I found one set of X7+WONDER+MC50/1.4 in yahoo auction.
All of them seemed clean and without problem.
The price is :15000JpYen(About 1000RMB).
How do u think about it?
Help me.

多谢指点,明白了不少。
说实在，俺对老机器所知非常有限，
直到最近很想添一台配标头的手动机时，
才发现选择面太难定，陈年老物门派花样
只比现在多，有些又很难找到相关资料，
更难确定其性价比等。想买时又犹豫配件
之类的怎么配。。。。现在暂定的目标是
钱多:F3HP/NEW F-1
钱少：SRT SUPER/KONICA C35?
都是1.4或1.7的亮玻璃，多好玩的玩具呀。
看来在俺购买/试用期间免不了要叨扰各位，
呵呵。

------------------

Cameraguy, I have no idea about these two pent&koni models. If you are
interested in minolta, I recommend XD or SRT super, the latter is a machanical one with mirror lock up which can not be found in most of the minolta models. Canon had a very interesting EF body, made in 1973, electrical and mechanical hybrid controled shutter, just like canon's flagship New F1. shutter from 30 second (very rare in old cameras) to 1/15 controled electrically, 1/30 to 1/1000 controled mechanically, which means it can work without battery. The EF has all functions classic SLRs should have except changing viewfinder. The construction looks the same as old F1, a real tank. Were not I already have too many minolta junks, I'll certainly get one as a toy. recently I chased several EF on EBAY, it is possible to get a good body with standard lens for less than 150 US$.

MORE QUESTION:
I want to buy a manual camera with 50mm/F1.4-1.8,really tired for
choice them in internet.
Can u give me adv about it?
Now I have two objects:
(1)PENTAX SV+55F1.8+200mmF4(it seemed nearly new goods)
(2)KONICA T3+50F1.7+135mmF3.2+2X TEELPLUS
price of each about 1800RMB,how about them?

I SEE.
Thank u,XITEK AND DKDK,thanks a lot.

X7以前我一直没搞清是个啥东西，前不久才搞到一份日文1983年的美能达产品
目录，上面都是当时的日本市场的型号。单反机共有六个：
X1-motor   294，000日元
XD-S        89，000
XD黑        84，000
XD白        78，000
X700        63，000
X70         52，000
X7黑        44，500
X7白        39，500

由此可见X7是个奇怪的特例，不象美能达通常做的把带7的型号定为中高档机型，
而是当时最低档的型号。从外观上看X70象X570，黑X7象X300，最怪的是白X7外观
与黑的不一样，握持处没有突起，象XG系列，这个X7只能用G型卷片器，不能用MD1
马达。
所以我跟XI兄唱个反调，别买这个东西，当初我买黑色XD7带50/1。4和卷片器也
只要150美元，和这套X7差不多，可厂家原价可差了一倍。目前在EBAY上100美元
出头买个XD11并不难。
