      PS: I still think you need to do a full review on the Auto Sears/ Auto Rikenon 55mm f1.4 lens. Not very sharp wide open but the colors, the bokeh and the overall feel of the shots it produces is just magical. Lots of pixie dust right there :)

      Yes, those lenses are excellent for magical bokeh. I own the Mamiya/Sekor 55mm f1.4, a lens that is identical (I believe) to the Sears and Rikenon (and a few other Tomioka made 55/1,4 lenses). I agree with your description 100%. I also own a Cosina Cosinon 55mm f1.4 with very similar characteristics. Your comment encouraged me to take out and use the Cosina this morning.
      I've been thinking about reviewing the Cosina possibly versus the Mamiya/Sekor, as the Cosina is the only lens of this type that is not radioactive, and may appeal to more people. If I had more time I'd definitely do that review right now - but time seems so short at the moment.

      the 5cm f/2 being a Double Gauss design (slightly different between the "S" and "non S" version, but still) should have a nice swirl to it. Love someone mentioning any LTM lens, I always say it's an untapped treasure trove of lenses.

      @sander9t 6 днів тому +2

      Topcor-S 5cm f2 LTM (V2-V4 sharing the same 6/4 optics) is currently my top 3 favorite vintage lenses. Wide open the center is so sharp that I haven't found one vintage that is sharper (e.g., Summicron Rigid, Prominent Ultron, Zeiss Ultron "concave", Nikon/Canon's nifty fifties from the 70s) but the sharpness drops off very quickly off the center. The bokeh is smooth in the center but gets swirly quickly off the center. Another trait is that the lens produces a strong 3D effect unlike anything else - it is a combination of gray tonality on the subject as well as the elegant transition from in to out of focus areas.

    Hi Simon I have 2 versions of the 58mm 1.8, the RE Auto & the older Auto Topcor. As far as I can tell the older version is sharper. I also have the 20mm f:4, 28mm f:2.8, 35mm f:2.8 50mm 1.8 &135mm f:3.5. They are all great lenses. The 35mm was recognised as one of the sharpest lenses of its time which I can verify from my shots. Of all the lenses in my collection the Topcors are the one's I will never part with. Thank You for the informative video's!

    Thank you for a wonderful comparison between two great lenses. I agree that the 58mm f1.4 has the “feel” of a great lens, but I’d also agree that nailing the focus at f1.4 can be a hit or miss proposition (especially with my eyes). I haven’t used the f1.8 but now I’m quite intrigued to see how it compares with some other f1.8 lenses from that era (such as Minolta, Takuma or even the Pancolar).

  • @cvijax
    @cvijax 8 днів тому +1

    Thank you for this review. I am the one of those hooked on Tokyo Kogaku lenses. From technical point of view your review is very accurate. True, 1.4 is one of those lenses that are more difficult to use (but I have difficulties with all f1,5 fifties and faster). It takes a lot of dedicated use to tame it. But, once you know it, it does produce magical images. All RE Topcor lenses are extraordinary and where quite advanced for its time, particularly 35mm and 25mm. The 85mm and 300mm f2.8 are very rare and legends on its own (proce is out of my leage thou).
    I agree with @qingyunwang3802, Topcor-S 5cm f2 is the other one legendary Topcor 50mm lens. I like it better than f1.8 version.
    Even cheap UV Topcor lenses are optically quite good, but very unusual mount and much lower mechanical quality make them quile less desirable.

    6 bladed bokeh really used to bother me, to the extent that I avoided buying lenses with 6 blades. Now, it doesn't really bother me at all but I do try to avoid specular highlights in stopped down images, a different approach compared to using lenses with many more blades. Having said that, the Topcors do a better job than most 6-bladed lenses in producing quite pleasantly rounded hexagons up to f2.8.
    Rubber focus rings were innovative for the early 1960s, Topcon being one of the first to use rubber grips (Kilfitt being the first, I believe). Unfortunately, rubber technology wasn't quite up to the task in terms of longevity, although some copies of the Topcors fair far better than others, possibly down to storage conditions.

    • @KNURKonesur

      I skipped over the number of aperture blades bothering me by just using my bright vintage leneses wide open and just going with it :P
      Also with a bunch of old lenses the whole optical block is in one metal housing that sits inside a helicoid and body of the lens, so you can build your own "shell" if you're willing to sacrifice some of the asethetics of the original lens.

    • @Simonsutak

    Nice comparison. It seems like the f1.8 is probably, most of the time, the better lens. I have similar thoughts about my Pentax M series 50mm f1.4 and f1.7. I only grab the f1.4 lens when shooting film so the wide open sharpness reduction isn't as noticeable and I know I will want the extra light. Otherwise I always go for the f1.7.

      This is universally true of any brand. The slower lens will be better, and the corners will clean up faster due to less residual aberrations. The performance will be better wide open. The f/1.7-f/2 version generally are technically better than the f/1.4. Although, some of the best f/1.4 lenses can match their f/2 counterparts stopped down. This is very rare, however. There will always be left over aberrations in the extreme corners of the faster lens.

