I found my C 45/2.8N was on par with my C 35/3.5N and C 55/2.8N lenses. I sold the 45N because I didn't need the intermediate focal length.

And I went the opposite route, putting the C 45/2.8N in my bag to "split the difference" in my M645 lineup.

I've also got my C/Y 35-70/3.4 which has plenty of micro-contrast in the similar focal range. But for shooting some subjects, the pleasant transitions of the M645 drawing style are more appealing than what the C/Y drawing style renders. Depending on what I'm shooting and what my objectives are for the image ... I may reach for either.

Rustybug- is there a big difference in IQ between the 45mm N and the regular 45mm (which I have)?

I also would like to know if there is a significant improvement in the 300mm ULD N versus the plain 300mm?

The primary difference as I know it is that the "N" versions have a slightly different coating that renders slightly more contrast. My 80/4 Macro is the regular (non-"N") version. I've never been compelled to get the "N" version. My 45 & 110 are "N", my 80/4 is regular "C", and my 150/2.8 is "A".

Another vote for the 120 A macro - its a super macro lens! My only nit is mine does not focus on infinity with the (guaranteed to infinity focus) Fotodiox Pro adaptor.

My only other Mamiya is the 35 C f3.5, which is sharp and has good colors.

Two sample pics - the C 35/3.5 is SOOC and most likely taken wide open since it was taken after sunset.

dbehrens- Nice work on the macro!

Anyone here has experience with a 55-110/4.5N? I have the 105-210/4.5 ULD and I love it! EVen though it is a zoom, it is quite sharp even at 210.

A test shot of 80/4 Macro with Mirex adapter. (f4.0, max tilt)
The 80/4 Macro is quite good at CA suppression.

Hello everyone. I've recently got a mamiya 80mm f/2.8 N and paired it with my d600. I love how smooth the manual focus is. I have a nikon 50mm f/1.4 AIS and a 24mm f/2.8 AF-D. I compare them with mamiya 80mm and I feel that mamiya is a little bit sharper. I don't know, maybe I cannot focus well enough with nikon lenses. My question is, If I get a mamiya 55mm f/2.8 N, will I going to be happy? Can we compare 80mm and 55mm in terms of image quality? Are they similar?

Here is what I got with 80mm f/2.8:

I find my copy of 55mm f/2.8 N not so great wide open as my 80mm f/2.8 N/L LS. Someone else wrote his 55 was the best of several different Mamiya focal lengths he tried, so it could be my copy isn't the best one. Hope this helps.

And yes, welcome to the forum!

Hi hemillion,

Welcome to FM.

My C 55/2.8 N is very sharp. So is my C 80/2.8 N. OTOH, I almost always use them at f/5.6 or f/8, for scenic and product photography. I generally use faster primes for "wide-open" shooting.

I like all of my Mamiya 645 lenses; C 35/3.5 N, C 55/2.8 N, C 80/2.8 N, C 80/4 N Macro, A 120/4 Macro, A 150/2.8, and A 200/2.8 APO. They're all very sharp. The C 35/3.5 N is probably the least-excellent of the bunch. It's very much on par IQ-wise with the Contax Carl Zeiss Distagon 35/2.8, which is a very fine lens.

Which of the mamiya 645 lenses would you recommend for a dslr? I currently have:
45mm f2.8
80mm f2.8
150m f3.5
200mm f4 N
105-210mm ULD

I am thinking about acquiring a 300mm f5.6? What ya think?


I'm just getting into Mamiya glass for my Nikon d3200 & am already very pleased.

I grabbed a 105-210mm "C" *non-ULD* for $80, & it's acceptably sharp. I posted a lens test of it using my LCD monitor, it resolves well, color rendition looks fine an ad-hoc, hand-held resolution test (link at bottom).

The only caveat about this 105-210 C *non-ULD* is its 2-touch focus/zoom & external focus. This is a non-issue for my uses, 2-touch zoom/focus is fine for that focal length. I've seen good results from other folk using the non-ULD 210 zoom. Altho a one-touch zoom/focus would be better for tracking moving objects, esp. birds, I'm just not ready to chase that price-point yet (c.f. Tamron adapt-all era SP f/2.8 300mm's were fine pro-level lenses of the day, but are rare & get bid up pretty fast on eBay).

As for the 300mm ULD, that *is* the one to get, especially the "N" (recent? new?) version, and is, in fact the very lens I grabbed today off of eBay for ~$200.

I've seen multiple comments from Mamiya shooters (both 35mm format & 645) that the "A" lenses are preferred over the "C", and that flavor is in the shorter focal lengths. Basically shop for the "A", "N", & "ULD" designations.

Since my first post, I have added
55 f2.8 N
300 f5.6 N ULD
80 f2/8 macro
55-110
75-150
A 120 f4
...
Of the bunch, the 55f2.8 N is the sharpest. The A120 is really sharp for macro only. I have used these lenses on my Nikons D90, D700 and Canon 5D, with cheap adapters from ebay. I am hoping to get the tilt and shift adapter soon...

You are gonna love the 55 2.8 N! Pretty sharp pictures you got there with the 80 2.8 N. I see you are from gator country.... Go 'Noles!

Burning questions!!!

1) How do you like the cheap adapters? I have just the one from Fotodiox & it was $45.

2) How do you like the 300 ULD?

I also picked up the 80 f/4 macro & likewise is truly sharp in macro, delivers 1:1 no problem ... but depending on focus range it seems to soften... (not sure yet).

Over on Dyxum's fora I found a big group hug over the Mamiya f/1.9 C N, others extolling the virtues of the 150mm f/2.8 A. What caught my interest were the consistent user reviews & blogs that Mamiya's C lenses have been consistently good (maybe one real dog out generations of lenses).

I'm happy with manual focus lenses for most stuff, but eventually I'll spring for an autofocus semi-long for wildlife photos - not sure which body though. It'll have to bear out that it's both sharp enough, as well as compatible with, a fully-purposed teleconverter ..

I've read more than once that stacked up against a 300mm w/ a 1.4x TC, many (most) 400mm & 500mm prosumer lenses simply fall short on resolution...

The C 80/4 Macro is a 1:2 (1/2 lifesize) macro unless you use the matching M645 Auto Macro Spacer (i.e. extension tube). Mine is sharp at all focus distances.

The A 150/2.8 is super. The C 80/1.9 is very nice, but I didn't like the way it handled specular bokeh, see

TY for sharing this, both are on the list. Decisions, decisions ...

I've only started using a DSLR a couple of months ago & now after some research & I'm in Mamiya lenses with 60+ lp/mm. Probably not your typical consumer path. Long story ...

I want to thank you for pointing this out. It appears that *if* the forward MAG Dial on the front is engaged & that the forward placement of the front lens element is increased by a couple of millimeters, lengthening the lens assembly.

My guess is that if this is done without having first having mounted the macro spacer *extension tube*, that the adjustment in focal length is probably enough probably to make it all go soft.

As to whether I might've fiddled with the forward MAG dial the other night, well, go figure.

Jim, I understand where you are coming from but I tend to see things the opposite way.

When a lens renders an image slightly differently to the next lens, even badly, it makes that lens a little more interesting to use and IMHO offers opportunities other lenses can't or don't. I see the 80/1.9 in this light because of it's harsh bokeh and this is the reason I like to use it (it's also quite sharp wide open, but with CA/fringing). It's harsh bokeh differentiates it from the pack which I think is a good thing. Those that don't want or like harsh bokeh should avoid this lens.

I've posted this before but it shows the 80/1.9's harsh bokeh quite well. This is with max tilt (IIRC) on a Mirex and wide open.
