| Canon 70D with 300mm f2.8 IS |
I purchased my first DSLR back in 2003,when most were
still shooting film and digital photography was just beginning its'
rapid rise to the forefront. That camera was a Canon 10D, a 6.3
megapixel camera, which if I recall correctly had an ISO range of
100-1600. I stuck with this range of camera for several years, but I
didn't buy each model that came out. I passed on the 20D and 50D, but
used both the 30D and 40D extensively. Canon changed things with the
introduction of the 7D in 2009. This camera had a more professional
feel and features than the 50D. With the advent of the 60D it became
clear that Canon had in effect replaced the 10D-50D type camera with two
different types--a higher end one (the 7D) and one that didn't have as
many features or quite the professional feel, but was a distinct notch
above the Rebel line in this aspect. With that being said, the 60D was
and is a great APS-C sensor camera. Perhaps the greatest loss was
micro-adjustment which was introduced in the 50D, included in the 7D,
but not in the 60D.
In 2011 my main camera was the 7D,
which was usually mounted on one of the big telephotos with the 40D
being used with the 70-200mm, etc. so that one could cover a variety of
situations without changing lenses. Since I am primarily a video
shooter, in the spring I decided to replace the 40D with another Canon
that shot video. A flip-out LCD is a decided plus for video so I was
going to get a 60D, but then I found that the recently introduced T3i
(600D) had a 3x crop mode that made extreme long range wildlife video
recording possible. Since Canon had discontinued the XL-H1 type of
camcorder that excelled at this, I was on the lookout for a technology
that would give me the long range ability so there was no difficulty in
selecting the T3i over the 60D. The 60D is a more solid feeling camera
and I prefer it for still photography, but since video was to be my
primary use, there was no regrets.
I thought that Canon
would improve on the 3xcrop or 3x-10x digital zoom principle and
incorporate it in most if not all future models, but I was disappointed
to find it was not in the 5D MK III or either of the two Rebel models
that followed, the T4i and the T5i. Although they did introduce auto
focus in the T4i this was not of interest to me without the 3X crop
mode.
I got the 5D MK III in May of 2012 with its'
primaryuse to be as a still camera. I found it had the best video
quality of any of the Canon DSLRs I had tried so far, but it was sadly
lacking in reach for long range work on whitetail deer, birds, etc. In
the meantime I had read many positive reviews of the Panasonic GH2,
which was reported to have better video quality than the 7D, 60D, and
the Canon Rebels. I found this to be the case and used a GH2 for long
range video work from July 2012 until late January of 2013 when I got
the Panasonic GH3. This camera had even better quality than the GH2.
Another plus for the Panasonics is that they have decent autofocus in
video mode when lenses such as the 14-140mm Lumix or 100-300mm Lumix are
used. With that being said, I am not sure they have better video
quality than the 5D MK III. They are a definite cut above the other
Canon models we have mentioned in this respect; however. but in my
opinion the Canons win hands down as better choices for still
photography..

It was certain that I would try a 70D at some point
when it was announced that it had "advanced movie digital zoom". This
turned out to be a 3X-10X digital zoom like that on the T3i, although
with the T3i they played up the term, "3X crop mode"instead. Digital
zoom has always left a bad taste in my mouth in traditional camcorders,
etc., but this is somewhat different as at least on the T3i at 3x it is
supposedly reading the central portion of the sensor to record a full HD
1920X1080 video file. I am told that in actuality it is not quite
full HD and is upscaled a bit, but it is still close enough that it does
give very acceptable video. Based on limited experience comparing the
two cameras so far it seems that the 70D digital zoom is the same as
that in the T3i and is very usuable at 3X so it is likely actually the
3X crop at that point. On both cameras once you go past 3X you are into
the same negative that has always existed with true digital zoom in that
you are enlarging pixels and the image rapidly downgrades as the power
is increased so I do not think it is usable for serious work past 3X. I
do think the 70D video quality is a bit better than that of the T3i,
but there is not a tremendous difference at the lower ISOs. It seems
like it gives significantly better performance at the higher ISO
settings, but I am not certain of this yet. I will post no video clips
today, but hope to do so after I do more testing.