I cut of the auto-aperture pin to put on EOS adapter so can even use as AF with Techart LM-EA7/9 on Sony FE. Interestingly my copy has 1/3 clicks stops from 1.8 to 2.8, 1/3 stop clicks from 2.8 on, so closing aperture just 1-2 clicks improves sharpness nicely without showing yet the ugly 6 blade aperture...

      @@KNURKonesur The Minolta is quite unique compared to other lenses. It's a 6 element f/1.4 where every other f/1.4 50ish lens I have used are a 7 element. It has a very large image circle, but it has strong curvature which becomes more apparent when used on the GFX and the corners are revealed. I also compared the bokeh of the Minolta 58 f/1.4 to any other lens I have in that range, and it is the smoothest. I am not sure I agree about the less SA because I imagine the smoother bokeh is because of under corrected SA because it's only a 6 element design especially SA wide open at f/1.4. My Topcor 58 f/1.8 will achieve corner to corner sharpness for landscapes especially at f/8-f/11 on the GFX. Corners become very nice by f/4 but aren't perfect yet. More soft vignetting at f/4 than f/8, however.

    the feel of the lens in your hand is not something you can ignore, the more you use different lenses. some lenes just makes you want to go out and take more pics, just by the way they feel in your hands. the Voigtländer 58 1.4 that was mentioned in this vid is one. i use it on a fuji xm1 with a m mount adapter, and it is a joy to use.

      It is a big issue to me, especially adapting full frame lenses to GFX, where the camera is quite big and then adapter + lenses usually having the focusing ring at the front mean ergonomically it's not a pleasant "feel". So after a long search for the one lens I want to keep, I disassembled it, took out the optical block and rehoused it into a helicoid which is much wider and easy to operate without "hunting" around the tube of the lens. So as much as I agree it's an important thing you can't ignore - there are ways around it with enough determination ;)

      Kind of wishing I'd realized sooner that 44m is not the same thing as the 44. But the 13 bladed 44 is more expensive.
      I'm sure this one will still be worth the money for me to explore with, and if I really crave the slightly swirlier bokeh I could more easily get a 44-2 in the future.

      @@Simonsutak At your previous radioactive video, you mentioned you owned 998134 and 1378881 8 element. I am curious any difference between them in the color rendering. Will the 1378881 seem to be slightly more yellow in color? Besides, is it make sense that I buy one more earlier version which is 9xxxx? I have already owned 138xxx 8 element.

      @@ochk846 Yes, I still have those two lenses. I've just placed both lenses up against a white sheet of paper, and to my eyes, the earlier lens's glass has a slightly warmer tint. But it's only very slightly warmer. Could easily a result of how this specific lens was stored over the decades and how the coatings reacted.
      Personally, I really don't need both lenses from an optical point of view. I only bought the 137**** as well because I found it in a thrift shop. I'd only buy a 9****** versus a 1****** if I found one for a "cheap" price (i.e. below what the 1****** go for on ebay). They are rarer, and probably better investments, if the price is right.

    Sorry that you paid something for a bad rubber 58 1.8, and that you ended on a version of the 58 1.4 you find a bit desapointing.
    You should sale these two things and have nicer versions of these lens. Vintage lens hobby is a hard one, you can't allways be lucky.
    Btw I would be cautious with some 9900 version of the 58 1.8. With less than good color accuraty.
    The 11626 seems to have an out the world color accuraty, has your video show us. So this is what we know. And I don't know why something chnaged between the two series.

      It's also a big gamble if you get into adapting and rehousing cinema projection lenses for medium format cameras, technically all have similar designs (either Petzval or Double Gauss) but every brand and every series has very different rendering and it's really hard to find any samples or info about some brands.

    When compared to the Ultron look how much more contrast and 3D impression the Topcor produces wide open.

      I don't know, I'm afraid, as I don't test the lenses for astrophotography. I recommend you search PentaxForums - there are some excellent photographers on that forum who do plenty of astrophotography.

    Why does the electronic shutter have an effect on the bokeh?

    • @KNURKonesur
      @KNURKonesur 8 днів тому +1

      Electronic shutter doesn't cause the problem, it's the electronic front curtain shutter setting which is supposed to reduce shutter shake, but at fast shutter speeds messes up the picture backgrounds and affects bokeh

    Do you have any preferences in terms of video? Just curious what your favorite vintage lenses would be for a cinematic set.

    • @Simonsutak
      @Simonsutak  2 дні тому +1

      I don't really use my lenses for cine work, or know cine lenses well enough, to have a meaningful opinion. I'm currently testing a new (and not yet launched) manual focus cine lens, so after that I might better understand what it takes to produce a good cine lens and the differences with conventional vintage/film camera lenses. Personally, I most often use a Sigma 30mm f1.4 for video work. I like the auto focus!
