Initial impressions of the Light Lens Lab 75mm f/2 "SPII" lens:


The Light Lens Lab 75mm f/2 SP II is one of those lenses the company has been teasing for quite a while and one that many photographers have been eagerly waiting for. It took some time, but it's finally here. For this review, I'll be looking at the Silver Chrome version, although the lens is also available in a Black Paint finish.

Just like the Light Lens Lab 50mm f/2 SP II, the new 75mm is not designed around chasing maximum sharpness through modern aberration correction. Instead, it draws inspiration from the classic 1940s Cooke Speed Panchro Series II cinema lenses, known for their softer f/2 rendering, distinctive flare, rounded bokeh, subtle outlining, and more organic overall look.

These characteristics helped give many classic Hollywood films their unique cinematic character, a look that many photographers and cinematographers still appreciate today, especially when compared to the highly corrected and technically perfect rendering of many modern lenses.

Like the 50mm f/2 SP II, the new 75mm is part of Light Lens Lab's growing SP II lineup and is based on a classic Double Gauss optical design. This time, however, Light Lens Lab made several thoughtful changes that improve usability without sacrificing the lens's vintage-inspired appearance. Because a 75mm lens is physically larger and can feel less balanced than a 50mm, they chose to use an aluminum barrel instead of brass. The result is a lens that is actually lighter than the smaller 50mm f/2 SP II, making it more convenient to carry and shoot with for extended periods.

The same attention to detail extends to the hood. Rather than using a heavier brass hood, Light Lens Lab matched the aluminum construction of the lens, creating a much lighter and more practical combination. Best of all, they managed to retain the beautiful classic aesthetic. Looking at the lens, you would never guess it isn’t made from brass.

What makes this short telephoto release especially interesting is the balance it appears to strike between old world rendering and modern refinement. According to Light Lens Lab, the optical formula has been updated for modern digital sensors and even expanded to cover formats up to 44×33mm medium format sensors. Achromatic elements have also been integrated to help maintain balanced contrast and better control aberrations while still preserving the tonal transitions and cinematic atmosphere the lens is designed around.

We will test this in detail, but based on descriptions and initial sample images, the 75mm SP II appears to deliver a similar look to the 50mm f/2 SP II wide open, with softer contrast and an unmistakably painterly rendering. Stopped down, the lens reportedly tightens up considerably with increased clarity and resolution while still maintaining its signature character. That combination is something I always find far more interesting than lenses that look technically perfect at every aperture but lack personality.

I'm especially excited to compare this lens directly against the Light Lens Lab 50mm f/2 SP II because I suspect they will share a very similar design philosophy and rendering DNA. I expect both lenses to deliver similar rendering and overall character, although they may differ somewhat in flare behavior. At the same time, the longer 75mm focal length should naturally introduce a different feel, with stronger subject separation and a more immersive draw than the 50mm version. It will be interesting to see just how closely the two lenses match in color, contrast, flare behavior, and overall rendering style. I will also test it against other 75mm lenses like the MS Optics 73mm f/1.5 Sonnetar for comparison.

One thing I already appreciate about the SP-II series is that these lenses are not trying to imitate the original Cooke lenses mechanically or cosmetically. Instead, Light Lens Lab seems focused on replicating the original drawing signature, which is something many modern lenses have moved away from. The fact that all optical and mechanical components are designed, manufactured, and hand assembled entirely in-house makes the project even more impressive.

To further pay homage to the original cinema lens, the 75mm f/2 SP II features a unique focusing tab design that differs from the traditional Leica style tab. Instead of the familiar rounded paddle shape, it uses a small sculpted fin-like tab inspired by the controls found on vintage cinema lenses. It feels a little unusual at first, but after a short adjustment period it becomes surprisingly intuitive to use. Combined with the generous 200 degree focus throw, the design allows for very precise focusing while still remaining comfortable for everyday shooting.

