Welcome to the world of Pentax Takumar Lenses.

[β€’] Pentax Takumar Super Multi Coated Lenses with Sony A7II

I hope to grow this page with information on the Takumar series lenses engraved with the text “Super-Multi-Coated” on the front.

These lenses have been a new addition to my research which happened by chance after finding the 28mm for $25. If you were to start photography with a new mirrorless camera and don’t mind vintage glass the following Pentax lenses I recommend in primes are:

24mm F3.5, 28mm F3.5, 35mm F3.5, 55mm F1.8. My goal is to acquire the 85mm F1.8 and 135mm F2.5 as a complete set, review and test.

History of Pentax – Started with a camera manufacturer in Japan known as the Asahi Optical Co founded by Kumo Kajiwara. Takumar branding was named after the Japanese-American portrait painter, Takuma Kajiwara and he helped sell these lenses to the US market.

Super-Multi-Coated – The early Takumar lenses were made with single-layer coated elements and along the production line by 1971 Pentax upped their game with the introduction of Super-Multi-Coated lenses which have up to 7 layers of coatings. This attention to detail and production process corresponded with efficiency problems. Many professionals in the photography industry stand by the quality of these Pentax lenses often saying that Takumar’s were better than Zeiss and Leica.

Serial Number – Each lens on the front facing ring has an assigned serial number. There are dedicated websites to the serial numbers and production run info. Generally when I’m looking to purchase a lens I aim for the higher number lens i.e 6237348 is on my 50mm F1.4 instead of finding one with a lower number i.e 156234 because I generally find the lens quality is well and truly finessed after the first batches. Unless you pick up a one off by chance where the serial number is 001 or in top 10 which would be worth its weight in gold. Serial numbers are great in finding their history if you are a history buff.

Product Code/Version Code – Product Code or also known as “Version Code” are numbers engraved on the under side of the MANUAL / AUTO lock tab of each lens. i.e On my 28mm can be found with the number “43827” engraved.

Thorium coating – Thorium lenses are distinctive with a yellow glow or tinge and colourisation can be reversed by exposing to sunlight or UV light. Some people recommend an IKEA desk lamp to correct the lens. Product code 37800, 37801 and 37902 have the coating. Radioactive decay is debated across all forums. I have Canon FD lens with this design and I haven’t kicked the bucket yet from usage. If you do drop one and it shatters take necessary precautions.

πŸ‘“ Pentax Super-Multi-Coated Takumar 17mm F4 (43842)


[β€’] Pentax Takumar 17mm F4 Super-Multi-Coated

Known as “The Fish” by diehard Pentax users the 17mm F4 fish eye wide angle is an interesting lens equipped with three built in filters (( Y48 (Y2), L39 (UV), 056 (02) )) 90 degree focus throw, 6 Aperture blades with max aperture of F4 and closes down to F16.

Pentax made three versions in the fish eye but with the addition of the built in filter this makes the lens unique and special in my book. Filter samples below:

[β€’] Pentax Takumar 17mm F4 ( Filter L39 (UV) )
[β€’] Pentax Takumar 17mm F4 ( Filter 056 (02) )

For a Fish-eye lens it is small and very compact. Most of all enjoyable to use and would put a smile on anybody’s face. Photographs can be created with varying aspects depending on the angle you choose i.e By tilting your camera up or down for more distortion. Great for creativity and just set to infinity and click away with only worrying about exposure. If using one of the three filters expect exposure to vary greatly between them.

As for prices they vary to be expensive to low determined by condition. Watch out as the internals can be corroded but in my case the lens perfectly functions but may need a professional overhaul in the future.

I personally enjoy the fisheye distortion and perspective we often see the same landscapes and structures captured. A fisheye can turn the every day norm into something exciting and new again.

The lens is very small and if you compare it to what Canon produces it looks tiny. The important stand out feature is the all metal build quality where in today’s photographic world everything is plastic as this fisheye is luxury.

Review still in progress please come back.

πŸ‘“ Pentax Super-Multi-Coated Takumar 20mm F4.5 (43951)


[β€’] Pentax Takumar 20mm F4.5 Super-Multi-Coated

This 20mm is larger than the others has some presence and will draw your attention to the beauty of the build quality. Known and described as a “Rare Bird” for its rarity on online forums. 90 degree throw on the focusing ring, 5 aperture blades with max aperture of F3.5 and closes down to F16. The lens is still a short profile even when attached to the Fotodiox adapter.

Enjoyably compact for street photography and no way attention seeking to be seen. Focus is very nice and smooth rivals Leica lenses in this category and in my opinion better. I can pretty much set the focal length knowing the photographs will be in focus even at infinity with the adapter.

Sometimes it’s hard to describe a lens in terms of not trying to be technical without boring someone to death. I want to highlight lens characteristics a bit more in these reviews. This 20mm oozes lens character and has a subtle quality like a Leica lens without the extreme end of a large aperture you would find in a highly priced lens. Character I think I just have to keep saying that as the key word for this lens review.

