Minolta DiMAGE F100 Review
Timings & File Sizes
The F100's performance was good in one respect and annoying in others. Startup time was a longer than average, this appears to be down to the very slowly extending lens. The other frustration is zoom speed which can seem snail like, especially if you really need to zoom in to catch the moment. Otherwise performance was on par with other compact four megapixel digital cameras, Auto Focus seemed to be within acceptable bounds and shot to shot times were also fairly good. Good in some respects, slow in others, a mixed bag.
Timing Notes: All times calculated as an average of three operations. A Viking 128 MB Secure Digital card was used for timings. Unless otherwise stated all timings were made on a 2272 x 1704 FINE JPEG image (approx. 1.3 MB per image).

Auto Focus LAG is (roughly) the amount of time it takes the camera to autofocus (a half-press and hold of the shutter release button), this timing is normally the most variable as its affected by the subject matter, current focus position, still or moving subject etc. This timing is an average.
Shutter Release LAG is the amount of time it takes to take the shot from the moment you fully depress the shutter release button, measured both as a time including auto focus and a time assuming you have already pre-focused by holding a half-press of the shutter release.
Continuous drive mode
The table below shows the results of our continuous shooting test, indicating the actual frame rate along with maximum number of frames at a selection of image resolution / quality settings and how long you would have to wait after taking the maximum number of frames before you could take the next shot. A Viking 128 MB Secure Digital card was used for this test.
|Image Type||Frames per sec
||Max no. of frames||
|2272 x 1704 FINE||1.6 fps||5||7.2 sec|
|2272 x 1704 STANDARD||1.6 fps||8||3.4 sec|
|1600 x 1200 STANDARD||1.6 fps||11||3.8 sec|
|1280 x 960 STANDARD||1.6 fps||24||2.5 sec|
|640 x 480 STANDARD||1.6 fps||102||2.0 sec|
|*1||You can take a frame (holding your finger on the shutter release) as soon as there is space in the cameras internal buffer, writing continues "in the background".|
Again another good implementation of a writing buffer on a Minolta digital camera. The F100 operates seemlessly with data in its write buffer, at no time does the camera feel 'bogged down' with images being written out to the storage card. A good performance for such a compact camera, a respectable frame rate (albiet not blistering) and a fairly good buffer size.
File Flush / Display Timing
Timings shown below are the time taken for the camera to process and "flush" the image out to the Compact Flash card, the timer was started as soon as the shutter release was pressed (shutter click was heard) and stopped when activity indicator LED beside the storage compartment went out. This means the timings also include the cameras processing time and as such are more representative of the actual time to "complete the task". A Viking 128 MB Secure Digital card was used for this test.

|*1||Instant playback disabled. Even with instant playback enabled writing starts immediately.|
|*2||The first 9.2 seconds of this are taken up by camera processing, so the file write itself takes just 8.3 seconds, thus 1.3 MB/sec write speed - impressive. Playback load speed is less impressive.|
|*3||The F100 doesn't buffer or pre-load images, the camera loads the image from the SD/MMC card every time you press the left or right arrows to browse.|
|*4||With JPEG it's difficult to predict the exact size of an image file because it will vary a fair amount depending on the content of the image (especially the amount of detail captured). For example, take a photograph of a fairly empty wall and you'll get a small JPEG, take a photograph of a bush with a lot of detail and you'll get a larger image. File sizes here are closer to the later, the larger size of file you should expect.|
We found the overall processing & write performance of the F100 to be very good, around three seconds for a high quality four megapixel image is very good. We did notice a difference between brands of SD card, the Viking 128 MB SD card used for the tests above proved to be approximately 30% faster than the same capacity SanDisk SD card.
We ran the camera through our new battery life test. This test is designed to be fair and comparative to each camera and battery type:
- Take 4 shots without flash
- Wait 2 minutes (50% of the time powering the camera off)
- Take 1 shot with flash
- Wait 1 minute
All batteries had been fully discharged and recharged before the test and all cameras were reset to their factory default settings. Here are the results:

|Other test notes:|
| LCD monitor is left on during
the battery test
The camera is powered off half of the time and left on half of the time (switch every 10 iterations)
There are now higher capacity AA NiMH batteries available, however in the interests of fair
comparison we will continue to use our 1600 mAh test set
The DiMAGE F100 lasted relatively well, certainly in line with other double AA powered digital cameras. That said you may wish to carry a spare pair of batteries with you on longer shooting trip.