Physically, the 75mm f/2 SP II is a bit long for an M body, but the lightweight aluminum alloy construction keeps the weight down to only 310g, allowing it to balance very nicely on Leica M cameras. At 73mm long and 54mm in diameter, it remains compact enough for a telephoto lens and pairs comfortably with cameras like the Leica M-D and Leica M10-R without becoming front heavy. The A46 clip-on Reid-style hood is a very nice touch and fits perfectly with the vintage inspired philosophy of the lens.

This is definitely one of the more interesting 75mm M-mount releases I have seen recently because it prioritizes rendering character over maximum correction, resolution, and contrast. If the 75mm SP II delivers the same magic many photographers are already experiencing with the LLL 50mm f/2 SP II, but with the added immersion, subject separation, and perspective of a classic 75mm focal length, it could turn out to be a very special lens indeed.

What's also exciting is that Light Lens Lab doesn't appear to be slowing down. While I can't say much at this point, there are a few interesting projects quietly taking shape behind the scenes. If they continue exploring lenses with this philosophy and attention to character, M-mount shooters may have a lot to look forward to in the coming months.

Samples 1: Late afternoon, first time with the lens

Most of the images were shot wide open at f/2 in late afternoon light, with varying subject distances.

Post-processing was kept minimal, with only light sharpening and small exposure adjustments applied. I used the Adobe Color or Monochrome profile to better highlight the lens's natural color and tonal rendering.

The rendering is smooth, but still has a distinct character with noticeable veiling flare, especially when shooting into the light. I didn't use the hood, though it likely would have helped control it. No corrections were made for distortion, vignetting, or chromatic aberration.

Infinity Resolution and Contrast compared to MS Optics 73mm f/1.5 Sonnetar (M10-R)

I'm always a bit reluctant to do resolution and contrast tests with lenses that were clearly not designed to excel in those areas. Still, it can be useful when comparing two lenses that both embrace character and imperfections. For that reason, my first comparison is with the beloved MS Optics 73mm f/1.5 Sonnetar.

The Sonnetar offers a slightly wider angle of view and is about a stop faster, but I wanted to see how the new Light Lens Lab 75mm f/2 SP II compares when both lenses are set to f/2. I've been shooting the Sonnetar for many years and know it is very soft wide open, while stopping down just one stop to f/2 significantly reduces its spherical aberration and improves performance. It is never entirely fair to compare a lens that's stopped down against one that's being tested wide open, but it still gives us a very good idea of how they compare in terms of resolution and contrast.

What I found is that the MS Optics 73mm f/1.5 Sonnetar very slightly outperforms the Light Lens Lab at the very center of the frame at f/2, which isn't surprising given that it is being stopped down from f/1.5. However, even in the center, once both lenses are stopped down further, the Light Lens Lab and Sonnetar become very similar in performance.

Away from the center, the story changes. The Light Lens Lab, even wide open, performs noticeably better than the Sonnetar, which only begins to approach its performance at smaller apertures such as f/5.6 and f/8. The same trend continues into the corners, where the Sonnetar remains behind the Light Lens Lab 75mm f/2 SP II and never quite catches up, even when stopped down. One thing that stood out during testing was the dramatic improvement in corner contrast from the Light Lens Lab starting at f/4. By that aperture, the corners take on a much more detailed and high contrast appearance, a trend that continues through f/5.6 where the lens reaches its optimal performance.

What stands out most is how evenly the Light Lens Lab SP II performs across the frame, even wide open. This is very similar to what I observed with the previously released Light Lens Lab 50mm f/2 SP II. In fact, one of the defining characteristics of this optical design appears to be its remarkably consistent resolution and contrast from center to corner.


















  1. Distance: Infinity
  2. Focus: Center - Best of three shots at maximum magnification
  3. White Balance: Daylight
  4. Both lenses are perfectly centered, as verified with my decentering test.
  5. Software used: Lightroom with FM Default Landscape Sharpening; all other settings are at default.

    PS: Vignetting, Chromatic Aberration (CA), and distortion were not corrected either in post-processing or in-camera.

Field Curvature

The Light Lens Lab 75mm f/2 SP II shows a fairly neutral field curvature profile at longer focusing distances, which is evident in the infinity resolution tests where performance remains consistent across the frame. Telephoto lenses often display noticeable outward field curvature, and while this lens does show some outward curvature at close and mid distances, the effect is relatively mild.

