| Sony NEX 7 with Sigma 30mm f2.8 lens |
I've had the Sony NEX 7 for six months now, during which I’ve
taken nearly 3,000 photos, and I’ve come to the conclusion that it’s the best camera
I’ve used for backpacking and hiking, both in terms of images and in handling. I
love using it and I love viewing the images. I had high expectations when I
bought it. These have been surpassed.
It’s been two years and nine months since I began a
changeover from DSLRs to smaller cameras with the Sony NEX 5. My thinking for
this I described in this
post. Basically I was looking for a smaller, lighter
alternative to a DSLR that would produce the same quality images and my
research suggested the NEX 5 was the best option. A year later I expressed my
thoughts about the NEX 5
here, where I said that much as I liked the
camera I was planning on replacing it with the even better NEX 5N or NEX 7 as
my main camera and using it as a back-up. I read several reviews – especially those
on
DPreview,
Luminous Landscape,
Steve Huff Photo and
DxOMark – and decided on
the NEX 7 as the better of the two for my photography, giving my first impressions
here. If you’re interested in
technical details, comparative studio shots and comparisons with other cameras
have a look at those reviews. Here I’m giving my personal impressions and
views.

Most of my photographs are landscape and outdoors ones taken
during hiking and backpacking trips, hence my desire for a small, lightweight
camera. At the same time I need images for publication in books and magazines
so high image quality is essential, which rules out compact cameras with their
tiny sensors as these just don’t produce good enough pictures. So until
mirrorless cameras with the same-size sensors as DSLRs appeared a few years ago
I used one of the lighter weight DSLRs. When I changed to the smaller NEX
system I wasn’t expecting better quality images than from my DSLR, just
equivalent ones. The advantages for me of a mirrorless camera were the low
weight and bulk. If these hadn’t been important I’d have stuck with a DSLR. The
weight saving is significant for a camera that will be carried all day however.
My old Canon 450D DSLR weighs 580 grams with battery, memory card and strap. The
Sony NEX 7 with the same accessories weighs 376 grams. Being much smaller it fits
into a smaller, lighter bag too and is less clumsy to carry.
For me the weight and size of the NEX 7 are enough to justify
changing from a DSLR on their own. However using the camera I have discovered
that there are many other advantages.

Using
I didn’t find the menu-based controls of the NEX 5 as much
of a hassle as many reviewers did but I had to admit that they weren’t very
intuitive and did take a little time and thought. I quickly got used to using
the screen rather than a viewfinder too, discovering that holding the camera
against my chest with the screen flipped up was at least as stable as holding
it to my eye. I didn’t really miss a viewfinder and I liked having the
histogram and exposure settings visible on the screen so I could adjust them
before taking a picture (I mostly use manual exposure and use the histogram as
a guide not what the camera says is the “correct” exposure). The NEX 7 however
has an electronic viewfinder (EVF) that shows all that information plus three
dials that control the shutter speed, aperture and ISO so all can be altered
with the camera to the eye. This is a lovely system that works really well. I
find there’s rarely any need to delve into the screen menus. I have read
criticisms that the top two dials can’t be identified by touch but I haven’t
found this a problem as I can tell which is which from their position in
relation to the shutter button. The EVF itself is excellent in bright light
though a little grainy and dark with details hard to see in low light. I still
use the tilting screen a great deal, especially when taking low or overhead
shots when it’s much easier to use than the viewfinder, but for many shots I
have returned to the viewfinder. I wouldn’t want a camera without both now.
The NEX 7 has a good handgrip and feels secure held in one
hand. I can switch it on, alter settings and take pictures one-handed too,
though I rarely need to do this.
The Sensor and Image
Quality
 |
| 18-55 @ 21mm, 800 ISO, f5.6 @ 1/20 |
The NEX 7 has a 24 megapixel APS-C sized sensor, which is
twice as many megapixels as the Canon 450D and four times as many as my first
DSLR, the Canon 300D, both of which have sensors the same size. I was concerned
initially about all these pixels as the standard wisdom was that cramming more
onto a sensor made images noisier, especially at high ISOs. Perhaps, I thought,
the 16mp NEX 5N would be a better choice. Once reviews of the camera appeared I
was reassured though, as they all said that high ISO results were okay -
slightly noisier than the 5N but not significantly so. I also realised that as
I rarely shoot at anything more than 400 ISO, and mostly stick to 100, this
shouldn’t be a major concern for me anyway. I didn’t think I needed 24mp but I
didn’t think it would be a disadvantage.
Once I started using the camera I quickly realised that 24mp
actually had one big advantage and that was that I could crop pictures and
still have high quality images. And for backpacking and hiking being able to
crop pictures is a great boon as it means telephoto shots can be taken without
a heavy telephoto lens. I now often take pictures with the intention of
cropping, knowing that the results should be fine.

Just how good the sensor is compared with other cameras I
can’t say from my own experience, other than that it’s far superior to the 12mp
Canon 450D one, which isn’t surprising as that’s now an old camera.
DxOMark
however measures sensor qualities and publishes comparative lists. Their
findings place the NEX 7 as equal 10
th of all the cameras they’ve
tested, with the same score as the much heavier and more expensive Canon EOS 5D
Mk III DSLR and better than most other DSLRs. The NEX 7 also gets a higher
score for dynamic range than the EOS 5D, which is important for landscapes.
Where the big DSLR wins out is in high ISO low light performance, which is less
important for me. Now I would never have a considered a camera as heavy, bulky
or expensive as the Canon 5D anyway but it’s good to know that the NEX 7 can
produce images of the same quality.

