Zoom lens quality paradigm still holding?
The quality zoom lens paradigm used to be that a zoom ratio of 2.5:1 was a limit to high quality zoom lenses (3:1 in some cases). In part this defined (or was defined by) the press holy trinity of: 17-35 f/2.8 28-70 f/2.8 -- 28-80 f/2.8 80-200 f/2.8 -- 70-200 f/2.8 With todays lens formulations, is the ratio higher? Or is a higher ratio reasonable, but only with cropped sensors behind full frame glass? -- -- r.p.e.35mm user resource: http://www.aliasimages.com/rpe35mmur.htm -- r.p.d.slr-systems: http://www.aliasimages.com/rpdslrsysur.htm -- [SI] gallery & rulz: http://www.pbase.com/shootin -- e-meil: Remove FreeLunch. -- usenet posts from gmail.com and googlemail.com are filtered out. |

There's only one Nikkor I can think of and it's not that extreme or highly prized though I've not heard complaints: 17-55 DX (25-82 eq) at 3.2x Canon has the same, plus: EF 24-105mm f/4L IS USM at 4.3x -- Paul Furman www.edgehill.net www.baynatives.com all google groups messages filtered due to spam |

There's only one Nikkor I can think of and it's not that extreme or highly prized though I've not heard complaints: 17-55 DX (25-82 eq) at 3.2x The new 24-70mm f/2.8 Nikkor is a better lens than the 28-70mm version and its 2.92 zoom ratio exceeds any in Alan's holy trinity. I recently compared my 70-300mm VR with a 70-200mm VR + 2x TC. At 300mm (supposedly where the 70-300mm isn't at its best), it matched the 70-200 + 2x TC's clarity and resolution. When both of these were compared with a 105mm Micro Nikkor + 2x TC (at 210mm), the first two were evenly matched and both seriously outperformed the Micro Nikkor. Because of it's poorer AF performance and smaller aperture, the 70-300mm VR may not be considered to be a top notch pro lens, but its image quality (at least my copy, anyway) is up there with the pro zooms, and it has a 4.29 zoom ratio. I haven't tested the 80-400mm VR Nikkor (5x zoom ratio), but I wouldn't be surprised if it was at least the equal of the 70-200mm VR + 2xTC at 400mm. This isn't to say that the 70-300mm and 80-400mm lenses are pro quality, but they're close, and that at least some pro zoom lenses fall back into the pack when they're saddled with a 2x TC. BTW, the price of the 70-200mm VR just increased by $20 at B&H, and many think that it'll go up more than another $200 on Feb. 1st. Get 'em while they're hot and cheap. I'll pass. |

There's no doubt it's a high-end lens if used with a camera of the correct format. Next you'll be telling us that none of the new Olympus 4/3 glass is in the high-end basket. |

There's no doubt it's a high-end lens if used with a camera of the correct format. Pros tend to want the highest performance and that leans to FF. No - it leans to medium format. "FF" is legacy from 35mm film which was based on compromise. Yeah - I know that a D3x wipes the floor over an H3d at high ISO, or for action, but you're showing bias based on your preference of format, and your definition of "pro". Also, unfortunately for D3x, it still looks much like the camera slung around the neck of a tourist who bought it in the duty-free store at the airport - not what ie a top fashion photographer uses in the studio. Next you'll be telling us that none of the new Olympus 4/3 glass is in the high-end basket. Oly took a great gamble with 4/3 and it has not paid off in the pro world. The high end glass is certainly very good (and very expensive) but the format is noise bound (preventing pixel growth) so the performance of the glass is short changed. Despite making some very nice cameras, Olympus never had a serious foothold in the pro world even when they had no "format disadvantage" with 35mm. |

What pros really tend to want are products from Canon and Nikon, not Sony, which tends to target thrifty guys like you. |

I don't think a pro cares what his camera looks like over what the images look like. You surely don't imply that what the camera looks like is an insignificant matter? It's a bit tacky perhaps, but having an image of a hasselblad on a business card seems to work wonders with magazine publishers etc. A Nikon or Canon is what they take to their kid's Saturday soccer games. Many pros used 35mm during the very durable MF days - and not just for location shooting. They were (gasp!) used in the studio as well (shh! It's a secret). The 1966 movie "Blow Up" blew the secret. And today's full frame 35mm sensor outputs quality that rivals drum scanned 6x4.5 or 6x6. There is still room for MF and digital MF but its domain is lesser and lesser. really? Theres more choice in MF digital today than two years ago. For the amount of equipment that needs to be lugged around (35mm size) might as well fill it with the largest sensor rather than a cropped sensor. And that is what so many pros are doing. Of course the Canon pro world has had a lead over Nikon and it's taking a while for the Nikon pro world to catch up. But they will. Canon had a significant lead over Nikon in the last days of 35mm film when digital was very poor quality. Next you'll be telling us that none of the new Olympus 4/3 glass is in the high-end basket.

I don't even expect Sony (nor perhaps Pentax) to survive in the DSLR market with the current crisis. IMO Sony has only succeeded when they innovate (trinitron/walkman etc), but never when they are a "me too". That is regardless of the quality of their camera bodies. Canon and Nikon will squeeze them out in a declining market. Olympus is safe - (particularly micro) 4/3 is an excellent concept. |
