Olympus PEN
E-P1 Review - March 2010 |
The missing link from the modern line up of digital cameras is
the rangefinder type camera. A camera that offers high degree of flexibility
like a DSLR but in a more compact body. Not everyone wants to carry
around a DSLR and digital compacts are limited by their very small image
sensors. The Olympus E-P1 steps in to fill this gap. Being
spiritually based on the old PEN Olympus rangefinder cameras but
built employing modern digital technology.
The E-P1 is based on the 4/3 sensor standard but has done away
with the mirror in order to have a more compact body. The lens mount
has been reduced in size to facilitate smaller lens but maintains
compatibility with the standard 4/3 lenses through the use of an
adapter.
The E-P1 is feature packed to make it usable
for the novice but also comprehensive enough for the serious
photographer. It's solidly built and looks designed to last.
The Olympus E-P1 feature packed
with enough built in tools to tackle a wide range of
situations. The key features are as follows:
- 12.3mp Live MOS image sensor
- TruePic V image processor

- Built-in I.S. with max. 4 EV steps efficiency
- New developed GUI for easiest operation via Live Control
- Twin dials for easier handling
- HD movie with stereo sound
- Art Filters
- Art filters can be applied to previously
taken RAW images.
- Level gauge
The E-30 has a very comprehensive custom menu
so the camera can be specifically tailored to user requirements.
The E-P1 provides image stabilisation built
into the body of the camera rather than having it in each lens. This
has the benefit that any lens that is attached to the body can be
image stabilised.
There are three operating modes provided for
the image stabiliser:
- IS 1 - Image stabiliser on
- IS 2 - Only vertical axis stabilised for
panning horizontally
- IS 3 - Only horizontal axis stabilised
for panning vertically
For non-4/3 lenses, the focal length can be
manually entered.
The E-P1 has 11 defined AF points that covers the
central area of the screen. These are all contrast based focusing
points (like used in digital compact cameras) and they operate in
one of two modes:
-
Wide area AF mode - The
camera will automatically determine which of the 11 AF points to
use based on the subject position distance and position within
the screen.
-
Single point AF mode -
The camera focuses using the pre-selected AF point.
There are three main focus
modes provided:
-
S-AF (Single AF)
-
C-AF (Continuous AF)
-
Manual
Additionally the S-AF and
Manual focus can be used together to manually fine adjust the focus
after autofocus has taken place.
When manual focusing the
focusing area can be magnified up to x10. The arrow pad is used to
select the area of the LCD screen to magnify.
Pressing the power button
powers up the camera promptly and levels the power button
illuminated green as a reminder. The Super Sonic Wave Filter (SSWF)
is activated every time the E-P1 is powered on to ensure the image
sensor is kept clean. There does not appear to be a way to
deactivate the feature but the feature works quickly. The much
larger shutter release button neighbours it. Usually, the exposure
mode dial on the left hand side of the camera top plate has been
