PS: The only 85mm f/1.4 I have is the Samyang, which is stunning for a sub-$300 new lens with really good sharpness wide open (but less improvement when stopped down) and nice, soft, bokeh. A lot of fast lenses have their OOF PSF get badly clipped off axis, creating bad-looking sharp edges in the bokeh. then again, even modern portrait lenses often deliberately undercorrect SA a little to smooth bokeh.īTW, the Pentax A looks like is has very little vignetting, which helps the bokeh off axis. However, you'll see that on some newer lenses, where aspherics and more elements (max # elements you can have is higher for better coatings) allowed better SA correction. Some time ago, one could find this old lens listed for sale for about 150, but nowadays popularity drove its market price upwards to around 1000. That was near impossible with fast lens designs using only spherical elements. One such lens is the Meyer-Optik Grlitz Trioplan 100mm f2.8, which became famous due its soap bubble bokeh and unique chromatic aberrations. Incidentally, a perfectly corrected lens has the same, evenly-lit, disc for its OOF PSF both before and after the focus distance. On the other hand, overcorrecting will flip that - which is what you see from those lenses with 'soap bubble' bokeh. Especially for portraits, the closest scene content usually is the subject, so most lenses leave a little SA. SA generally will make the center bright and edges dark behind the subject focus is on, but closer things get the inverted OOF PSF, which has bright edges and a darker center.

That's normal - what you get from leaving spherical aberrations (SA) undercorrected, as was done in most 'fast fifty' and portrait lenses.īasically, the OOF PSF (out-of-focus point spread function) - the 'bokeh ball' - from a lens gets turned inside-out as you pass through the focal plane. But due to their smaller entrance pupil the blur is smaller. The shorter Pentacon AV 80mm f/2.8 shows the same Soap bubble bokeh effect as well - and the short Domiplan 50mm f/2.9 as well.

The focal plane on this lens renders behind the point of focus more blurry than in front of focus, which is unusual. The Meyer Diaplan 100mm f/2.8 and Pentacon AV 100mm f/2.8 could act as Trioplan 100 replacement. Incidentally, tests back then found that the Zeiss T* coating was actually slightly inferior to Pentax. Still, most fast 85s are pretty similar optics. On Kickstarter they are trying to recapture the beauty, art and essence of the soap bubble bokeh with the new Trioplan f2.8/100 lens. Well, the Zeiss 85mm f/1.4 Planar ZK T* has 6 elements in 5 groups, while the Pentax A* 85mm f/1.4 has 7 in 6 groups. I think it's exactly the same as the Zeiss version other than the coatings. Trioplan’s 15 steel aperture blades creates the soap bubble bokeh.My 'best' bokeh lens is probably the Pentax-A* 85mm f1.4. It was based on the Cooke-Triplet, designed by Harold Dennis Taylor in 1893.Ĭonstruction draft of the new Trioplan f2.8/100 The original Trioplan was created by Hugo Meyer in 1916. photography (10)germany (9)lens (7)camera (6)handmade (5)kickstarter (4)nikon (4)koblenz (3)leica (3)stefan immes (3)biotar (2)camera bag.

All you need is nail polish, glitter and a few cheap household objects. If you don’t have 1,500 Euros to spare, you can go for the DIY version. The soap bubble bokeh and use of blur adds a flavor of abstractness to this picture. The most professional, sophisticated but also most expensive way to achieve Soap Bubble Bokeh is with the help of the Trioplan lens, manufactured by Meyer Optik Görlitz. Prototype Meyer Optik Trioplan shows the soap bubble Bokeh the legendary lens is known for. Check out the fully-funded Meyer Optik Trioplan Kickstarter Campaign for your chance to order one of these beauties for your mirrorless camera or DSLR. A soap bubble bokeh monster But is it true let’s find out. Meyer-Optik Grlitz announced today a new Kickstarter to fund the Trioplan f2.9/50, the next lens to restore the brands historic soap bubble bokeh to the.

The soap bubble bokeh of the legendary Meyer Optik Trioplan is coming back preserving the charm of the original Trioplan while updating it for the digital age.
