Thanks, my second review I have watched on this lens and really like the Art you can find or produce. Laurie. NZ. 😊

I really enjoy your photography videos

I mean... this shouldn't be such a surprise to people. Yes, most modern lenses are technically superior to most vintage lenses in terms of sharpness, bokeh, and color rendering. However, some vintage lenses offer something aesthetic that isn't measured so easily. It's like the difference between a CD and a vinyl record. The CD is superior in almost every way. The vinyl offers a certain aesthetic you don't otherwise get. Ditto with solid state vs tube/valve amplification.

Hello Simon, I'd really like to get into contact with you about a vintage Fujinon lens. The camera is a prototype, and I'm finding it hard to get information on the lens as well. Perhaps you could be of assistance! Please let me know if you're interested!

You must have got a good copy of helios, but pancolar carl zeiss jena 50 1.8 is somewhat better i think

Great video, thanks so much. By the way, I've always heard 'helicoid' pronounced "heli *KOID*" rather than "heliSOID" ... but no big deal.

I bought it because most sources did say this lens is surprisingly sharp and that its quality would be more suited for a lense 2, 3 or 5 times its price. "Only chromatic bla bla, well, but besides that". ... Here is the catch. I already have the 7artisans 35mm f/0.95, bothlenses for MFT. And for some reason my 7 manages aboration better, has sharper image quality and so on. But Maybe that's just me imagining things. So I watched some review videos of both lenses back to back and ... the Brightin looks like crap ompared to the 7. But How? In all these "Brighten is the best budget sub f/1 lens" they all had very good quality example images. But seems like the Brighten is just show and not much else. The Brighten looks more expencive but the 7 IS more expencive. The Brightin is a good example of "by cheap, by twice".

Subbed. I'll try it on my 44 got a few nice affects

Does anyone know where I can find C mount to Leica M and Sony E mount bodies?

This video caught my attention because I'll be retiring soon and I plan to get back into photography as a hobby. My hope has been to find a versatile digital camera for stills and video that will pair well with the Carl Zeiss lenses previously used with my Contax 35mm SLR film camera. After watching this video, it appears that there are plenty of options, which is encouraging. Now comes the task of sorting through the dizzying array of choices. It'll be fun if it doesn't drive me crazy. 😎

I have a couple of 5 cm Elmar M collapsible lenses, one is F2.8, and the other F3.5. I use them occassionally on my M2 and M3. Right now I am waiting for a IIIc and and an Elmar F3.5 L39 to be delivered. The lens has the modern aperture settings and from the photograph it seemed to be coated, but I could be wrong. We'll see how they perform together.

Nice comparison. I have the later f/1.8, which isn't radioactive, and it's a wonderful lens. I do have a question, though. How do you use these on a DSLR? Because of the flange distance, when I adapt mine to my Nikon, I can't focus farther than about 3m. I tried one of the "correcting" adapters, but it both slightly increases the effective FL, and somewhat degrades the optical performance.

Thank you.. very interesting video

Amazing video

I had an opportunity to pick this up at used place, for $60... But I was too busy researching if whether or not I should buy. Seller wasn't aware of the value. Oh, camera aquistion regretts. 😢

Id shoot architectural details with this. Things high up not normally seen in detail. That draws me

It is possible to make on without the donuts. It is also possible to make one with hexagons donuts. The tech is out there in telescopes, however they do not deal with donuts, because everything is to far to focus closer. That said, is clear that the charm of this lens is the donuts. Take a 1/4 bite of a donut for every donut said in the video, drink your preferred non-alcoholic beverage every complete donut eaten. Happy donuting.

It's an addiction sure, but by this point, it's either GAS or snorting Thorium glass powder.

We did you get the geiger counter?

Is this Jena Flektogon 35mm 2.4 Radioactive? Camerapedia only have Auto Not Radioactive. I see no other forum or video talking if it is radioactive. I see 3 Variant of this No Electric Text in Front (This Video) before the MC - MC Flektogon 2.4/35 The one with Electric text before the MC in the Front - Electric MC Flektogon 2.4/35 And Auto after the end of Flecktagon Text in the Front - Flektogon 2.4/35 Auto

Would the ones that are more radioactive fog film?

Excellent test!

Thank you for enlightening us. It's wonderfull when someone can express their experience and knowledge so succintly and clearly, on something both technically complex and subjective.

Fantastic work. It is a shame that you don't include cameras used in professional and art photography. Popular photography certainly drives the market and a great deal of innovation, but I feel that there's really a major part of the story missing by omitting those parts of the puzzle.

@Simonsutak can you make a video comparing the SMC takumar and the super takumar 35mm f/3.5 lenses? would be greatly appreciated!

Hi Simon is the Canon FD 50mm f/1.4 S.S.C. Radioactive? One result on google from forum Denied it. Camerapedia have NO Record of it. Could you test it and make a Video?

