聽講呢部機比以前14n 好好多. 有人試過話重好過 1Ds, 不過佢用開 Nikon ... 不過論 spec 又唔差 ...
14M Pixels, 1:1 focal length 比率, 高iso 都有高質素影像..
不過佢嘅機身就真係唔夠 1Ds 或者1D mark2 好 ...

如果係 nikon SLR 原有用户呢部機係好選擇呢? 起影樓用會唔會最啱呢?

有朋友想買黎影婚紗相. 各位又有咩意見呢?

[vaworld]

我朋友就想佢比 1Ds 平成兩萬, 像素又高ｄ. 如果唔嫌佢機動性低ｄ, 亦係好嘅選擇. 唔知各位用開 dslr 嘅朋友對呢部有咩睇法? 謝謝

I don't know if my information useful, but just tell.

I use DSLR almost every day and I'm using Fuji's S2Pro. Regarding image quality, it is no doubt to be the best. Only 1DS will a little when her FULL CMOS power is used.

All I want to say is the no. of pixel is not everything. Fuji's 6.5M Super CCD producing an image quality of 11M is not a software push. It's a different array using haxegon-shape cell in CCD, producing a more close to film quality then all other square cell CCD.

Fuji S3Pro is comming, better wait and see for yourself.

It is suggested that your friend not to use DSLR for wedding. File size is never big enough. Unless you sure you are not going to print larger than A3 size.

If digital is a must for your friends wedding, you'd better buy a 120 digital back. Though that's another story.

呢部機用全新既CMOS,濾片等改善咗14N既缺點,根據廠方消息,呢部機巳經超過所有中片幅質素!!就係呢個原因,柯記巳經停產所有中片幅數碼機背!!

[vaworld]

真係咁高質素?

我未有試用過呢部機, 有冇人用過, 請比ｄ意見,

謝謝!

事實上一千萬像素以上full frame的CCD/CMOS的解像度(這裡只考慮解像度比較，當然不等同影像質素)，已經等於或優於120菲林，但絕對不能優於所有120的CCD數碼背，因為現在120背已出到22Mpixels。最重要的是：120背的色深和dynamic range遠優於現時所有135DSLR！

[vaworld]

但單係 22M pixels 120機背都遇十萬, 加埋機身差不多可以買三部 SLR/n ... 鏡頭都未計 .... 而且機動性更低. 不過質素就真係一流!

For medium format have superior over 135 for Depth of Field and Lens Performance, the digital back is king in studio and product shot, 135 DSLR is great for outdoor. They can co-exist in difference application.

[vaworld]

Yes, medium format camera has better in image quality but the trend of size of film or image sensor will become smaller just like dc with small ccd size is the main stream in consumer market.

The situation of 135mm vs 1:1.5 or 1:1.6 size image sensor (i.e. 1Ds, SLR/n or 14n vs 300d, 70d, ...) is similar to 6x6 vs 135mm size image sensor. Full 135mm size image sensor cameras will become main stream in high quality demanding commerical applications. 1:1.5 or 1:1.6 size image sensor cameras will become main stream in professional application.

On the other hand, if considering with DOF in 135mm size camera may be better than medium size camera for their lenses are often with larger aperture in similar range. eg. 85/1.4 vs 150/2.8; 135/2 vs 250/4 or else.

[Hercules]

Don't forget medium format have large film/sensor size, can't compare with 135 format directly in focal length and aperture, for the lens F2 in 645, it;s wider open than 1.4 in 135, F4 in 645 > F2,8 in 135. and 80mm in 645 = 50mm in 135 format.

issue about lens quality, if increasing resolution per unit area of sensor, the small defect on the lens will be magified a lot, 135 DSLR will reach the limit of optical resolution with smaller lens sooner than medium and large format.

Multipass Exposure is also not possible on 135 DSLR yet.

[vaworld]

Mr. Hercules, i'm really respect and thanks to ur opinion. Yes, there are many merits of medium format camera over 135 camera.

But in fact the development of medium format camera or even 135 camera is much slower and smaller in digital world than other smaller image size cam. For the quality of smaller image sensor become better and the quality of lenses are also better than the past. We can get similar quality with smaller size medium comparing with larger size medium in the past.

Some features like multi exposure are quite important in film photography but we can obtain similar result with computer applications that's also why this is removed from most 135 dslr.

You are absolutely correct that a lens with same range and same aperture in medium camera will have shallower DOF. But in most of 135 lens in similar range will with a wider opening in aperture than med-size cam, just like a brightest 85/1.4(some 1.2!) having an 60mm diameter of aperture but in medium size, a brightest 150mm lens may only have 2.8 and which is about 54mm diameter of aperture.

In fact, there are some ranges of lenses are missed in med-size cam system just like extreme wide and extreme tele lenses. This is the reason why many new DSLRs are still using old 135 cam.'s mount.

Yes, med-size digital camera backs are really superior in quality but they suffer from cost & less convenience in the competition in digital market. 135 cams also have similar position as them but fortunately, 135 had development a huge range of lenses and accessories.

The digital camera will become smaller and smaller in future and this is the trend.

Above is my opinion only.

[Hercules]

In medium format is not acceptable to have 1.4 aperture as the size of the sensor/film, it's HUGE LENS!! so in 135 format will have larger aperture lens than enable to shot with faster shutter speed.

135 format is develop on consideration of portability and fast response on field, out of studio use.

larger aperture is nothing associate with image quality, as all lens have best performance in middle open of aperture, If you ever read MTF graph of the lens. and shallow of DOF of 2.8 on 135 is far behind of medium format on F4 in same angle of view.

Larger lens and sensor in medium.large format is look for ultimate quality in enlargement purpose, like advertisement in size of building high, 135 system for more portability and flexible for outdoor and out of studio environment that I clearly mentioned before, but I can't see a strong evidence of 135 format have "quality" superior to medium format solely on quality issue, optically and digitally, that completely replacement over Medium Format.

multipass exposure =/= multiple exposure, studio Digital Back do exposures on same lighting, same setting and same suject on a very rigid, vibration free tripod or support for 2 or 4 times to get higher quality image.

I just clarify on not so precise and correct concept stated, be cool.
