點解哈蘇唔出 X-Pan D?

如題，肯定有市場...

乜唔係send比哈蘇咩.?
呢部係xpan噃!  
又唔係TX-2.

XPAN都係FUJI 幫佢造! 佢自己都唔識整!!!!!!
你都過左嚟啦!!!!

一定好很貴！但拉長cmos 唔難！

唔使 24x72 full frame，可以 18x54 (1.3x crop)，只比 FF 大 12.5%，鏡頭設計時可以用更大光圈添

可以Under 10k ma?

視乎市場訂位，如果是與M系競爭的，一機一鏡10k下有市場

加上24/4.5, 35/3.5, & 70/4 lenses (equivalent to 32mm, 47mm, & 94mm in FF)，肯定非常吸引！

可以用柯達 CCD, 18mm x 49mm (原本是 24mm x 65mm)

其實唔系無可能架...

Good idea

引死人啦，你應send e mail 俾fuji

大家咁話.左右逢源.一雞兩味.左顧右盼啦.

我曾幾何時以為Lunar會係兩塊 sensor 黐埋的 xpro1 變身，好明顯我好wishful !

似乎開發成本比一般的 APS-C 或者 DC 貴。軟體方面，影像的處理要否特別處理？

鏡頭方面，18mm x 48mm sensor, image circle diameter = 51.2mm

Comparing with FF 24mm x 36mm sensor, image circle diameter = 43.2mm

Medium format 33mm x 44mm sensor, image circle diameter = 55mm

To keep the sizes of the lenses small will be a design challenge.  Maximum aperture will be unlikely to be large, say around f/4 max.  Autofocus may take up some space.

Also, focal plane shutter design may have to be different.  Max shutter speed may have to be lower.

As to image processing, I don't see so far how different internal software would be required.

我的想法是比較 out of the box 。

這樣的設計有幾個好處。

分分鐘，用上兩塊較細的 sensors ，成本可能還要便宜一點，但要用上影像合併。

而且，不用「浪費」了多餘的 Sensor Area ，雙 Sensors 設計還可以減少機身的尺寸。

我諗sensor有邊位不能capture image，所以兩塊sensor泊埋，用software合併未必可行。所以都係要從hardware方面入手。

講到最後，hasselblad邊有錢做R&D吖。

Hasselblad only does re-brand Sony now.

Need to ask Fujifilm whether they wanna do it. Hahaha

The more I think about it, unfortunately the more it appears that there will be no Fuji X-Pan D in the near future.

It seems that both Fuji and Sony are now struggling with the acute angles of incident rays from wideangle lenses to the far edges of fullframe sensors.  The problem would only become worse if the sensor is further elongated.

Besides, stitching digital panoramas nowadays (using iPhone) is much easier than stitching films (using Arca-Swiss precision ballheads and view cameras) in the old days.

However, if one is eventually announced, I think I'd be very interested!
