150mm vs 200mm | Manual Focus on 645N

Anyone have any experience with the A version of the 150mm and 200mm lenses? I shoot primarily landscapes (35mm and 45mm lenses), but I like to keep a telephoto around because you just never know. I realize that they won't be close to their 35mm equivalents, but I feel as if these are as long as I'll need for my 645N for my shooting style.

Thoughts?

I have both and if I don't need the reach of the 200, I'd pick the 150. It's very compact and has a very nice rendering.

IQ-wise, are they about the same? Obviously bokeh will be slightly off, but with CA, sharpness, etc.?

Edge to the 150 in every aspect.

I have most of the 645A system but not the 35 and 45. I also do mostly landscape and nature and my most practical walking around gear is 45~85 zoom, 120 macro, and then the 200 provides a good spread. I don`t think there is a large difference in image quality between 150 and 200 lenses usually stopped down for my purposes.
And yes, I would love to someday own the 35.

The A 150mm is really good, I was very pleased with it. Only real drawback is the minimum focus distance, which the FA has differently. I also used the FA 200mm, but preferred the 150 mm, which has just the edge. Don't know about the A 200mm, which has a different design.

As for minimum focus: 150-1.4 meters, 200-2 meters. That gives both a min. mag. about .15x and sometimes seems not quite tight enough, I know. The 80~160 focuses to 1 meter, substantially closer. For some subjects ext. tubes are the answer and the 150 works real well with them. The full auto set is usually available used on line.
