| Canon EOS 1D Mark IV 16.1 MP CMOS Digital SLR Camera with 3-Inch LCD and 1080p HD Video |
I have never been concerned about the 10.1 MP size of the Mark III having had many of my images blown up to 6x8 feet posters used on the outside of theatres and large shots used in four color programs. I had several concerns with the Mark III which I had hoped would be addressed in its successor, the Mark IV:
1. A higher ISO range with equal or less noise
2. The ability for the focus point to switch when changing from landscape to portrait orientation. - Although the Custom Function allows one to change the rear wheel to adjust the focus point, I prefer to use that dial to adjust for exposure. Having to switch in a very fast paced situation caused me to miss some great shots.
3. More selection of focus points for manual focus point adjustment
Other than those three wishes, I was happy with my Mark III. In all three cases, the Mark IV met my wishes. I have done a comparison in low light, low contrast situations with both Marks at ISO 6400, which for the Mark III was considered H1. As such, adjusting the ISO from 3200 to 6400 was not possible in 1/3 stop increments. More on that later. In the comparison, the Mark IV handily beats the Mark III in terms of detail and noise at ISO 6400. Much more detail is visible which has something to do with a higher MP count, but at 100% crops, there is a marked difference. The noise on the Mark IV is less and of a different quality than the Mark III, more film like than digital.
During performances I had only used ISO 6400 in conditions which made lower settings impossible. I have always thought that a noisy shot is much better than one that is blurred beyond usage. My clients agree. One of my favorite lenses to use while shooting on stage as well as from the house is the EF 24-105mm f4.0 IS L. The focal range on a 1.3 crop sensor is just PERFECT, but the slowness of the f4.0 kept me from utilizing that lens with the Mark III unless lighting was sufficient. This will all change with the Mark IV as ISO 6400 is just fine using a f4.0 lens in my conditions.
Keep in mind that everyone needs to decide how a camera is to be used, under what conditions and it is naive to think that an investment in current glass won't influence a decision to stay or leave any brand of camera. I am heavily invested in Canon glass and all of them are L series lenses. I find that the color and sharpness of L series lenses are worth the investment, especially since I purchase most of them on the used market. There are folks who love to go back and forth on brand, pixel snooping, stats, etc. in hopes of proving themselves 'right.' I am NOT one of those people. To me a mediocre/poor/boring image is the same whether you take it with film, a full frame DSLR or medium format camera. (BTW, I'm not sure why 35mm is considered FF anyway. I consider 2.25x2.25 my idea of full frame!) My personal opinion is those who often argue ad naseum about camera stats take the lousy or boring pictures anyway.
I have NOT been able to use the camera in high movement, low light performance photography as I write this. My first opportunity for that comes this weekend. It will also be the first time I have the chance to shoot with two separate cameras with different lenses attached. That will give me a good, but not scientific comparison of the cameras, but more important for me is whether keeping both is worth the effort. I will decide if the Mark III gets a new home or not.
My advice is to base your hard earned purchasing dollars on what is right for your situation. My Mark III has performed well in the past and I'm confident after some of my own testing that the Mark IV is even better. Time will tell and as I gain more experience shooting with this new tool, I may add my insights here in the future. Best of luck with your own shooting!
Today I had my first opportunity to shoot in low light with the Mark IV. Although it was NOT as high movement/low light as I am accustomed, it was a very good initial test. I shot a choral group with musicians, so movement was nice and slow, except for the conductor. It was also the first time I was able to use two camera bodies without switching lenses. On the Mark III, I used a EF 70-200mm f2.8 L IS and on the Mark IV, I utilized the EF 24-105 f4.0 L IS. This focal range allowed me to cover all that was necessary. Obviously I used the f4.0 on the Mark IV because of its higher ISO range and noise performance.
I want to say that it will take some adjustments moving to the Mark IV. As I reviewed some images from other photographers using the Mark IV prior to receiving my own camera I had no idea what conditions the photographer's lighting conditions presented. I can say that because of the new sensor and ISO performance, it makes scenes appear MUCH more well lit than I experience with my human eye. In the past I have run -1/3 to -2/3 EV when using my Mark III to prevent blow out in highlights even using Highlight Tone Priority. Tonight I set both cameras on 0 EV to compare. The Mark IV presents a brighter image, about 1/3 stop brighter than the Mark III.
Because this was not a paid gig, I took more chances with the imagery than had it been for pay. I found that in camera Noise reduction of 1 Low suits my taste much better than -0 Standard in the Custom Settings function. There is a different quality to the noise produced at Standard over Low. I prefer Canon's Low setting, but your preference may differ. The highest I found it necessary to set the ISO tonight was at 10,000. Upon examining the images on my monitor, there is the most noise in the subtle shadow areas around the subject's chin and lower neck. This is normal in my experience along with noise in large solid color backgrounds. But the noise at 10,000 is easily much better than the Mark III at ISO 6400. In addition the detail that remains at 10,000 eclipses the detail, or lack of detail in the Mark III at 6400. I measure my detail in the hairline wrinkles around the eyes and in the forehead of my subjects. The Mark IV sustained those details where the Mark III at 2/3 stops lower ISO did not.
