55-110mm f/4.5 Zoom AF. Equivalent to 34-68mm in 35mm format. The 645 AFD lens system offers two ideally matched zoom lenses adding total 35mm format handling and flexibility to medium format quality. The AF 55-110 f/4.5 zoom covers the popular 35-70mm zoom range in 35, whereas the AF 105-210mm f/4.5 ULD is its perfect match covering a 68-130 equivalent range.

I would say this describes the comparison between the 105-210 vs 75-150. I have both, the 75-150 is quite sharp with my IQ180, the 105-210 sits in the closet. The 105-210 seemed OK (still not great) with the p45, definitely worse on p65, and pretty weak/unusable with the iq180. As with most zooms, some copies are better than others so you may luck out.

Hello Guys,
as i said i have bought a used Mamiya 105-210mm ULD lens. This lens is not very expensive and you could get it at ebay. I have an old Leaf Aptus 22Mpix. Yes with newer 60Mpix there should be a problem, but this is not my configuation.

I have tested it at my special "standart wall" and here are the results.

First with 105mm full picture. Then with f6.3 and with f11 at 100%:

เลนส์ตัวต่อมาก็ยังเป็น medium format ยี่ห้อ BRONICA เลยเอาข้อมูลเลนส์มาให้อ่านกัน
Bronica was originally unable to manufacture it's own optics and hired Nikon. The early cameras of Bronica were focal plane SLR cameras such as the Bronica S2, C2, EC, etc. offers a unique optical design.
Unlike more complicated leaf shutter lens designs, these Bronica lenses do not require built-in shutters or focusing. The lens mount can also attach in three different ways with a large bayonet, small bayonet and a 57mm screw mount with a 1mm pitch. This made it easier for manufacturers to easily produce many different types of lens heads that share the same focusing module. This also made it easy for many companies to manufacture automatic or preset diaphragm modules with built-in focusing to attach to an existing lens head design not originally made for the Bronica. This is also great for making, adapting and hacking your own lens.
Nikon decided not to manufacture lenses for Bronica, so the company decided to produce their own optics under the brand name Zenzanon. This situation led Bronica to have a very low supply of the standard 75mm lens when they were to announce the newer Bronica EC series of cameras. Alternatives were needed and a 80mm f2.8 MC Zenzanon by Carl Zeiss Jena DDR was produced. A variety of different Zenzanon branded focal length lenses were made as the supply of Nikkor's decreased.

Strengths:    Colour ballance is excellent and very sharp from centre to corners. Image contrast is high due to the lens very good coatings.

Weaknesses:    This lens is heavy. The ability to focus closer would be usefull

Bottom Line:   
This is a fine performer with image quality equal to the zeiss 150mm but the Mamaya 150mm trails a little behind the Zenzanon. The 150mm fitted to the body with an AE prism and speedgrip is very heavy even using the neck strap, holding it by the speed grip gets tiresome after a while.

As indieated by the designation "S", the S-Planar T* f/5.6-120 mmis
a speciallens. Contrary to the usual taking jens whieh is optimally
eorreeted for large objeet distanees, the S-Planar* is optimally
eorreeted for close-range photography. In view of this property the
jens is ideally suited for special close-range work such as drawing
reproduetions and teehnieal subjeets where the standards of image
quality and freedom from distortion are mueh higher than for pietorial
photography.
The eorreetion of the S-Planar T* is relatively invulnerable to ehanges
in image seale. It ean therefore be used sueeessfuily for distanee
shots, too, but should be stopped down somewhat further than a
"normal" jens of eomparable foeallength. For close-range
photographs under 0.95 m adapter rings or a bellows extension
should always be used, as the use of Proxars has an unfavorable
effeet on the S-Planar's T* eorreetion.

Wonderfull lens - even mounted on a crop camera. I use the lens on Olympus (E-30); meaning that I have an adaptor from 645 to PK - and an adaptor ring from PK to Fourthirds. A bit of a way; but the lens is worth it.

I have written a review in English of this lens (and other lenses)

Cons:        front heavy, focus creep
Sharpness: 8    Aberrations: 8    Bokeh: 8    Handling: 7    Value: 9    Camera Used: 645N   

I picked it up on a whim from the junk bin for 6,500 yen. I prefer primes but at that price decided I could take a chance. I've only shot three rolls thru it but am pretty pleased with the results. But it sure is heavy! And the balance is extremely front heavy. My right hand aches after every roll! And I think the heavy front elements combined with the smooth and light action focus ring are what leads to the focus creep. Zoom ring is plenty stiff so no zoom creep but the focus ring moves to MFD rather quickly when the camera is dangling around my neck.