recessed which gives the E-P1 a sleek appearance. The Exposure mode
dial presents: PASM as well as iAuto, Art Filters, SCN and Movie.
Customisation
Every photographer whether a relative novice
or very experienced have their own preferred way of using a camera.
The E-P1 just like Olympus's DSLRs has a very comprehensive set of
customisation options. In fact for the casual shooter they might be
seen as overkill as Olympus seems to of packed in ever possible
option a photographer may require with the result that initially it
feels easy to get lost in the options without prior knowledge of the
Olympus menu system. Unusual options like the ability to set the
rotational direction of focus can come in handy depending on which
camera system previously used. The dual dials can be customised for
example to set one as a exposure compensation dial. Going through
the collection of customisation options shows the potential of the
E-P1.
LCD Screen
The E-P1 does not have a
built in viewfinder and like a digital compact camera it uses it's
3" LCD screen as the main way to view what the camera will capture.
The LCD pixel resolution is just 230,000 which is decent enough for
most purposes but well below the 900,000 pixels that the leading LCD
displays use.
The shooting information
displayed is comprehensive and very much follows that presented on
the E-series DSLRs in their liveview modes.
Image Aspect Ratio
The standard aspect ratio is of course 4:3 but
the E-P1 also has provision for the following aspect ratios:
Although it is
straightforward to produce similar aspect ratios during post
processing through cropping shooting with a different aspect tends
to case the user to reconsider how they should compose their photo.
Full Auto Modes
The Program mode will determine the aperture
and shutter speed combination for the required exposure. The program
line is not only determined by the brightness faced by the camera
but by the type of lens attached. In practise it was found necessary
to make use of the program shift in order to get the required
aperture/shutter speed combination. However, there are times when
there is no time to think about exposure controls and the program
mode serves its purpose here. There are a number of
program modes design to make life easier or to inject a bit of art
to the results. They are: iAuto, Art Filters and Scene modes.
iAuto
For pure simplicity in shooting the iAuto has
been designed to analyse the scene the E-P1 is pointed at and set
the appropriate shooting mode. The camera will try to determine
whether the scene is one of the following:
- Portrait
- Landscape
- Sports
- Macro
- Night Scene
Generally, this mode worked well and is the
mode of choice for those who just want to point and shoot.
Scene mode
The scene modes permit the user to
specifically select the option that matches the scene that is to be
captured. The range of options is extensive and covers just about
most type of scenes users will encounter:
Art Filters
The E-P1 features Art Filters to give photos
an added dimension. There are six filters provided: Pop Art, Light
Tone, Soft Focus, Grainy Film, Pale and Light Colour, and Pin Hole.
These make an interesting variation to the scene modes that are also
provided.


