the newly 61-point AF system.
Why should I emphasize that the 45-point system on 1D4 is 39 cross-type and 6 line-type? Because Canon had the assist points before. 5D2 has 9 AF points, but some people say it has 9+6, the 6 is assist points. When it is in 1D MK3 or 1Ds MK3, the ellipse 45-point AF also has assist points. It has 19 cross-type AF points and 26 line-type assist points (cannot be selected by users). Maybe the 19-point system on EOS 7D comes from the 1D MK3. When it comes into 1D MK4, more cross-type points and no more assist point. Maybe it can be made into all 45 cross-type points and no line-type point, for it is on purpose by Canon why it didn’t do that. It is F5.6 line-type plus F2.8 line-type, when it is F2.8, it comes into cross-type. Besides, the center point can do cross-type AF under F4.0, and AF under F8.0. In some particular situation, all the 39 cross-type points can do cross-type AF under F4.0. In the opinion of now on, it may be a little older, for it has no dual cross-type point, the newly 61-point AF has 5 dual cross-type AF points. It could have the dual cross-type AF point, for EOS 7D before it already has. Why should it have the dual cross-type AF point, what is the purpose of it?
The dual cross-type AF point on EOS 7D, is designed for focus accurately. But there is only one on 7D. Theoretically, when using F2.8 lenses, it is the only one point which can do AF accurately. Though it makes F2.8 lenses essential to have cross-type AF points available when using the EOS body of 1D MK4, in final using it, almost every point can been used for accurate focusing. The mainly purpose of dual cross-type AF point is for high precision focusing, but it have reached the goal by cross-type AF point on 1D MK4, so making the dual cross-type on 1D MK4 may be redundant. However, we have to admit that it makes F2.8 lenses, or at least F4.0 lenses essential, or we have to accept the fact that there will be no cross-type AF points.
So, the 61-point AF that contains 5 dual cross-type points has appeared, and applied on EOS-1D X, which is the first time for 1 series bodies to have dual cross-type AF point. And the number of dual cross-type point increased to 5 from 1. At first I didn’t got it that why it is vertical 5 points in central, and why it is not cross-type 5 points, or matrix 9 points. In this time, Canon has added F4.0 sensor, and it comes into 2 lines in each sides, 4 lines in total. When it comes in F4.0, it will have cross-type points in two sides. (PS: much better than Nikon, it won’t have ever.) When using F2.8 lenses, I think it will also have better precision than F5.6 sensor.
However, when the 61-point AF meets the extreme-conditioning ellipse 45-point AF, degeneracy has emerged: number of the AF point which works under F2.8 and is more accurate has decreased to 5 from 39. The 20 points under F4.0 may work better under F2.8 than F5.6, and new technology may make it more accurate for non-F2.8 sensors. But in theory, at least the AF points work under F5.6 in 61-point AF, 61-5-20=36, they are not accurate enough in the situation when aperture is under F2.8. Regarding the future, no matter of the speed or ability of focusing, or the accuracy of final shot, the dual cross-type AF point has more advantage than the normal cross-type one.
I have heard this saying: if choosing between 1D MK4 and 1D X, someone will still choose the former, for it is more mature. There has been several firmwares for 1D X, and solved many bugs. If we prefer the AF point which is dedicated under F2.8, it is surely degeneracy. Besides, the X-sync of 1D X has decreased to 1/250s from 1/300s of the APS-H format 1D MK4. I don’t know whether it should have an X-sync of 1/300s for APS-C, for APS-H already has. Maybe it is the last one for 1D MK4 that has APS-H format and ellipse 45-point AF in 1-series EOS bodies, but it may be back somewhere and somehow. It is hoped that EOS 6D would use the 19-point AF of 7D, but it uses the 11-point AF mod by the one in 5D2. EOS 7D was the first one uses 63-zone metering system who is not 1-series body. 45-point AF is still 1-series exclusive, the situation may change now. 1D X and 5D MK3 have used the new 61-point AF, which makes the 45-point AF a high-end accessory no more. The rumor of EOS 7D MK II has said that the AF may not be the 61-point one, but it will not get poorer performance than using 61-point one. In the tradition of 7D and 5D2, the sensor smaller, mechanical performance better. 5D3 has FF and high performance, so 7D2 should has an APS-C sensor and ultra high performance. Usually, more AF points, better. 45-point AF has lesser point than 61-point has. The prediction of Impress Japan has listed in Japanese (some Japanese font is Chinese ;D ) with the saying of 7D MK2 has the AF point of more than 40, it should be the improved version of ellipse 45-point AF with some experiment technology. In my opinion, Canon goes on an experiment of dual cross-type AF point on the 45-point AF, which has more than ever. How about the 45-point AF making of 19 dual cross-type points and 26 cross-type points? Haha. And when it is mature, makes 61-point AF with more dual cross-type AF points. Why EOS 6D still has no dual cross-type AF point? Because the experiment on 6D is -3EV light focusing.
In future, when the number of AF point works under F2.8 is more enough, it could have a selection of “only using high precision AF points” when using F2.8 lenses, just like “only show cross-type AF points” in 61-point AF. Quote and modify a saying: Canon don’t want users having a DSLR that has not cross-type AF points enough when using, and has no F2.8 sensor for high precision focusing when using F2.8 lenses; Canon is working on to make it reach the altitude of usable for amount and distribution of the F2.8-sensitive AF points. PS: how about the altitude of distribution of Nikon’s cross-type AF points?
The type of sensors, line or cross or dual cross, the precision of sensors, F5.6 or F4.0 or F2.8, the combination of the two is surely an art.

