A Mamiya 645 80/2.8 N probably is a better option for 80mm. You can get one from KEH.com for $60-70.

welcome apaddy

some copy&paste from slrlensreview
=============================================
Canon APS-C: Mamiya 645 80mm f/2.8 N showed very solid performance in the lab. Center image quality is already pretty good at f/2.8, slightly improving with stopped down aperture, and peaking at f/4. Border quality is also very respectable in general, with slightly better results in the f/4-f/11 range. The overall results are pretty balanced, with no major performance gaps between the center and the borders. At its peak (around f/4), the lens is capable of producing outstanding 19in prints. In the f/4-f/11 range, the lens would be able to produce decent 24in prints. Conclusion? Overall performance is outstanding - the lens shows resolving capabilities that would easily put it into the top half of all primes tested so far.

Alternatives

Assuming you're looking for a standard prime for your Mamiya system, you are limited to two alternatives: Mamiya 645 80mm f/1.9 and Mamiya 645 110mm f/2.8. Both of these lenses are commonly available, but are slightly more expensive then 80mm f/2.8 reviewed here. If you are using Mamiya 645 AF or AFD series system, you can also include the AF version of 80mm f/2.8, although I'm not sure you will be gaining much in performance since both lenses implement identical optical formulas. You can also try adapting other medium format (or even large format) lenses to your Mamiya system. Carl Zeiss lenses for Hasselblad come to mind first and here you could explore Planar T* 80mm f/2 CF and Planar 100mm f/3.5 C primes. Both of these lenses are priced much higher then Mamiya's standard lens. Finally, you can try out Pentax 645 smc A 75mm f/2.8 (or its newer FA version), which offers excellent performance at a very reasonable price.

Recommendation

Mamiya 645 85m f/2.8 shows a lot of promise. While it is not strictly speaking the ultimate champion when it comes down to raw MTF50 results, it shows enough punch to make it an interesting choice as a medium telephoto. However, the main appeal of the lens is its price/performance ratio since it stacks up very favorably against many much more expensive lenses from different manufacturers. While I don't mind occasionally paying top dollar for a really good lens, I like good bargains (and I'm sure you do too) and Mamiya 645 80mm f/2.8 N seems to be one of the best bargains these days. Keep in mind that for ~US$100 (including a generic adapter) you will get a well performing lens. If you decide to add a tilt/shift adapter, you would get a setup that would save you $$$$ when compared to native tilt/shift lenses from Canon/Nikon etc. I'm getting carried away here a little bit - the review does not cover performance in the tilted/shifted modes, so it would be too premature to claim that the lens would be a viable alternative to a native tilt/shift setup. But there's a promise and given time (sometime in the future), I will try to do a test of the tilt/shift operations as well...

The 150/3.5 is a "good" lens, and the A120/4 is quite simply put a lot better than the famous planar 120. The 120-macro will though be a lot more expensive, it's hard to find good copies for less than 300$. But it's one of the few "close to perfect APO" macros out there.

The better one in the 150mm-range is the 150/2.8N, but that's also a bit more expensive - think in the 250$ range for a bargain. I have a hand-held full-size sample here:

http://ezpicshare.com/images/dsc21112ic.jpg.

Very little postprocessing, and some underexposure to avoid blowing the yellow seed-stems (name??) and the brighter parts of the petals (late noon direct sunlight) - but you can see the corner-to-corner performance at F/4. There's slightly more corner softness at F/2.8, but still a very good performer - better than my 70-200VRII on the D3x. Used with an Sony A850 in this shot.

This is an ~50% scale sample of the 150/2.8 at MFD:

I'd recommend the Mamiyas, even though only a few, more expensive lenses are truly "world class" - the 120/4A, the 200/2.8APO and the 300/2.8APO - most of the rest of the range are bargain finds. I'd stay away from the 55mm-lenses though - there are enough good offerings in the 50mm-range outside of the 645-MF range of lenses. Unless of course you want tilt/shift... Smile

Welcome apaddy!
Great to see people from China can log in here Very Happy

I am a Chinese too, if you have any problem with translation, I might help Wink

although mine is not that good too.

Yes, the price of adapters in China is much cheaper than anywhere else of the world. I think it is because the manpower is cheaper. But the quality control is only up to the craftman. I think you can find some very experienced guys who make good quality adapters by searching in www.xitek.com or www.fengniao.com.

Yes, the price of used lenses are much higher than other countries, especially when you come to the famous brand like CZJ and Leica. IMO it is due to lack of access to ebay and other foreign used stuff websites.

I am not familar with the mamiya lenses, but according to the review, seems like it is a good way to go. Did you have a look at this:

and

Seems like it has very good performance.

I don't really know how good the CZJ P6 80/2.8 is. I didn't read much positive things about it.

If you get a Mamiya 645 adapter you get access to the superb 120/4 macro. But there is also a CZJ 120/2.8 macro, but that will be a heavy lens.

Some nice images from the Mamiya 80/2.8: http://www.fredmiranda.com/forum/topic/882423/19#8618598
