First try in close-up mode below : 0,5X magnification, 1/80 sec @ f/9.5, ISO 800, handheld. QUITE SHARP ! .
0,5 X magnification, 1/200 sec @ f/8, ISO 1600 .
Finally, justice for this excellent lens below, 1/250 sec @ f/8 :
.
I "misplaced" (understand "lost") my LSC 1:1 adapter but I must admit 0,5X is enough to make amazing every day close-ups with the lens alone.
If I need greater magnification, I simply use my 645 Auto Bellows and the '67 to 645' adapter with it, in autoexposure Av mode on the 645Z. . OPTIMUM APERTURE : f/8

I really wanted a macro lens and this one is perfect. Wish I could find a user manual.

| Pros: | Very sharp and 1x magnification. | | Cons: | Short film to subject distance makes it hard to use outdoors with the LSC. | | Camera Used: 6x7, 67 and 67II

The 100/4 macro is the only true Pentax 6x7 macro lens, as it’s capable of 1x magnification with the “Life-Size Converter” LSC or 0.5x without the LSC. The older 135/4 macro can only achieve 0.32x magnification without extension tubes.
Usage:
The 100/4 Macro is a bit of an odd lens. Its front element is recessed in a funnel and has a 49mm filter thread at the bottom. This is where the lens hood or 49mm filters screw into. If you are using the LSC you remove the hood and screw the LSC into the 49mm filter thread, then you screw the hood into the top of the LSC. You can also mount 77mm filters onto the top of the lens hood. The lens has two distance scales, one when using the LSC and one when you are not. Confused, refer to one of the later Pentax 67 “Interchangeable Lenses Operating Manuals” for more information.
OUTDOORS: The 100/4 macro is not the easiest lens to use outdoors, especially with the LSC attached. The subject to film distance is so small (inches/centimeters) that you will block a lot of light falling on your subject. Also to get the proper DOF you will be using slow shutter speeds, so hand held shooting is out and MLU is required. This also makes it very difficult shooting moving subjects, such as insects and wind blown flowers. Using a tripod will fix some issues, but maneuvering one into position that is strong enough to support a 6x7 body & 100/4 is also going to be very hard.
INDOORS: For me this is where the 100/4 macro shines. In a controlled environment using daylight colour temperature lighting, I can get close enough to the subject using a tripod, MLU, slower film (100 ISO) and very slow shutter speeds. If you own a Pentax 67II, one of the “bright” telephoto/macro screens will help in focusing.
FILTER: As previously mentioned you can use either 49mm or 77mm screw in filters. You can’t use Pentax 6x7 77mm bayonet filters on this lens.
CASE: The 100/4 macro comes with the S90-160 soft case and the LSC has its own small soft case. The S90-160 has room for the lens, hood and LSC case.
HOOD: The 100/4 comes with the metal screw-in MH-RB49 hood.
Summary:
I can produce brilliant shoots indoors with this lens and it’s extremely sharp. Getting 1x magnification without extensions tubes is also great, as the TTL/AE metering will work while the lens DOF lever is in left the “AUTO” position. The only real issue with the 100/4 macro is the short film to subject distance, this is mostly due to the shorter focal length of the lens and the higher magnification achieved. Ideally the FL would have been 200mm, but never the less this is a truly excellent lens.
Price: I found my 100/4 in the used section of a local camera store and it cost $500.00CDN. It was in EXC+ condition and came with the hood, LSC and LSC soft case. I had to get the S90-160 lens case separately.

This post is just to add to what has already been said about this lens.
The main part of this lens is 6 element Double Gauss that looks similar to the 90mm f/2.8 in cross section. The life size adapter is a 3 element (Cooke Triplet ?) that looks to be an apochromat (corrected for 3 colors), which is common as the front group on telephoto lenses. This degree of color correction will be an improvement over using a screw-in achromat.
This recent design could easily be used on the 645D as an alternative to the more expensive 90mm ED Macro that was just released.

This is my favourite lens on my 67II. Sharpness and the bokeh it produces are just stunning, even on the 645D with adapter. It is by far the best lens I ever bought.

| Pros: | razor sharp, takes both 49mm and 77mm filters | | Cons: | trumpet shaped lens hood is unusual | |
The images this lens produces are EXACTLY why I bought into medium format in the first place. Can't imagine a sharper, contrastier lens. It's so stunning to view the chromes on the light table! Ordinary macro work won't stand up to 30x40 enlargements. No one can believe the 30x40's are from a 6x7 Macro lens and not a large format system. Even corner sharpness holds up quite well.
My initial fears about the standard multi-element life-size converter were unfounded. The lens reaches half life-size without the converter and comparing those shots with full life-size shots indicates almost no difference. I still can't believe how well the converter works. Add a 77mm Canon 500D multi-element close-up lens to the front of the "trumpet" and you get appx. 1.5x life-size with marketable sharpness and color rendition. This set-up has rendered my extension tube set moot. 1.5x in medium format is almost unheard of...
This lens also serves as a ridiculously sharp normal lens. It's bigger and heavier than the 105 (which is also sharp), but this "new generation" Macro model gets my vote based on imaging beyond belief. By "new generation" I'm referring to the fact that this lens was developed and released around the same time as the 67II--both very recently in Pentax 67 terms.
I pretty much put my 35mm system on the shelf for 3 years after shooting through this lens.