The below photographs on first day of testing mid morning with the day becoming bright in dynamic range but don’t let that deter you from using this lens. As I didn’t have a sun hood some lens flare on other photographs typical of the build but that doesn’t faze me. Slight vignette again ever so slight on full frame. Clean capture very happy with this version. I think my challenge is to capture the right image and something special to highlight the capabilities.

πŸ‘“ Pentax Super-Multi-Coated Takumar 24mm F3.5 (43962)


[β€’] Pentax Takumar 24mm F3.5 Super-Multi-Coated

This 24mm is just slightly smaller than the above 20mm but has some decent presence. With a 90 degree throw on the focusing ring, 5 aperture blades with max aperture of F3.5 and closes down to F16. Extreme high quality wide angle all solid metal construction with very nice resolving optics design 9 elements in 8 groups. Only a little distortion and you have to keep in mind these lens were designed for film. Focus is very nice just like the others with a hidden surprise of the lens shortest focal length to subject is brilliant.


[β€’] Can you feel summer coming.

At 100% crop excellent results especially with the Fujifilm X-H1 which has been my go to lens/camera combination. Circular sun flare has a nice look sample below. Bokeh is subtle and soft and even elegant in the way it looks.

πŸ‘“ Pentax Super-Multi-Coated Takumar 28mm F3.5 (43872)


[β€’] Pentax Takumar 28mm F3.5 Super-Multi-Coated

The 28mm F3.5 is probably the smallest lens I have ever held in my hand at this focal length.

[β€’] Pentax Takumar 28mm F3.5 With Fujifilm X-H1 = 44.8mm

If you read my other reviews 28mm is my go to focal length and this 28mm Super Multi Coated Takumar is no slouch. With a 135 degree focus throw and 6 aperture blades with max aperture of F3.5 and closes down to F16 opens the door to leading the pack of a favourite lens (Earlier version F22). So what if the aperture is F3.5 this lens displays beautiful bokeh. The type of bokeh I call wishy washy in style and typical signature trade mark from in all the Super Multi Coated lenses. When you get the photograph right this lens is sharp with excellent contrast, colour and rendering. Little distortion and not enough to worry about correction. Also factor in softness in the corners at F3.5.

[β€’] Pentax Takumar 28mm F3.5

Some say a picture is worth a 1000 words. 28mm is a lens that can capture that saying. Its a journalistic lens of choice to help you tell your story. 28mm is no doubt a favourite in my book and a recommended lens focal length for any avid photographer. At this price point you would be crazy not to own a version of this lens.

I really look forward to some street photography to really extend the research in performance.

πŸ‘“ Pentax Super-Multi-Coated Takumar 35mm F3.5 (43572)

[β€’] Pentax Takumar 35mm F3.5 Super-Multi-Coated

This 35mm has a 135 degree throw on the focusing ring and 6 aperture blades with max aperture of F3.5 and closes down to F16. Extreme high quality wide angle all solid metal construction with very nice resolving optics design 5 elements in 4 groups. Known become sharper above F8. Recommended to use with a hood. Using this feels like a piece of man jewellery and a James Bond spy at the same time but this can be applied to all these Takumar’s.

[β€’] Pentax Takumar 35mm F2 Super-Multi-Coated

I have mentioned briefly that some Pentax lenses are radioactive and this is one of them. With a yellow tinge to the lens expect the performance to result in a very warm image and correction can be done two ways either in edit or put the lens under UV light for a few days.

πŸ‘“ Pentax Super-Multi-Coated Takumar 50mm F4 Macro (43912)


[β€’] Pentax Takumar 50mm F4 Super-Multi-Coated Macro

Macro photography starts with a lens and for $100 there’s nothing stopping you from capturing the unseen little things you walk past everyday. Non stop I have been testing this lens and by far its has to be my favourite out of the set.

[β€’] Cactus Flower

I have tested the lens wide open at F4 as you can see in the samples to low light studio work and flash photography product shots. What is there to fault in a superb built beautiful lens for $100. seriously you can not knock a product that would give you such joy for the value it represents.

[β€’] Macro Flower

Sharp at F11 has a fall off when used wide open at F4 typical of the design and in my opinion has the right amount of style in regards to contrast depth and blur.

No doubt from the time I finish this review the lens will double in value and at the same time add many many more images to my portfolio. Considering I have enjoyed using this lens much more than the two Canon FD lenses I have but the Pentax is special and added missing images to my portfolio. Truly enjoyable and in any bag should you make room for a macro.