I picked up a 1D Mark IIN a few days ago, it's my first time with a 1-Series body. I'm moving from a 40D/60D set up to a 1D IIN/40D set up as I'm shooting mainly sports and events. The previous owner was a press photographer who used the camera for years and looked after it, she never had a problem with it.

I've noticed that there's a slight hesitation before it attempts to find focus and it's noticeably slower than my 40D, it doesn't feel quite as snappy. I've tested it on a Sigma 24-60mm F/2.8 and a Canon 70-200mm F/2.8L and the results are the same. The tests are using only the centre AF point. The 1D hunts a fair bit more in lower light than the 40D but I put that down to the age difference between the two. Could the hesitation problem due to the age as well? I wiped down the lens contacts but that didn't make a difference.

I'm considering sending it in to the local Canon service centre here in Dublin, but would just like some other opinions before I do so.

I have a canon 550d rebel and was considering the "jump" to FF.

The Canon 6d is in my budget. However the Nikon D800 is available (refurb) for $2,300.

I ask myself - why spend almost the same on the inferior 6d ? Why does canon seem to give less and charge more ?

36.5 gigs 2002 through 2012... at the moment...though I feel like whittling down even more. Actually quite a lot of TIFF files(star trails/etc) in that making it larger than it really is imagewise.

I always wonder how many others are like me out there and delete like a madman, just to keep things in check as far as total images kept over the years. If I don't whittle often and delete away, I end up feeling like I don't even know what all I have and can't keep a grasp on that. Figured it might be interesting to see some of the total image file size out there. As in whatever you got that you keep and well back-up.

I'm sure for the wedding photographers and portrait business folks out there, it's a different deal and huge just for the customer's sake. Still probably interesting to hear.

Since 2002 I've had a Sony F707, 5 rebels and 2 5D II's and really actually shoot quite a bit. Often stuff that's just not repeatable later. I think many take the "logical" route of "it's safer to save and not delete and storage is cheap anyway". It is logical. Deleting takes courage lol. If I took that route and had been keeping everything, man I'd feel so so lost whenever I'd go to do anything with things. I get into a severe delete mode, just find something, anything to delete, to whittle the pile way way down. I do that with the collection, then later on I do it again to the same total collection. The earliest stuff gets so so whittled down. I'll stop and think to myself, what are you doing, then say screw it, just a photo, and delete...over and over lol. And of course half the time someone e-mails wanting to license an image, they pick one off the site that I never kept and I kick myself a little.

