(Well, no, of course not, > history is no predictor of the future, eh?) Hmm. There is some truth there, but certainly not the whole truth. I would never use my zooms for portraits, macro, most sport and landscape work. I use primes (or: fixed focal length lenses if you prefer). I do use my two high quality, non-variable-aperture zooms for some sports, for hiking, fairs, parties and other less structured work. There's no hard line here, but usually the right lenses for the job. Having said that, when Minolta come out with their D7D, I will consider ordering it with the 28-105 (var aperture) lens as it is very good as zooms go, and very appropriate to the camera. However, there are another lenses with higher priorities on my list, inlcuding at least 2 primes and one (non-var aperture) zoom. There remain in the SLR world people who swear by fixed-focal and those who accept the quality limitations of zooms. One point is that as the optics have improved for the zooms, they have likewise improved for the better primes as well... so the primes always come out ahead if that is important to the photog. The "high quality" zooms rarely have a zoom ratio of more than about 2.8:1 at that, most exhibit some quality limitations at wide angle, fully open. 17-35 f/2.8, 28-80 f/2.8 and 70-200 f/2.8 are the three "professional" zooms you are likely to see carted around by pj's and other folks with narrow time constraints on their work. There is no "super zoom" that is regarded as having sufficient optical quality for most professional work. Could a pj use a super zoom? Probably, except for the limitation in aperture (although the realtively noiseless high ISO help), the mtf quality he's expected to deliver for a newspaper is not exceedingly high... but I've seen no pj's to date with less than the top end glass ... as recently as a few weeks ago at a sports event. Will there one day be a 28-300 f/2.8? Or better? I don't know. One way is to make the sensor even smaller than on cameras like the G3, but with higher res ---and--- lower noise. Quite an objective |
