VX 125 机身(4'X5'单轨座机) 广州新世纪报价23500元 　 太毒了!!
可以买四个 VIEW 45CX

TO游虾

毒发了，请问那有买，多少钱啊？感兴趣啊！谢谢

yaw free,我的理解是：当调焦完成后，前后组俯仰或者摇摆不会使胶平面中心脱焦，也就是不需要来回多次重复调整，这对于提高拍摄效率大有好处！！！

VX125 or Arca F-C or Lihnof Master tech2000

Hello', Please, could anyone experienced post opinion on choosing one of this cameras? I intend to use it mostly in the field, but I like that it has capability of doing some still life studio work. Easiness and quickness to use and set up very important. Thank you very much for your time.

The Technika, although expensive and heavy, would be hard to beat as a field camera, but not really suitable for still life studio work.

Mario: I would vote for the Arca-Swiss. It is lighter than the Linhof, and a more expandable system than the Toyo. I use the F-Line Field (6x9 front, 4x5 back) and find it to be very quick to set up and it packs well in a backpack. I have the standard not the folding rail so that I can use longer lenses (300mm). The F-line 4x5 with the larger front standard will give you more rise, but also more weight.

The Linhof that competes with the Toyo and the Arca is the Technikardan not a Technika.

The focal length of your preferred close-up lens may affect your choice of camera. A bulky f5.6 180 mm close up lens requires 360 mm bellows extension to get 1:1 image reproduction. A compact f9 210 mm process lens is suitable for both close up and at infinity, but requires 420 mm bellows extension for 1:1 reproduction -- beyond range of MT 2000, but (with accessory), achieveable by Arca F-C. I do not know about

Mario, I have a Technika and a VX 125, both very good but with some limitations . Master: extremely well built, compact, but unfortunately no lens fall or back rise, VX: the most compact, light monorail, one bellows is needed for lenses from very wide up to 300 mm, excellent movements but not steady enough in windy conditions. You might read the reviews in the "Camera reviews" threads. I have not used an Arca, but I think it is roughly similar to the VX, with a bit more weight and two bellows needed to accommodate a normal range of lenses. More cumbersome rail though but nice Orbix axial tilt option. There is an other camera, some photographers highly praise: the Ebony SV45 U2. It seems that this camera is very stable, very well built and offers some interesting features such as the U back. It is compact and takes a broad range of lenses, although the use of a bag bellows is recommended for wide angles. It was a bit expensive and I couldn't put my hand on one to see how it felt when I purchased the Toyo, but on a similar price base and primarily for field work, I think I would have gone for that one. It seems to be OK in the studio too. Fair wind!

Arca Swiss F-Line or Linhof TK45s. For studio work a camera that is a yaw free design makes life much, much simpler, so that rules out the Linhof (which is still a great camera and if you prefer on axis tilts, that is the way to go, and as Bob S. will tell you, if you tilt the TK45s on its side it is then yaw free). Ifyou get the metric and and orbix options on the Arca you'll have a great field & studio camera.

Thank you very much for your postings, I think I'm getting somewhere now: at this time my dilemma is restricted to only two cameras: Toyo VX125 which sound very fast to set up (ideal for catching rapid changings in the landscape scene) and Arca Swiss FC which sounds more capable then the other, what stops me is their costumer service (I read some where about it),I feel a little insecure about that. Anyway what is the Orbix? I can't find any information about it, I can't find their web site also. Thanks again.

Mario,
Orbix is an optional (extra cost) front standard module for Arca-Swiss F line cameras and permits axial lens tilts. The standard A-S F line camera front tilts along the base of the lens board. Base tilts require a focus readjustment - lens tilts do not. I think Ellis is much more qualified to comment on the value of this and the circumstances where this may or may not be useful.

If you're interested in the Arca, you might consider talking to Jeff at Badger Graphic. Web site is http://www_badgergraphic_com. Click on Large Format, then Arca-Swiss. Prices at Badger are decent and Jeff knows this product. I'm a happy cust

Mario, check this website - there was a discussion about the Orbix a few weeks ago! Regarding "Customer Support" - I was one of the complainants, but once I got my Arca (after some "cruel" wait ;-) I must say I am more than satisfied!

Thank you Bob for asking that question. Please explain why linhof offers (offered?) yaw free Kardan cameras and i think you'll find your answer. More to the point YOU know the answers to that question. Linhof offers more camera designs than just the TK45s and and the Technika designs. Some of those designs are designed to be used in the studio and are yaw free.

Why is yaw free important?

arca swiss f-campact

ARCA SWISS F-Classic和TOYO VX125之比较数据：

指标-----------ARCA SWISS FC-------TOYO VX125
重量-----------3.3KG---------------2.6KG（厂家标称重量）
皮腔长度-------381mm---------------325mm
广角使用能力---75mm/再短要换皮腔---45mm

移轴能力F-CLASSIC稍大，但实际上VX125的移轴能力是足够的了。
其他：F-CLASSIC前后组水平移动为manual方式，VX125为geared方式；F-CLASSIC具备BASIC TITLE 30度，VX125不具备(此功能可通过芸薹倾斜代替）；它们二者的旋转和俯仰均为manual方式,升降和调焦则均为geared方式。

呵呵~~~~~~~~,放毒了！放毒了！！
乘机赚点工分^

游虾：机器还没到吗？

游虾的介绍比较周到。皮腔软硬非常适中，并非想象的只是软。有一定的抗风能力。用了不会后悔。

好机器,是为真正摄影师设计的外拍机.比林好夫好用.它的皮腔很软,用广角时不用换皮腔,广角的使用不收限制.轻便极了,让摄影师享受道摄影的乐趣.是任何4*5相机无法比的.
我现在有一套SINAR F1 一套LINHOF 我以后一定要买一只TOYO VX125 用来拍风光!

知道的一些来说说，机器还没到手。
1、该机器号称是field and studio大画幅相机，使用太空用合金制造，非常轻，但是刚度足够，适合野外和室内使用，重量仅2.6KG，折叠后尺寸302x220x125mm。
2、轨道采用伸缩延长结构，外附加2个30mm延长轨，轨道最长可以去到300mm，皮囊最长去到325mm，皮囊使用特殊的纤维材料制造，非常柔软，韧性十足。可以使用47~400T的镜头，58mm（包括58）以上镜头可以不用镜头凹板，也不用更换皮囊在该机器上正常使用，不过使用58mm镜头时，为了获得较大的移轴量和皮囊舒服些，推荐使用凹板，这是该机器设计最优秀的地方。
3、前后组移轴量完全相同。上升70mm，平移70mm，摇摆50度，俯仰50度。前后组微调焦各30mm，精密齿轮调节，上升和平移也均为精密齿轮调节，非常顺滑。摇摆和俯仰则是手动，并采用摩擦锁止，调节机构比45AII顺滑些。前后组摇摆和俯仰具有“YAW FREE”能力，与SINAR P2、X，以及CAMBO ULMITA类似。
4、所有配件包括皮囊和轨道均与TOYO G系列完全通用，可以更换250+250的轨道和485mm的皮囊或者更长的配件。
5、后背是标准的GRAFLEX规格，360旋转，可以在360度范围内任意锁止。
6、对焦屏采用TOYO独特的酸蚀刻毛玻璃，中心为菲涅尔透镜，毛玻璃屏上刻画67，69取景范围以及厘米方格，取景非常方便。

缺点：皮囊长度较小，折叠后虽然前后组框架能覆盖皮囊，但是皮囊仍暴露在外，需要小心保护，皮囊柔软，可能风大的时候拍摄不利。