But the great thing about this lens is the range. The 645 A-series lineup has a big hole between 75mm and 120mm. And the 120mm is big and bulky too so in practice it often ends up being a 75mm to 150mm gap. This lens covers that range beautifully. The other option is using the 67 adapter and the 90mm and 105mm, both of which are excellent performers but the range of this zoom really makes sense, unlike the WA zoom which is totally redundant with the primes

Pros:        Well built, weight, size, sharp, natural color
Cons:        none
Sharpness: 10    Aberrations: 9    Bokeh: 10    Handling: 10    Value: 9    Camera Used: K-5IIs   

I used this on my K-5 with a 645 adapter and I believe this focal isn't 120 anymore but really doesn't matter to me.

I take this lens out a lot and take whatever I find right and it delivers a lot of fun and great photos as all other 645 lenses do. I have a 75 f2.8/35f3.5.

I like to mention that, may be because of the weight of this lens balance so well with my K-5 which gives a very confidence pressing on the shutter resulting ultra steady photo capture.

Here is a handheld snapshot by a 50s old man, me, 1/5 cropped from the original photo. It is amazing.

Pros:        Image quality, size and weight
Cons:        Lack of AF?
Sharpness: 10    Aberrations: 9    Bokeh: 9    Handling: 10    Value: 7    Camera Used: 645D, Nikon D800   

It has only 4 elements but performs impressively.
I rated 10 because I couldn't find any negative part.

Sharpness is nice despite the fact that it has only 4 elements. On 645D and used in landscape, even F3.5 ensures top notch sharpness if focused correctly. Initially I had some difficulty to focus precisely when the lens was combined with 645D; the focus was somewhat foreground when I felt it was on.

Aberrations are well controlled; I actually can see longitudinal CAs between F3.5 and F5.6 in high contrast part, but it is minimal. Besides CAs, there's nothing I should mention.

Bokeh is smooth. At wide open, vignetting (fall off) causes not circular bokeh, but it doesn't matter for me.

Handling is really good. Small and light weighted, so quite easy to handle.

Value was little bit expensive though both appearance and optics are so clean; also it should be noted that FA 150/2.8 costs more!

เลนส์กลุ่มต่อมา ถือเป็นอีกหนึ่งทางเลือก โดยเฉพาะแนวมาโคร  นั่นคือ ENLARGER LENSES
แล้วเจ้า enlarger lens นั้นมันคือเลนส์อะไร  มันก็คือเลนส์ที่เอาไว้อัดภาพ ขยายภาพตามร้านถ่ายรูปนั่นเอง
wiki; An enlarger is a specialized transparency projector used to produce photographic prints from film or glass negatives, or from transparencies.
enlarger lens -ข้อดี 1  ราคาถูก พอหมดยุคฟิล์ม การอัดรูปด้วยระบบdigitalใช้software ไม่จำเป็นต้องใช้เลนส์ชนิดนี้อีก จึงโดยขายทิ้งออกมาใน ebay มากมาย ราคาหลักร้อยบาท
2 เป็นเลนส์ที่ออกแบบมาให้ชัดทั้งภาพ ขอบถึงขอบ เหมาะกับมาโคร
3 ส่วนใหญ่เม้าท์ M39 หาadapter ไม่ยาก
4 การนำมาใช้งานต้องดัดแปลง ซื้ออุปกรณืเพิ่มเติม
ข้อเสีย 1 ที่ตัวเลนส์มีแต่ช่องปรับรูรับแสง ไม่มีชุดโฟกัสเวลาใช้งานอาจต้องหาชุดโฟกัสมาใช้     ถ้าหากมีbellow ก็สามารถนำมาใช้ แต่ใหญ่เกะกะ  อีกทางเลือกก็คือ helicoid tube ซึ่งก็คือ tube ที่หมุนแล้วยืด หด ได้    2 รูปร่างไม่สวย         
ตัวอย่างการนำมาใช้งานครับ
enlarger len ที่นำมาลองคือ HAMA MAKRO 75mm f3.5 mountM42
ใช้กับ helicoid tube สามารถเลือก ความยาว ยืด หด เท่าไร เลือก เอา M39,42ได้
มาดดูกันครับ