The above images
originally taken with the Olympus E-30. The results from the E-P1
Art Filters are the same
The Art Filters are saved in JPEG (sRGB)
format. If shooting in the RAW format the Art Filters can be applied
during post processing using Olympus Studio 2 software.
Advanced Shooting Modes
The usual PASM shooting modes are provided on
the E-P1 for the user who wants to take control and determine the
exposure.
In the Manual mode Bulb can be set for shutter
speeds beyond 60 seconds. Rather than relying on a cable release the
E-P1 has a bulb timer which provides speeds of 1, 2, 4, 8, 15, 20,
25, and 30 minutes. In the Bulb mode the image stabiliser is forced
off. This is a good inclusion as in bulb mode the camera will be set
on a tripod or steady surface and an active image stabiliser may
introduce some image blur.
Exposure Metering
There are a number of metering options
provided:
- Digital ESP - Evaluative metering using
on 324 zones to analyse a scene. This is the standard metering
mode of the E-P1.
- Centre Weighted Average
- Spot
- HI Spot - highlight control
- SH Spot - shadow control
Under most circumstances the ESP performed
well not requiring over use of exposure compensation. The E-P1 can
happily be used in this mode with the other metering options
employed for either specific lighting conditions or artist
endeavours.
Exposure compensation adjustment was easily
achieved by pressing the exposure compensation button on the top of
the camera or, as was preferred, defining one of the dials (in this
case the sub dial) in the costume functions for exposure
compensation adjustment.
White
Balance
The E-P1 was all the expected white balance
presets of:
- Auto
- Daylight
- Shadow
- Tungsten
- Flourescent
- Flash
- Custom
Each white balance setting can be fine tuned
according to requirements with adjustments made between Amber and
Blue and between Green and Magenta. Provision has also been made for
WB bracketing using the same parameters.
Auto ISO
The ISO can be determined automatically by the
camera based on lighting conditions but the E-P1 has provision to
specify the range over which the ISO can be selected. The minimum
ISO can be set as ISO 200 and the maximum up to ISO 6400. In
practice it was found the range ISO 200 to 800 keeps results optimal
although results up to ISO 1600 can be acceptable depending on the
subject matter. Image quality beyond ISO 1600 looks obviously
degraded and may be considered for artistic or emergency purposes
only. The E-P1's image stabiliser helps to reduce the need for very
high ISO settings as long as subject movement does not have to be
frozen.
When setting the ISO manually, the ISO can be
set either at 1-stop intervals or by finer 1/3-stop intervals.
Gradation
High contrast scenes are
always very challenging for a camera to capture well. Either the
highlights burn out or the shadow areas become blocked up. The
Gradation feature of the E-P1 has been designed to analyse such
scenes and make adjustments to produce a more controlled scene.
There are four options available:
- Normal - the standard
setting for normal use
- Auto - the gradation
is adjusted according to the scene presented
- High Key - emphasis is
placed on reproducing bright subjects
- Low Key - emphasis is
placed on reproducing dark subjects
Auto Gradation produced
very pleasing results in a range of shooting conditions but it has
to be used with care. As found with the Olympus E-30 (and with other
camera brands) gradation makes most of its adjustment to the mid to
shadow areas of an image. This has the unfortunate side effect of
boosting any noise deficiencies in the image. The lower the set ISO
used the better the results so auto graduation is best avoided when
high ISOs are set.
It is worth noting that
Gradation adjustments can be applied after the fact during post
processing using Olympus Studio 2 software. This software can also
be used to under auto gradation. Both these cases are possible as
long as the shots where taken in the RAW format.
Level Gauge
Keeping horizontals horizontal can be a
challenge at times. It is all too easy to end up with a sloping
horizon. Through the custom functions it can be activated and if
necessary it can also be re-calibrated (should the need arise). Both
horizontal and vertical information is presented.
The LCD screen shows two scales with one
indicating the horizontal alignment and the other the vertical
alignment. The implementation works well but with the alignment
information on the screen exposure information as well as the
histogram display are not available.
External Flash Unit
The E-P1 does not have it's
own internal flash and so is dependant on external flash units. It
can shoot with the FL-20, FL-36R and FL-50R flash units but they can
unbalance the camera. The FL-14 is more suited the camera with its
more compact and low profile design. Unfortunately the E-P1 does not
have any wireless flash capabilities.
The Optics
The Olympus E-P1 was reviewed with the
following lenses:
- M.Zuiko Digital 17mm f/2.8 Pancake lens
- M.Zuiko Digital ED 14-42mm f/3.5 - 5.6
lens
More information on these lenses
will be provided in separate reviews. The lenses equate to 34mm lens
and 28-84mm lens in 35mm format respectively.
Image Noise Analysis
Image noise is always a concern for the modern
photographer especially those who intend to make significantly big
enlargements. The E-P1 generally copes well in bright daylight
conditions (although image noise can be introduced can raised if Auto Gradations is enabled) but when light levels drop
things get more interesting. The noise filter can be set to one of
the following conditions: off, low, standard and high. All the
photos illustrated here were shot with the noise filter set to
standard.