Also the noise produced by the Mark IV is more chroma than luminance. In my workflow, chroma noise is MUCH easier to reduce than luminance noise. The dynamic range of the Mark IV in terms of color is FAR superior to the Mark III, but I attribute this to a new sensor and new processors. Camera bodies are really just like computers, as soon as they come out they immediately begin to become obsolete. The color and white balance are MUCH better than my Mark III. It still takes some adjustment, but much less than the III.
The automatic focus point association between landscape and portrait is a God send! Also the Mark IV takes advantage of UDMA card speed. I purchased a 32gb Sandisk Extreme CF card for the Mark IV and it's rated at 60mb per second. In shooting RAW burst, the ability of the Mark IV to write to the card after the buffer is full is easily three times as fast as the Mark III, but to be fair the III doesn't have UDMA capability.
So far so good. I plan to keep my Mark III simply because shooting with two cameras with different focal length lenses is the only way to go for my work. At some point I will replace the Mark III with another IV, but that will take time and a few more clients. It will be interesting to see how the images look at high ISO in large format, which much of my work is used as with clients. I'm happy with my choice so far and anticipate that more work in my normal venues will continue to show favorable results.
My issue is now how to build up my neck to support two 1D bodies with a 70-200 on one and a 24-105 on the other! When I use my 28-70 in place of the 24-105 it's going to be a real pain!
Tonight I had my first opportunity to shoot a theatrical performance with the IV. I can only say that Auto ISO along with AI Servo will change how I shoot theatre. The settings I used tonight were Highlight Priority On, AI Servo, single shot, Auto ISO, ISO range L to 12800. The lenses I used tonight were the EF 24-105 f4 L IS and the EF 70-200 f2.8 L IS. Anticipation is such a major part of theatrical shooting, waiting for just the right expression, gesture and moment. I was able to capture images tonight with a clarity that I have not experienced with my Mark III. Auto ISO constrained within the parameters I wanted left me free to concentrate entirely on capturing the moment while retaining a speed proportionate to the focal length. By freeing me up from keeping an eye on the shutter speed, which was set by the Auto ISO, I was able to compose my shots more accurately. Using AI Servo for my focusing also allowed me to follow the subject and keep them in focus just before pressing the shutter. I watched and anticipated their expressions like never before.
The ISO varied between a low of 800 in very good stage lighting to a high of 12800 in those scenes where it was too dark for me to know the actor's expression. I ran an EV value between -.33 to -1.0 to compensate for harsh spot lighting, so common in stage work. In those cases where the shot was very dark, where the actor's face was shaded in a very dark manner, ISO 12800's noise is very visible, but not to the point where a noise processor will bring the image back to usefulness. In those cases where light is medium, I will NOT have to use noise reduction post processing for printed images in large format.
So with my last entry I will simply say that I am pleased to have made an investment in the new Mark IV. It surpasses my Mark III in a way that will now allow me to press the limits of my ability to capture even more compelling imagery. And in my work, an image that moves the viewer is one I'm proud to produce, regardless of the equipment. The Mark IV will certainly push my own skill limits in a way I'm happy to undertake. It's a tool that will help expand the level of my own creative process.
Best of luck to all of you in whatever you decide to purchase and shoot. It's time for me to get back to work.
I'm not sure how many of you who own the Mark IV have upgraded your firmware to 1.0.6, but if you haven't, I would recommend the update. Although Canon has not released specifics about the update I can tell you that from personal experience, it helps to track objects that pause for 1-2 seconds before moving. Prior to the update I noticed that when a performer paused, the AI Servo mode hunted a bit attempting to stay on the same trajectory as the subject's last known movement. With 1.0.6, that pause causes the camera to hunt much less than before. I have now had the chance to use the Mark IV in two live theatrical performances, one publicity shoot, low light street shooting and one wedding. (My gawd I hate it when I get coerced into shooting the occasional wedding, but when my regular clients 'ask' what is a guy to do?) and the image quality along with high ISO performance is remarkable. In real world applications ISO up to 10000 is very usable for print in large format.
In addition, having studied Canon's guide for AI Servo and High ISO usage is necessary in order to customize the camera for specific applications.
Having used this rig for quite some time now in various low light/high movement situations I wanted to comment that I have avoided the use of the higher range of ISO, specifically H1, 2 and 3. In those cases where I wished to reduce the noise levels in post processing taken at ISO 12800 I had used Noise Ninja with good results. I recently purchased Adobe's new Photoshop CS5 and decided to process some images taken at H1 and H2 through their Camera RAW noise reduction scheme.
Obviously the quality of light has a large bearing on the amount of noise in any high ISO image. But I can say that using the new Camera RAW noise reduction in CS5 now allows me to use both H1 and H2 ISO on many more 'non emergency' situations. In the past Noise Ninja did not yield acceptable results at H1 or 2, blurring the detail beyond my acceptance level. CS5 removes that obstacle and I now find that shots taken at H1 (ISO 25600) are VERY useful both in print and on the web. H2 at 51200 are also useful when run through the noise reduction program. Yes, there is noise and if one is expecting a very low level of noise I would recommend you NOT venture into those ranges. But if like me you are sometimes REQUIRED to get a shot that captures the moment in more than acceptable fashion, I highly recommend the use of CS5's Camera RAW noise reduction with the Mark IV. It is a combination that has allowed me to capture and produce imagery like never before.
