645 lenses, what does the * stand for?

And which 300 mm fixed lens is the sharpest. I am shooting with the 645n. Thanks

The star means it's a premium lens, sort of like canons L series. On film any of the 645 lenses will probably be good enough.

From memory, the * or "star" denotes that the lens was one of the higher end lenses.

Usually better optics, wider aperture, etc.


They still use the same system with the DA* lenses vs just a DA lens.

I could buy a used 300 FA* F4 for about $250 -300 more than I could pay for a 300 A F4. Ignoring the dollar factor does anyone have an idea of which would be the better lens for film? My crude understanding was that this A lens is very highly regarded and is a very sharp lens, but that the * line of lenses might even be better, even though in this case it is the FA * 300. If both are in good shape would I even be able to see a difference. Both are F4, IF lenses, and I could spring for the extra $$ if the FA* is sharper than the regular A 300 F4 lens. Thanks Norm

The 645 A 4/300mm is itself a * lens, and from my own experience, a very sharp lens too. Better than the K 4/300mm for example.
The downside is: it has no tripod mount, which I think the FA has. That is a considerable advantage.

The FA 5.6/300mm may be slightly less sharp, but is far lighter, so do consider that one too.

Re: 645 lenses, what does the * stand for?

While I have never tried the 300mm f/5.6, I do have the 300mm f/4 and I can tell you it is excellent and one of my 3 favorite lenses for the 645. (The other two favorites are the 35mm f/3.5 and the 120mm f/4 macro.)

I have both and would miss the 300mmF5.6. It's much lighter, has a shorter minimum focus distance. If I expect good light or have to walk miles the F5.6 is what i take.

I have the 300/4 SMC-A* and ist is a good lens on the 645D. Completely open a bit soft and low contrast, but this changes suddenly when going to f/5.6
The only drawback I see it is not really working well with the 1.4x converter. Pictures don't almost provide any additional details compared to a crop. Off course, again using the 645D. The converter works very well with the 200/4 SMC-A on the same camera for landscape (at f/11 to f/16), so I use the combination of 200/4 and 1.4x converter as light telephoto lens.

I have the A* 300 f4 and use it the 645D, K5 and the Q all with very sharp results.

Before I bought it, I asked the same question and looked at the FA version, in the end I felt I wasn't loosing any sharpness by going the cheaper A*.
