Mamiya 300 mm F4.5 IF APO lens

[Bill Caulfeild-Browne]

I used to own this lens when I had a Phase One P45 and it was excellent on that MFDB.
Has anybody used it on the IQ4 150 back? I'm interested in getting a bit more reach than the Phase 240mm. I don't care much about corner resolution - this is for wildlife, not landscapes.
Any input welcomed.

I have one that I use often, but not on an IQ4150, unfortunately

To answer my own question, the Mamiya works just fine on the IQ4-150. I obtained a used one from my dealer. The extreme corners may not be as good as the Phase 240 wide open and it doesn't focus as close - but it's a bit lighter and does have the extra reach I wanted.

My standard test subject. ISO 50, 1/200 at f8.

Bill, nice shot. If you got that from B3K, it's my old lens. Had it for years but never got around to using it.

Here are two images taken a minutes apart with the 240mmPhase one and the 300mm Mamiya...Both images had my Mamiya 2X attached to the lenses using the IQ 150 back…manual focus of course as auto focus is not active with the 2X

Regarding the above post, obviously the Mamiya 300mm lens is the top image. I'm surprised the Mamiya compares favorably.

Yes, from B3K. They had two - I got serial #TC0185. I'm pleased with it.

I sold my 2X converter because I found it wasn't as good as uprezzing the 240 mm file. Seems it may degrade the Mamiya file as well!

Continuing to check out the 300 mm Mamiya on the XF/IQ4 150.

I own this lens and have not used it for years ever since I sold my XF kit.

I find myself reaching for the 300mm Mamiya, while leaving the 240mm phase one on the shelf…just don’t see a difference in sharpness

BTW..kudos to the folks on this boat…the temperature is barely 50 degrees…it’s blowing 25 knots and they have three sails up…I hope they have their winter woolies on

The Manual focus Mamiya 645 lenses are also fantastic. I use the 200 f2.8 APO and the 300 f2.8 APO lenses on the Leica S. The standard A and C lenses like the 300mm f5.6 and the 150mm f2.8 also give really good results.

I agree - unless you want the leaf shutter, the Mamiya is just as good.