 
ISO 200 - f/4 at 1/4 sec. (100% crop)
 
ISO 400 - f/4 at 1/8 sec. (100% crop)
 
ISO 800 - f/4 at 1/15 sec. (100% crop)
 
ISO 1600 - f/4 at 1/30 sec. (100% crop)
All the above photos were shot
handheld relying on the built-in image stabiliser to maintain sharp
results. The ISO 200 shot at 1/4 second with the 17mm (34mm
equivalent in 35mm format) pancake lens attached seems to of reached
the limited of the images stabilisers abilities. Keep in mind the
longer the lens focal becomes the more challenging it will be for
the image stabiliser to produce sharp results.

ISO 6400 - f/3.5 at 1/125 sec.

ISO 6400 - (100% crop)

ISO 6400 - (100% crop)
ISO 6400 is probably best left
for emergency or artistic use. Detail and definition at this setting
is severely reduced resulting in photos best printed at a smaller
size than expected from a 12mp sensor.
Long Exposure Photography
Long exposures are another situation where
image noise can be an issue. The E-P1 provides noise reduction to
deal with this situation. The following sequence of photos the
typical noise levels at various ISO settings.


ISO 100 -
f/20 at 60 sec. (100% crop)

ISO 200 - f/22 at 30 sec. (100% crop)

ISO 400 - f/22 at 15 sec. (100% crop)

ISO 800 - f/22 at 8 sec. (100% crop)

ISO 1600 - f/22 at 4 sec. (100% crop)

ISO 3200 - f/22 at 2 sec. (100% crop)

ISO 6400 - f/22 at 1 sec. (100% crop)
It is worth keeping in mind that for any given
exposure the E-P1 can only be used after double the exposure time.
For example a 30 second exposure results in another 30 seconds where
the shutter is closed and a blank image is take to subtract noise
from the main exposure. With this in mind a 30 minute exposure will
therefore mean the camera will be ready to shoot again after an
hour. This noise reduction feature can be deactivated if required.
Shooting with the E-P1
The E-P1 was used for this review with the
camera saving RAW + JPEG together. Images were saved on a SanDisk
Extreme III SDHC Card 4GB.
The following shooting data was noted:
- In continuous drive
mode: RAW+JPEG (SF) - 19.5 sec for 9 frames.
- Continuous drive mode:
RAW only - 7.2 sec for 13 frames.
- Continuous AF with
continuous drive dropped frame rate from 3fps to 0.5fps.
All photos reproduced here originally shot in
RAW and processed to JPEG using Olympus Studio 2 software.
The Plus Points
- Build quality
- Image quality
- In body image stabilisation
- Dual control dials
- Level gauge
- Movie quality
- HDMI output
- Customisation
The Negative Points
- AF performance could be better (but still
acceptable)
- Could do with AF aid light for low light
conditions
- No built-in flash
- No wireless flash control
- AF motor noise can spoil otherwise great
movie recording
- Single AF point too large for some
purposes
- Battery and memory card cannot be
accessed whilst on a tripod
Summing up
It is good to see Olympus breathing life back
into the missing segment
of cameras, the range finder types. The E-P1 is the modern
equivalent of the rangefinder. It sits nicely between the digital
compacts.
The E-P1 turned out to be a very capable and
fun camera to use. Just
about all the options a photographer could wish for have been
provide.
It's image processing seems to be an improvement on that in the
E-30.
The lack of built in flash maybe welcomed or
seen as a serious
omission depending on the users requirements. Those who mainly like to shoot by
available light will hardly miss the flash and praise the fact that
the E-P1 has an image stabiliser built into it's body. It is
possible
to shoot down to 1/6 second hand help without recourse to a tripod.
However, there are times when a bit of fill flash can help matters
and that is where the FL-14 flashgun would come in handy.
The autofocus performance can be seen as one
of the weaker aspects of
the camera if the intention is to capture action. It is adequate for
most purposes. Added flexibility would of been appreciated in terms
of
being able to adjust the size of the spot focus area because at
times
it felt too large when wanting to focus on small detail (such as the
stamen of a flower). Another useful addition would be to have a
focus
assist light for dealing with low light or low contrast situations.
All in all the Olympus E-P1
was an enjoyable camera to use under a range of lighting conditions.
Although not a true compact with the 17mm pancake lens attached it
will be able to slip into any camera bag or jacket/coat pocket. The
14-42mm lens provides the versatility that the modern photographer
demands whilst remaining relatively compact when the lens is not in
use.
The E-P1 should appeal more
to those that enjoy photography especially the serious amateurs and
pro photographers who want a compact light weight camera with DSLR
image quality. The camera is more geared towards people, landscape,
and still life photography. It is a camera that screams to be
taken everywhere and therefore makes a great camera to travel with.
When inspiration strikes the E-P1 has the necessary features to help
'pen' that photographic classic.
