2001年5月15日 · is that all mamiya TLR optics are single coated. This is also the. opinion of some tech. support folks at Mamiya America. It is not an opinion shared. by all photo.net users, however. It is true that the last series of. lenses have a different coating than the earlier ones, and I think. that these lenses are superior to their predecessors. the ...

2000年8月1日 · The Mamiya is somewhat more difficult to shoot handheld than smaller TLR's like the Rolleiflex, as it's bigger and heavier. I usually mount my C330f on a tripod and go from there. As for sharper, depends on the lens.

1997年12月5日 · Also interesting is to note that a test of Mamiya TLR lenses (chrome lenses - 65,80,105,135,180) made in the mid-60s by Modern Photography rated the 105/3.5 (tessar) better than the 80/2.8 from f8 to f11, among the best results in the test, so we can't say that the 105/3.5 (tessar) wasn't sharp enough!<br>

2012年4月28日 · The films involved were Fuji Acros and the enchantingly gritty Fomapan 200, both developed in ID-11, with scans from an Epson V700. For those of you interested in the full range of lenses for the Mamiya TLR's, I recommend the excellent pages put together on the subject by Dr.Robert Smith:</p>

2003年1月9日 · Hi I just got a mamiya c220 and love it. I need to know what size filters to get. I cant tell if it is a 46 or 48 mm. The lens is a black 2.8 80mm and I also have a 135mm. The filter rings look to be the same size on both lenses. Thanks for the help!!

2014年5月31日 · Although Mamiya 6/7 lenses are brutally sharp, any rangefinder is difficult to use with moving subjects. Mamiya TLR lenses, especially the later ones, are also very good, but remember they're all at least 15-20 years old, I'm not sure …

2023年1月4日 · The only confirmed radical change made to the final 'S' variant was cost-cutting of the upper viewing lens assembly: unlike all previous Mamiya TLR lens iterations, the upper viewing lens on the 80 S is a different, cheaper, incompatible design (quite possibly 4 elements) in a permanently fixed barrel that cannot be opened for easy cleaning (or ...

2020年5月29日 · Mostly the Mamiya TLR lenses develop this inexplicable thick chalky haze, often with evenly spaced streak lines that almost appear synthetic. An absolute mystery how or why this repeatedly manifests: with no focus helicoid, theres really no lube or other source material to outgas and form haze, other than glass and metal.

2020年2月9日 · ALL the Mamiya TLR shutters, whatever vintage or barrel color, react poorly to the old "flush it with naptha" trick unless they are disassembled down to the last micro screw beforehand. The traditional DIY method of taking the glass off and flooding the shutter in place, or using a moistened cotton bud, usually makes matters worse: much worse.

2005年7月29日 · I own one of the Mamiya TLR glass prism finders, and find that it produces a rather-dark view. It magnifies the focusing screen about 3x. The porrofinders that I tested seemed to provide a brighter image (surprise!), but only had (roughly) a 2x magnification, which I found to be useless for my needs.
