i forward the article below from other site, it make me worry about that! does anyone has this problem?

Hi everyone.


I am just writing to let you know that the new D70 users in Spain, Hong Kong, China, South Korea and Japan have found a problem with the colour reproduction of the D70, especially evident when taken at shutter speeds of 1/2000 or more (D70 supports up to 1/8000).

The problem is that the pictures display a very clearly uneven distribution of colours - the left of the picture is greenish, and the right of the picture is reddish.

It has been reported that an official enquiry has been directed to Nikon's Japan HQ by the HK-Nikon, and sales of D70 in Seville, Spain has been halted temporarily as a safety measure.

The largest digital SLR internet community in South Korea, http://www.slrclub.com, has had in excess of 300 postings just today only (20-Mar-04) of users confirming that their newly purchased D70 indeed does have this problem that many users described as outrageous and appalling. The users have already given this strange phenomenon a name within 24 hours of the problem being identified: namely, 'the traffic lights effect'.

A large number of users reportedly have contacted their vendors demanding refunds, and equally large number are hoping that firmware upgrades will fix the problem, with still a large number expressing their disappointment at Nikon in which they gave their 100% trust and bought the camera even before it was officially released.

Below is the link to the picture that apparently started it all, by a user in China who took a picture of flowers on a tree with the sky as the backdrop, and found that the sky was greenish on one side and reddish on the other.

Now the issue is this: so many users bought the D70 because of its specs which includes shutter speeds of up to 1/8000, and many improvements over its higher-priced brother, D100. But since it has been reported that close to 100% of users who tested their 1/4000 and 1/8000 shutter speeds on the sky have reproduced the problem of uneven colour reproduction, the users feel betrayed and lost.

If you also have a D70, then HERE ARE THE INSTRUCTIONS FOR TESTING THIS PROBLEM.

1. Manually set your shutter speed to 1/4000 or 1/8000.

2. Point toward a white wall in your living room, or preferably the sky (so that any problems can be identified).

3. Review your photo on your computer. According to reports there has not been any D70 that did not reproduce this problem.

Here are more photos displaying this problem. Download them and change the extension from .jpe to .jpg, which will allow you to see the photographic details like shutter speed, camera model, time of photo taken etc etc. (These are all posted by korean users who heard of this problem, tested their D70 and found the exact problem that was being discussed)

Hope Nikon will be able to sort out this serious issue, which at the moment is causing uproar in internet communities that are built for Nikon lovers.

呢個題目真係攪到滿城風雨, 但我部D70唔多覺, 就算真係有又點, 我廿年影相生涯用1/1000"影相次數可以用十隻手指數得晒, 1/2000"都未用過, F4/F90/F100的1/4000"和1/8000"都係試閃燈頻閃時玩過, 冇實際用途。唔係話我買左D70就同佢講好說話, 相反佢回收我仲高興添, 等佢趺價三成時買部新囉! XDDDD

I agreed with what Oldpear said. I haven't used 1/2000 or even faster before in taking photograph.

But, to be fair to customer, Nikon should do something to solve the problem if it is true.

Oldpear said his camera had no problem, why ??, QC problem or ????

師兄們夠境以1/1000sec.以上測試Shutter有什麽問題呀?
我都唔太明白mikehunghk師兄的意思 ?

As i know in the past, with 135mm film camera, there may be some lenses will have uneven exposure on the photo while it took with fast shutter speed, i.e. 1/1000 or above. For ppl rare use over 1/1000 shutter speed then this wouldn't introduce any big trouble.

I don't know this will be the reason of this problem or not. But i guess this may be a possible reason. And i also think this is a very minor problem... Or other digi cams may also have similar effect but ppl don't discover or care that.

Above is only my personal opinion, pls point out any mistake.

放心啦！D人開始試其他機，原來都有呢個問題。
用試火箭既標準去試車，乜車都死啦！

雖然高速快門左右偏色, 不是對實拍有多大影響, 但足見新機仍有很多地方要改善, 未買既朋友還是等多一陣為妙