It's fun to sorta trip yourself out later realizing you can stick all the images you've kept the last 10 years on a single cheap flash card.

Hello,

I have Canon two speedlites (580EX II and 430EX II) and use the new Yongnuo YN-622C flash triggers with them. I was wanting to add to my flash guns and am considering the new Canon 600 EX-RT. My question is will the Yongnuo YN-622C (on camera) trigger the Canon 600 EX-RT (off camera) using the Canon's on board transceiver or would I have to put another Yongnuo 622 under it like I do for the other flashguns?

.
Anyone have any idea how many pictures they took in 2012?

I did a little research and learned I took about 30,000 pictures last year.

The files in my T2i indicate 26,000 with that camera. So, I'm guessing combining with the other cameras (S95, 1V, a Lumix, a Yashica, etc.) it's in the 30,000 range.

I don't think I need to do another of those 365 projects! Wore me out.

Just curious where other folks are with this.

"This is a dirty debayer with no black calibration, no offset correction and no processing on a special 21 stop DR Chart"

21 stops of DR at 6k resolution capable of doing 80fps. Methinks Canon is gonna be lowering the prices on their Cine line in the next year

Hello fellow 5D2 owners..

I have a pair of 5D2 bodies, and have both of them equipped with the BG-E6 vertical battery grips, and neither of them can be removed.. With both of them, the tightening/ loosening wheel spins freely.. and for the life of me, I can't remove the grips... I was wondering if anyone has had to send their 5D2 bodies in to CPS, USA, to have that fixed, and how much I was looking at to get those repaired..?

Much appreciated,

JP

Not sure my thread title makes much sense, but then again, if I new what the name of the feature is that I'm asking about, I could phrase it better. Here's what I'm curious about:

I don't yet own a DSLR (waiting to see if/when the 70D materializes). I currently use (and love) the Canon G12 for the photos I take. One thing that has been VERY helpful when I started using Manual Mode almost exclusively was that if I press the (*) button, it sets shutter and aperture to what it would be if in auto. I can then tweak it quickly from there using the manual dials.

This has been a great "crutch" for me as I develop my knowledge/skills. It's also really handy if the light suddenly changes (like going from shade to sunlight or front-lit to back-lit). I can just press the (*) button to get me close in an instant, rather than twirling the dials like crazy.

Is there a similar feature on Canon's DSLRs?

I've fiddled with my brother's T3i briefly, but when I press the same (*) button on his camera, it looks like it locks exposure or something...

If anyone has a quick answer on this, it'll save me a lot of reading various manuals for something I don't know the name of...

Thanks!

Guys,

I'm thinking about which lens I should get to shoot the matches of my amateur football team. I have the 5D Mark III and I would like to get the 70-200 2.8 II, but is it long enough? I mean if I stand behind the goal and only shoot the action in front of the goal it should be ok. But if I shoot other pictures from the sidelines it could be a bit short. On my old 600D I used the cheap 75-300 without IS and USM. Close pics were ok but far pics were not really usable. But the focal length on crop of 120-480 was very neat to have. So I'm thinking if the 70-200 2.8 II + 2X III could do the trick or if I should better opt for the 100-400? I will not wait for a new version because of many years of rumors for it to materialize and I do believe that the resale value of the existing version will not drop too much immediately.
The downsides of the 100-400 are obviously that it has 30mm less on the lower end and that it is not weather sealed as the 70-200 2.8 II and I would love to use it during some rainy matches too.

So what do you guys think I should do?

Cheers

Seb

May the New Year bring you fortune and good tidings!

5D2, 16-35 II, f/5.6 bulb mode (< 8 seconds) with cable release. Multi-shot pano for the neighborhood, then left the tripod's rotation unlocked, so that I could rotate it to catch fireworks. Matched them up to the pano via layers in CS6.