Late to the party, but is there a way to ACCELERATE the yellowing of radioactive lenses, and are there adverse effects to doing so? Like, it won't go critical or anything right? like i mean I'm single and all but like haha don't wanna diejustyethaha. Acquired a Canon FL 58/1.2 in super good condition and have been having alot of fun with it, but would love to have more of the vintage golden tint. Without dying of course. Haha.

This is cool, unusual, and informative! I hope this gets a lot of views. So here is my long comment for it 👍

How would you compare it to the RE Auto Topcor 58mm f1.8 ?

I do enjoy your intelligent and well-researched videos, and there is an unexpected bonus - we live in the same neighbourhood. It's fun trying to identify your exact shooting position when taking your pictures. And the fact that you like Pentax gear shows you have excellent taste.

For me, the Pentax Super A was the best-looking SLR ever made. It was also very functional.

A lot of the “digital optimisation “ debate is about diffraction limitations. It’s all misunderstood crap in my opinion. High quality modern lenses are simply more precise and better. But a good quality old lens will be good! Film look etc are statements made by people who don’t understand how to process a raw file. Use your old lens if it makes you happy.

Great video. I have all versions too. I bought that lamp on your recommendation and successfully deyellowed my SMC. Wow, what a difference!! It's by far the best lens (objectively) out of the bunch. It's more like a Zeiss lens now. The downside is it doesn't have as much character. The yellowed glass evidently affects a lot more than light transmission. My 8 elements version is still my favourite because it is special, but all versions are great. My recommendation would be to buy whichever good condition Takumar is cheapest.

Hello. I have a Helios-44M 2/58 that is extremely soft at all f-stops. The glass looks clean to me, so I was thinking of taking it apart to see if there was any obvious problem internally. Do you have experience with remedying this issue?

Are all Auto Takumar Radioactive? I see no information in the web

Amazing video! Thank you for the extensive tests! 👌🏻

I recently acquired two strange lenses that I had never heard of, a Komura Sankyo Koki 135mm f2.8 in M42, with 15(!) blades, and a Sonagar 135mm f3.5 in Minolta mount with 10 blades. I got them both at a camera club sale, $5 for the Komura and $3 for the Sonagar. The Komura is a bokeh beast, while being very small and lightweight. I have really enjoyed shooting with this lens. It really does rival my Pentacon 135mm f2.8 (Auto MC version). The Sonagar is unremarkable, but it's the best $3 lens I own. I did notice that there seem to be quite a few Sankyo KOHKI lenses out there, but mine is spelled KOKI, which I find odd. I didn't know anything about it when I bought it, although I do own a Komura Komuranon 820 80-200 f4.5 zoom that performs very well, and I assume that the Sankyo Koki is a much older lens. it has been a joy to shoot with.

Best 100 and 105mm lens review. Just idea I really enjoy your videos. Thank you

Thank you! Excellent review. Glad to learn of the Gold effect options on the K-1. Really enjoy that look. Was considering this lens in comparison to the FA 50mm 1.7 and now understand that they are different enough from each other.

Bought mine new in Poland in 1976. Still going strong!

What about at night though?

So many of your observations had me nodding my head. One thing to add to the Flickr algorithm is it rewards frequent posting (365 projects for example). There is definitely a legacy glass fan base that lives there. Your contribution in the form of lens evaluation is adding value to that community.

I am a Contax/Yashica Shooter since 1990, and i must say, i really *dislike* that brightin star as brand is just cloning the Zeiss package box design hereby - it's very lame, and cheap, too.

Have you looked at the sun lately? Here in Madison, Wisconsin, and in other places around the United States the sun flare has been an octagon except it’s like a honeycomb? there’s been a lot of speculation and conspiracy theories about it and why the sun is so bright white and why there is always a constant haze and all of the storms in the Midwest. I just wanted to know if you have seen any honeycomb flares. They can easily be picked up by phones.

Great review! Everything you need to know, thank you. I bought the original smc FA 50mm f1.4 this morning for my K5iis. Coming from Fuji, I am enjoying the SLR experience again, but it is jarring to be so sensitive at the wider end for softness, as my modern lenses are simply… sharp. However, I am trying to stretch myself and embrace the soft, as I’m a bit over the optical perfection that is synonymous with current lenses, causing people to spend more on diffusion filters than my lens cost me. I have found in my testing so far that a slight back focus can masquerade as softness, and that when focus is good, the lens is plenty sharp enough.

Didn’t Leica license this lens to Minolta in return for being allowed to use the Rokkor 35-70mm design for the R System?

Thanks. Many years ago I was thinking about buying one of these.When it was still on the market. I always been sorry I didn't.

I love the jokes and the abundance of sample photos!

Hi Simon, Excellent review. So, using it on a FF camera would give you say a ~40mm equivalent view with the darkened corners nipped off?

If this lens is attached to a mirrorless camera, is the camera still mirrorless? 🤔
