(I tried to post this review before, but it disapeared; no doubt it willappear twice now!)
The Minolta A2 is arguably the most comprehensively specified of thecurrent crop of prosumer 8 megapixel cameras. It is also competitivelypriced relative to the rest of the pack. If nothing else, this makes itworth looking at.
I have been in possession of my A2 for two weeks now and have put itthrough its paces in a number of different lighting conditions. So far theresults that I have had with it have varied from extremely competent tobreathtaking.
Having read a number of reviews I was concerned about image noisiness.Let's make no bones about this. Viewed at 100% pixel resolution there is asmall amount of noticeable noise on images even at ISO-64. Initially thismay seem disappointing, however, in practical tests I have found it to belargely irrelevant. Taking an unprocessed, ostensibly noisy image, andprinting it out to A3 gives a completely acceptable image quality.Interestingly, when I took such an image and an identical, noise reducedimage (using Noise Ninja) over half the people I asked for a preferencesaid that they thought the unprocessed image looked better.
Doing the math reveals that from a 3264x2248 image, you can print at A3(11.75x16.5 inches) at 203 X 191 pixels per inch (PPI). This is just belowbottom end of what is conventionally thought to be photo quality.Nevertheless, a well saturated, properly exposed picture printed at thissize can be nothing short of stunning. Expanding beyond that will start toreveal flaws in the image - but this is offset by the fact that postersize images tend to be viewed from larger distances. For me the ability totake a crop out of the centre of an image and still print it at photoquality on A4 is an absolute joy.
So how easy is it to get that well saturated, properly exposed original?So far I have found it to be pretty painless. The camera's automaticsetting does a pretty good job in most lighting conditions. If it gets itwrong, tweaking the exposure setting a stop or so in either direction iseasy enough. The real time histogram can be a real help in deciding if theimage is going to be over or underexposed. In places where more control isneeded, the manual settings are easily adjusted and cover a goodrange.
As the ISO number increases, so does the noise level. I took some indoorshots at ISO-400 with no flash and they are noticeably noisy. Running themthrough Noise Ninja makes a dramatic improvement; but they are still notbrilliant. For this kind of work the only options seem to be to use aflash, a lower ISO value and a tripod or a different camera. Long exposureshots work nicely enough with a tripod.
Functionally the camera is well laid out. I have found it very easy tofind my way around. The learning process is help along by the manual(sadly only provided in PDF) which is comprehensive and clearly laidout.
In operation, the manual zoom is a joy to use and the auto-focus isgenerally quick and accurate. The anti-shake also seems to do the trickquite nicely. I have taken crisp, shake free images at shutter speeds Icould only dream of with other cameras. Sadly the manual focus is harderto set correctly - the Electronic View Finder (EVF), whilst better thanthe competition, is still not really up to the task. The EVF switches toblack and white in dim lighting and remains usable, however, under brightlighting the lack of contrast makes it very difficult to see.
I can't answer the question for anyone else of "should they buy thiscamera?". From some reviews I have read it may be that there are other 8Megapixel cameras which have a slightly better image quality. So much ofthe choice depends upon your criteria. However, for my part all I can sayis that the image quality that I get making prints is everything that itshould be, and for my requirements the feature set places this camera wellahead of the competition. As such I would have no qualms aboutrecommending it.
Pros:
Excellent lens, with a good range.
Fast, accurate auto focus
Easy to use
Short "switch on to shoot" time
Can keep shooting whilst images save
Cons:
Noisy at higher ISO
Lack of optical viewfinder
Poor manual focus