[β€’] Pentax Takumar 50mm F1.4 Super-Multi-Coated

1964 the first Super Takumar 50mm f / 1.4 (V1) – 8 lenses in 7 groups (without thorium treatment)

1965 to 1971 the Super Takumar 50mm f / 1.4 (V2) – 7 lenses in 6 groups and have 6 Diaphragm blades

1971 Takumar Super-Multi-Coated 50mm f / 1.4 – 7 lenses in 6 groups 8 diaphragm blades (code version 37902)


[β€’] Selfie with Fujifilm

Photographs taken with version 37902 (50mm 1.4). Has a 220 degree throw on the lens which takes 4 turns with thumb and middle finger. A bit more work to nail focus. Has a retro soft look to the images even when shot wide open. Not a sharp lens quite soft. I’m not 100% convinced with this lens and so far prefer the other versions 1.8 and 55mm F2. The key to finding out which 50mm is to try them all. I wouldn’t necessarily sell this one but will keep as a complete set. Further testing next on the Sony A7II.

πŸ‘“ Pentax Super-Multi-Coated Takumar 55mm F1.8 (37104)


[β€’] Pentax Takumar 55mm F1.8 Super-Multi-Coated

There’s some discussion online which is the best 50mm Pentax produced. Personally I think it comes down to the photographer using each version some like the extra F stop and there’s a reason why I prefer the 55mm in this category for the focal length (55mm x 1.6 Crop = 88mm Portrait Lens). Both the 55mm F2 and 55mm F1.8 are up there as the best bang for their buck. Seriously great value. This 55mm has a 300 degree focus throw which is surprising against the 55 F2 which is about 30 degrees more. Both very similar except for the aperture difference but focus throw amazes me.

[β€’] Pentax Takumar 55mm F1.8 Super-Multi-Coated

Below samples show a beautiful milky fall off when shot wide open. Bokeh is just lovely and colours and contrast to my liking. Compare this to the Canon EF 50mm 1.2L and this lens really gives a new lens run for its money. Why on earth would you spend $1500 verse $100. If Auto-focus is what you want that’s exactly what you will pay for. Yes the convenience of auto focus.

πŸ‘“ Pentax Super Takumar 55mm F2 (37103)


[β€’] Pentax Super -Takumar 55mm F2

What is the best 50mm 1.4, 55mm F1.8 or 55mm F2 Pentax?.

I prefer the 55mm F2. On a crop sensor the lens becomes a 88mm and this focal length converts into a great portrait lens on APSC. Especially for value if you want a true 80mm in the 1.8 aperture range where prices will start $500 and upwards.

My version 55mm is tack sharp on focus with a lovely fall off bokeh. Little vignetting and ever so slight shows how shockingly good it is. 330 degree throw on the lens which surprised me compared to the others. No issues with the Fotodiox adapter unlike the 50mm Super Multi Coated 1.4 which didn’t seat too well but this 55mm F2 is perfectly married. Out of lens contrast is excellent along with colour which is a deep vibrance that needs no adjustment.

Taken with the Sony A7II Aperture F2, Shutter 6400 Sec, ISO 250. There is a difference compared to the Canon FD 85mm where the 55mm Takumar bokeh blur is much preferred washy, wavy and reigns as king.

Lets get straight to the point on this lens. “Everything you photograph will turn to gold” and this is probably understating how great the lens performs. Lovely lovely bokeh when shot wide open. 270 degree throw on the focus ring, 8 aperture blades with max aperture of F1.8 and closes down to F16. Extreme high quality portrait lens all solid metal construction with very nice resolving optics design 6 elements in 6 groups.

[β€’] Pentax Super-Takumar 85mm 1.9

Last Pentax Takumar added to my research. The reason for two versions in 85mm 1.8 SMC and this Super-Takumar in 1.9 can be used on a crop sensor becomes a 136mm. This Super-Tak is faster at 1.9 than the 135mm F2.5 version.

A very very very soft lens when using. No Super Multi Coated and will never be in the same league but it is what it is. Unless you like very soft images that look taken with Vaseline smeared over the front element I recommend do not purchase this lens. Images will be uploaded soon.

Recommended Adapters for Sony E-Mount and Fujifilm X-Mount

Fotodiox Pro M42-NEX Sony E Mount Adapter (Type1)

[β€’] Fotodiox M42 – Sony E Mount Adapter

This version adapter is important as the rear of these Pentax lenses have the aperture pin and two small tabs sticking out. So if you decide on the other Pentax lens’s please double check you get the right version adapter.

[β€’] Fotasy M42 – X Mount

Solid metal mount lens adapter allows M42 Screw Mount Takumar Lens to fit on Fujifilm. Very affordable at $12.13. Could be placed on all your lenses to save time. Build quality very nice.

Recommendation: Best to use lenses like these on a mirrorless as the probability of mirror slap can happen and ruin your DSLR. Other factor’s to consider mirrorless over a DSLR is that you have to shoot in live view mode and cannot enjoy holding the camera to your eye for a much more enjoyable experience. Mirrorless has added features in a digital viewfinder for much greater control with manual lenses. Such features have made photographers switch from auto focus lenses to manual because they are that easy and superb to use.

Note: Make sure you do your research and purchase from a recommended seller.