The NEX 7s ISO settings run from 100 to a ludicrously high
16,000. My unscientific findings are that up to 400 images are virtually
noiseless and that 800 and 1600 are still very good. At 3200 noise is visible,
though not that intrusive. At 12,800 noise is very visible but images are still
okay if not cropped or blown up much and if the subject matter lends itself to
a grainy look.

A big complaint about the NEX cameras has been the lack of
choice in lenses and the mediocre quality of those available. My preferences
have always been for three zoom lenses - wide angle, mid-range and telephoto.
This is what I used with my film and digital SLRs. When I bought the NEX 5N
only a mid-range zoom was available and for a year I used this. When I wanted
wider angle or telephoto shots I used the Canon 450D, which effectively became
a back-up to the NEX, an unsatisfactory situation due to its weight and bulk. I
did try a converter that allowed me to use the Canon lenses with the NEX but I
lost any control over the aperture and there was no autofocus so I decided that
for outdoor use it was unsuitable.
Initially I just used the 220 gram 18-55 f3.5-5.6 mid-range
zoom with the NEX 7. I wanted more lenses though so I could carry the NEX 5 as
back-up and not bother with the 450D. I ordered a Sony 55-210 zoom, but had to
wait several months for it to become available. In the meantime I purchased a
second-hand Sony 16mm f2.8 lens from eBay, second-hand because reviews
suggested it was a poor lens so I didn’t want to splash out the full amount and
find this was correct. In fact for my usage it’s fine. However 16mm is only
slightly wider than the 18mm of my standard zoom so I soon added Sony’s Ultra
Wide Converter, which turns it into a really wide 12mm lens. Because the converter
can be quickly twisted on and off this gives a two-focal length unit, though in
practice I nearly always use it at 12mm. The 16mm weighs a mere 66 grams; the converter
129 grams.

Another complaint about the NEX 7 has been that there’s a
magenta cast with wide angle lenses. I haven’t found this to be so. I’ve found
there’s a purple cast. I first noticed this with some grey clouds, though,
oddly, only on one side of the image. As I always shoot raw it’s no problem
removing this when processing the images in Lightroom. At first I did adjust
the magenta, assuming this was the problem due to the reviews I’d read, but it
did nothing. Adjusting the purple then quickly removed the cast.
Eventually the 55-210 lens did arrive. It’s much bigger and
heavier than the other lenses (379 grams) and not one I’d carry on a long
distance or multi-day walk unless I felt I really needed it. However for day
hikes and shorter backpacking trips it’s useful and the results are good.
Of these lenses only the 16mm lens is really small. With it attached
the NEX 7 can be slipped into a large pocket. With the Ultra Wide Adapter or
the zoom lenses this isn’t possible. 16mm is too wide for general use for me
though so I was on the lookout for a more standard length lens when the 145
gram Sigma 30mm f2.8 lens appeared. This is a delightful little lens; small,
light and capable of excellent results. I’ve found myself using it surprisingly
often and if I only carry one lens to keep the weight down this is it even
though it isn’t a zoom and doesn’t have image stabilisation, unlike the other
lenses (I think this more important with focal lengths over around 40mm
anyway).
This collection of lenses covers most of what I need though
I would like an equivalent to the 24-70mm zoom that was my most used lens with
film cameras. In fact I’ve wanted such a lens since I changed to digital DSLRs
so I’m pleased that Sony are said to be bringing out one in the next few
months, a 16-50 (equivalent to 24-75mm in 35mm) pancake lens that will
hopefully be lighter as well as smaller than the 18-55. It could be the lens
for trips where I only carry one.

Carrying
At present I’m carrying the NEX 7 in a LowePro Apex 100 W
padded case (232 grams). This has room for the camera plus any lens but the
55-210 and will also hold a spare battery and memory cards. It has an effective
rain cover and is quite compact. However I’d rather have a click buckle fastened
lid than the zip round one as the latter is a little awkward to use. The lenses
are carried in Zing neoprene pouches in the pack.
Conclusion
Is the Sony NEX 7 the best camera for backpacking and
hiking? I don’t know. It must be one of the best though, given the low weight
and bulk and high image quality. It’s definitely a camera for photographers who
want the best results and who are likely to make large prints or have images
published. To get the best from it you need to shoot raw, watch the histogram
and take care with the processing. If you don’t want to be bothered with any of
that then a simpler, lighter, less expensive compact or even one of the better
camera phones should be fine. But for committed photographers who venture into
the wilds the NEX 7 is excellent.
Addendum: Criticisms
I've been asked if there are any flaws with this camera at all. For me there are two minor ones, both complained about, sometimes loudly, by other reviewers as well. The first is the video button which is positioned so it is easily pressed accidentally. I've shot a few short boring videos by doing so. It can't be locked, something Sony should address. The second annoyance concerns the EVF. This comes on when you put it to your eye, which is excellent. However if you carry the camera slung on your chest it also comes on, and eats up battery life. Until I realised this was happening I was puzzled at to why the battery was losing power quickly even when the screen was off. Now I switch the camera off when there's going to be more than a few minutes between taking pictures.