I have been doing some event work lately and have found the need for an 80-100mm "portrait" lens. I have a 5DIII 2x 5DII and 7D for bodies. I generally work with a 24-70 f/2.8 MKI on the 5DIII with a 600 EX RT and 70-200 f/2.8 IS MKI on the 5D II with a 2nd 600 EX RT and the 50 f/1.4 on the second 5dII. The issue I run into is I have a lot of crop work on the 50 f/1.4 to get that ideal portrait look.

I was thinking today (doing some wildlife work since the snow has been out in force) while shooting my 7D that the 50 would become an 80mm. I have rented 85 f/1.2's in the past and not liked them for one reason or another. So the question is: Using a 50mm f1.4 on a 7D will make it an 80mm, BUT how much light do I lose due to the crop factor? Has anyone done this with much success? Or should I just buy an 85 f/1.2 and learn to love it? I also would not be opposed if the 7D +50 idea works to buying a 50 f/1.2. I also own a 100 f/2.8 IS Macro but the DOF is a bit too shallow for what I want without stopping down to f/5.6

I've run accross a problem with my 1D X when shooting in manual (M) mode. If I have the camera set in Manual, the 2-second Self-timer enabled in Drive mode, and use Live View, the camera freezes up after taking a shot. I've verified that it does this with both the 17mm TSE and 8-15mm fisheye zoom (just happened to be the two lenses that I was using...). I have to turn the camera off and remove the battery to recover from it. I went back and tried the 2-second self-timer and live view with the AV mode and it worked OK so it seems to be specific to Manual mode. Can someone else with a 1D X confirm this behavior? I'm thinking it may be a firmware bug; not a problem with my specific camera.

Thanks...

So I don't understand the physics of lenses but if they can why couldn't they make a 28-400 2.8 lens. Even at 15,000 it would be worth it at the same price of All three combined.

don't shoot studio...it's action action action and both my cameras underexpose regularly by 1/2 to 3/4 stop....anybody with thoughts on this?

Well, I had been wanting a little more reach than my 70-200 f4L IS USM lens could give so I sold it and my EF-s 60mm macro (I really liked that little lens) and bought a new EF 70-300L lens from Adorama.

I replaced my 60mm macro with the EF 100mm USM (non IS, already had one but the ex wife got that one in the seperation...) I thought about getting the 100-400 but I really wanted a nice walk around zoom so the 70-300L seemed perfect.

I have spoken to people who have one and they love it. What are your experiances? Good? Bad?

I plan to take my 4yrs daughter to Mountain High in CA this Friday. This will be her 1st time touching and playing with snow. Our activities are: build a snow man, snow tubing, and walking around the town with hot chocolate drinks.

I'm thinking about 5D III + 24-70 II with RS-7 strap for this trip.

My concerns are:
1. Will my 5D III and 24-70 II survive the cold and wet from the snow?
2. Will this combo be little too big for snow tubing?

I have Canon S100, but I doubt I would be able to capture her sliding in the tube down the lanes or building a snow man with her cousins.

Your thoughts and advices are greatly appreciated

Thanks
Dylan

Thinking about buying 135mm F2. Anyone has 5D3 with 135mm F2 purchased in 2012? Can you share if your right, top, left focus points are accurate or not other than center focus point? Thank you.

Been contemplating if it's worth the upgrade, improved IQ and AF, to upgrade to a 1.4x or 2x Mk III Extender.

With spring training (baseball) just around the corner here in AZ, I want to be ready if I choose to upgrade. I will be using my 7D with my 70-200 2.8 II for outdoor games and once regular season starts (indoor games), I will use both my 7D and 5D3. I'm more interested in the 1.4x but am considering the 2.x Thanks

Since the Zoo Pics thread is getting quite long, I thought I would start a new one. Here is a shot from Christmas Day at Wildlife World Zoo and Aquarium in my state of Arizona. (One of the few zoos I know that is open on Christmas).