As shown in the animation below, the focus field bends outward at closer distances. In real world images, this can translate into out-of-focus background areas near the edges of the frame appearing slightly more in focus than they would with a perfectly flat field. However, the effect is subtle and was not particularly noticeable in my real world testing.

As the focus distance increases toward infinity, the field gradually flattens, resulting in a more uniform focus plane and more consistent performance across the image field.

The GIF animation below illustrates how the focus field transitions from close focus to infinity in multiple steps.

The flares are indeed beautifuler compared to the 50mm SPII, if it’s due to the new coatings, I would reiterate that I wish LLL would update the 50mm version with those and why not in the rigid housing, they did it before, I mean not the variant that I want, but a variant and it was coating wise too even though not the ones I want now.
It could be all the more fitting since I think the optical block being less recessed in the Rigid body could make the flaring easier.

Distortion

Most 75mm lenses tend to show noticeable pincushion distortion depending on their optical design, but that's not the case with the Light Lens Lab 75mm f/2 SPII. Straight out of camera, distortion is so low that I wouldn't bother correcting it in post.

In Lightroom, a simple "-1" pincushion correction is enough to remove the very slight remaining distortion. This well-controlled optical design is definitely one of its standout strengths.

Sunstar rendering

For those who care about well defined sunstars, the Light Lens Lab 75mm f/2 SP II produces a very interesting rendering. The 12 blade aperture mechanism uses concave, petal shaped blades, producing a circular but distinctly scalloped aperture shape when stopped down. This differs from most Zeiss and Cosina M-mount designs that use straight blades, which are generally more effective for clean sunstar definition.

This behavior made me curious how the sunstars would perform at smaller apertures.

The lens also shows noticeable ghosting and veiling flare when the sunstar source is within the frame, even when partially blocked as shown in the samples below. This also provides a quick look at the lens flare behavior, which some may find aesthetically pleasing, I do.

From f/2.8 to f/8, the sunstar rendering remains soft and diffuse. The rays are present but not well defined, and the overall effect is smooth rather than defined. In practice, sunstars only become well defined starting at f/11, with f/16 being the optimal aperture.

Below is a sequence showing the transition from f/2.8 to f/22 in full stop increments. With 12 aperture blades, the lens produces 12 pointed sunstars with good symmetry.

Also included in this series is uncorrected vignetting across the full aperture range.

That f/11 sunstar is perfection, IMO.

Could be interesting to see the 75 SPII up against the Voigtlander 75 1.5 at f/2 if you still have a copy.

Are you seeing the same glow from the 75 as we do from the 50 at mid to long distances? It looks a little less prominent so far.

Minimal Focus Distance: Resolution and Contrast

The Light Lens Lab 75mm f/2 SP II focuses down to 0.7m, making full use of the rangefinder system's minimum focusing distance.

As a recreation of a classic optical design, the lens does not incorporate modern floating elements. Its optical formula was primarily optimized for infinity focus, so close-range performance is not corrected to the same degree. As focus distance decreases, spherical aberration becomes increasingly apparent, particularly within 1m and near the 0.7m minimum focusing distance.

To evaluate close-focus performance, I tested the lens at 0.7m from f/2 through f/4. The most significant improvement occurs between f/2 and f/4, where both resolution and microcontrast show a noticeable increase. Beyond f/4, the gains become much smaller, making f/4 the practical sweet spot for close-focus work and, in my opinion, for most shooting distances as well.

The good news for rangefinder users is that I found no meaningful focus shift. This was verified using a ruler test and by comparing images captured at f/4 after focusing wide open at f/2. The results remained consistent, with no noticeable degradation in image quality or change in the plane of focus.

The image sequence below illustrates performance from f/2 to f/4. Focus was set at f/2, and the lens was then stopped down to f/2.8 and f/4 without refocusing, demonstrating minimal to no focus shift. I also include a comparison between images focused at f/2 and stopped down to f/4, versus images focused directly at the shooting aperture of f/4.