Perhaps the biggest news about the camera is the use
of a "revolutionary autofocus technology that unlocks the potential of
Live View: Dual Pixel CMOS AF. This game-changing technology allows the
EOS 70D to capture video in Live View with smooth and precise autofocus
similar to that of a camcorder, complete with the superb image quality
that is a hallmark of EOS cameras. Additionally, Dual Pixel CMOS AF
provides fast and accurate autofocus during Live View still image
capture, enabling you to fully benefit from the freedom of angle allowed
by the Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II.
Compositional options are now nearly limitless with the two real-world
choices of Live View and viewfinder shooting" as Canon describes it on
the
Canon USA Website.

In my limited experience it does seem that they have
taken the use of live view for still photography to a new level. Gone
are the days of lengthy hunting for focus in live view mode. I like to
shoot video with the camera on a tripod and about waist level or
slightly above with the LCD tilted for easy viewing in that position.
Now taking stills is as simple as switching from video mode to your
favorite still mode and pressing the release button. Focus is rapid and
accurate. You could actually remain in video mode and capture the
still for even less hassle, but I use different the Standard picture
profile for stills and Neutral profile for video so I do like to change
the mode button if possible. In addition the camera focuses very well
in video mode and compares favorably to the Panasonic cameras. It will
take more use to develop a final opinion. One minus is that the Canon
cannot use the new autofocus technology in the digital zoom mode but
reverts to the old method, which will not track motion. Regardless of
this, it still seems to focus reasonably well and will remain on the
subject without hunting about until one presses the shutter release to
refocus it. Once focus is set you can press the movie button (it will
not cause the camera to refocus ) and you can film in good focus until
the subject moves and then you can either stop the camera and press the
shutter button to auto focus or you can try to adjust focus manually
while the camera is running, which seems to work reasonably well.
While
autofocus in video mode brings a significant gain in ease of use it
does create problems with getting good sound. Only Canon STM lenses are
silent focusing. At this point only a few are made and none are large
telephotos or L lenses, so the vast majority of Canon lenses make a
noise while focusing that is easily picked up by the internal mike or
shotgun mikes mounted in the accessory shoe. To date I have tried the
camera with the 70-200mm f2.8 II L, 24-105mmf4L, and the 500mmf4 IS L.
The 70-200mm is the quietest with the 24-105mm running a close second.
The 500mm f4 is very noisy, but still focuses quite well. The bottom
line is one needs to get the mike off of the camera for best results in
situations where audio quality is critical.
Most
readers are likely more interested in how it performs as a still camera
so I am posting a few stills. I realize that perhaps I should post
comparison shots between different camera models, etc., but at present
time constraints prevent me from going into it this deeply and it can be
hard to judge quality differences in internet photos and video anyway
so here are some photos to give you a general idea of what to expect
with this camera.

All in all the 70D seems to perform quite well in
good light. The 5D MK III seems to get a higher percentage of
photographs in perfect focus, but the 70D does quite well. I think that
those that are used to the 7D and the 60D will find the camera very
acceptable, but I doubt they will notice a terrific improvement in still
image quality, although the inclusion of micro-adjustment should give
it a sharpness advantage over the 60D in some instances. Of course
there should be some gain in quality because of the 20.2 effective
megapixel sensor vs the 18 effective megapixels of the 60D and 7D. In
addition there may be some gain in quality due to the DIGIC 5 processor
of the 70D v.s. the DIGIC 4 of the 60D, but that is beyond the scope of
this article.
The shot below was taken early in the
morning and although I could have gotten away with using a lower ISO by
going to a lower shutter speed, I wanted to get a general idea of how
the camera performed at ISO 1600. The image is also cropped a
significant amount. Noise is noticeable on a large monitor.

When using the noise reduction tools in Photoshop,
one must choose to have the image as sharp as possible, reduce the noise
as much as possible, or find an acceptable compromise between noise and
sharpness. The image above was the best I could do with noise reduced
somewhat and the image being somewhat soft in the fine details. Whether right or wrong, I turn all in-camera noise reduction off and rely on Photoshop for noise reduction processing.
The
bottom line is that based on my limited experience with the 70D I think
it is better at handling high ISO settings than the 7D or the T3i, but I
never used the 60D so have no opinion on that. It does not do as well
as the 5D MK III at high ISOs, but that is to be expected. Over a
period of time a much clearer opinion of its' capabilities will emerge,
but for now it does seem like a good camera for the price range. It will
be interesting to experiment and compare it against the other cameras
that I use. At present my favorite still camera is the 5D MK III and
the video favorite is the GH3. It will be interesting to see if that is
still so a month from now.
