Kamlan 50mm f1.1 Review & Sample Photos

  • September 13, 2018

Kamlan 50mm f1.1 Review & Sample Photos

The KamLan 50mm f1.1 lens is a super fast manual focus lens by Sainsonic for mirrorless cameras. It’s designed as a very inexpensive specialty lens with extremely shallow depth of field with buttery smooth bokeh. This is achieved by a f1.1 aperture with 12 circular aperture blades.

Its simple design with a low element count makes this lens shoot and behave more like a retro lens with extreme characteristics, rather than a modern lenses designed for corner to corner sharpness and aberration control.

For example, the Fujinon 56mm f1.2 has almost twice the element count which corrects for most of the aberrations and corner softness by incorporating a double-sided aspherical lens and two ED lenses. While this is great for overall image quality, micro contrast and color rendering suffer slightly.

However, it’s not always about element count. Even though the Kamlan 50mm f1.1 has less elements, it behaves much worst in most situations due to inferior glass and coatings – More on this later.

The Kamlan 50mm also doesn’t have any aspherical or ED lenses like most modern lenses and because of this, it has issues with chromatic aberrations and corner softness. Unlike a lot of older lenses, it does have much better multi-coatings with good control over basic flaring but still pales in comparison to a modern Fujinon or Zeiss lens.

 

KamLan 50mm f1.1 Lens Stats

Focal Length: 50mm equivalent to 75mm
Aperture Blade: 12 circular aperture blades
Elements: 5 elements in 5 groups
Coatings: High quality multi-coating
Focus: Manual
CPU Contacts: No

Pros: Very shallow depth with great bokeh – Decent contrast (in the right conditions) – Good saturation – Low barrel distortion – Good build quality

Kamlan 50mm f1.1 Review | First Impressions

 

 

The Kamlan 50mm f1.1 is a decent lens for the price. Because of the 12 circular aperture blades, it has buttery smooth bokeh and extremely shallow depth. The lens also manages to keep some nice sharpness even when wide open at f1.1, but mostly only in the center. It’s a little tough to focus when at f1.1, but with portraits and still objects it’s very doable.

The focus has a far throw so getting precision is easy. A full 180 degrees turn will take you from infinity to its closest focus, so you can usually find the focus without needing to take your hand off the focus ring. However, sometimes if you go from close to infinity, you will have to adjust your grip and keep turning that focus ring.

I’ve found skin tones to shift towards pink when shooting people with fair skin. Of course, I usually heavily process and correct my photos so it’s not much of an issue. There is some vignetting and loss of sharpness towards the edges when wide open. Colors render very nice even when wide open (except for the slight pink / purple color shift), but there are a series of issues with chromatic aberrations – see the shot below.

 

 

The fun of this lens is to shoot wide open or close to it. It’s challenging, but the circular 12 blade aperture creates some really nice bokeh and very shallow depth.

 

 

This lens has some decent contrast and color rendering when under somewhat calm lighting. However I’ve been using this lens more regularly and have been getting some very inconsistent results. It would seem the lens really suffers in very bright scenes, like those days when it’s slightly hazy out and light is scattering everywhere. In these situation, contrast and micro-contrast really suffer and images just turn to crap. This could be from poor glass chemistry or inferior internal element coatings that cause light to scatter reducing transmittance and overall fidelity.

You can see what I’m talking about in this first shot compared to the second, and even the second shot still underperforming.

 

ISO 200, f1.1, 1/11000
ISO 200, f1.1, 1/8000

 

Because of this inconsistency and sensitivity to bright scenes, this makes the lens a little difficult to use as a walk around every day lens. The image just falls apart.

Stopping down to f4 or f5.6 yields the best results in terms of contrast, even wide open when carefully used in the right situations, it can be a very fun lens for street, portraits or black and white photography and it ultimately has some decent pop. Nothing like a Fujifilm lens, but you do get a lot for your money with this one.

When it comes to overall performance in terms of straight up sharpness, color and contrast and micro-contrast, I prefer it to the Helios 44-2 or Industar 50-2 in this regard. Or even the new 7Artisans 55mm f1.4, which is fast enough while producing much better results for the same price. Review coming soon.

 

Beautiful color saturation and micro contrast when stopped down slightly.

 

Build Quality

The focus and aperture rings are really nice. They are firm but smooth so you won’t accidentally change focus or aperture and they have a nice grip. The aperture ring is de-click so you get very smooth transitions if changing aperture when shooting video. 

It’s actually a great lens for video because of the size, light weight and build quality.

It has a very nice almost Satin finish. It’s built of what feels like a thin aluminum and doesn’t feel light or cheap like your typical Sony lens, for example the Sony 50mm f1.8 feels like a cheap toy – although I do like that lens too.

The plastic lens hood is very secure and somewhat hard to get on and off. Actually, for my first few days of owning this lens, I thought the hood was permanently attached. Needless to say, it doesn’t rattling and isn’t loose like with a lot of Fujifilm and Rokinon lenses – my biggest pet peeve.

The rear lens cap also stays firmly fixed to the lens, unlike Rokinon and many Fujifilm lenses where you open your camera bag only to find your rear cap has come loose possibly scratching the rear element. 

The lens cap feels a little bulky and cheap, almost like it came out of a consumer 3d printer or something, but it works and fits.

 

 

The Kamlan lens is a nice Fujifilm X-Mount lens, but it’s also a nice Sony APS-C E-Mount lens or Canon M-Mount lens. The quality on either camera system will be the same.

My sample photos here are shot with the Fujifilm X-Pro 2 and the Fujifilm X-T2, but expect to see the same characteristics when shooting with Sony or Canon mirrorless cameras.

You can also get Kamlan 50mm f1.1 as a Micro Four Thirds Lens, but it will give you an equivalent field of view of a 100mm lens because of the Micro 4/3 crop factor. On a M43 camera most of the severe problems with edge and corner sharpness will disappear due to this crop, so it’s actually a really nice option for m43 shooters.

Is this a must have lens? 

Only if you want to mess around with super shallow depth of field. For around $150 this lens will produce some nice characteristics with good build quality, plus shooting at f1.1 is a lot of fun! This lens also has only 5 elements, which should allow it to produce really nice contrast in the right situations.

 

ISO 200, f5.6, 1/1280

 

High quality lenses can get away with more elements to some extent, like Nikon and Fujifilm with their ED glass, but they use these extra-low dispersion lenses with a composition of lanthanum dioxide, zirconium dioxide, calsium flouride or titanium dioxide. Older retro lenses would use radioactive thorium or lead to help light transmittance. This lens seems like it uses lower quality glass, so even though it has less elements than a Fujifilm, it doesn’t really compare when it comes to overall rendering and image fidelity.

 

ISO 200, f5.6, 1/150

 

This lens doesn’t use any advanced elements or composite (that I know of), so you end up with a low element count and with decent contrast and color, but tons of chromatic aberrations.

More glass or low quality glass with poor coatings = less contrast and saturation. That’s why everyone loves the Industar 50-2, or the Jenna Tessar, they are 4 element lens. The advantage some of those retro lenses have is that they are designed for 35mm cameras, so the APS-C crop of Fujifilm cameras cuts out most of the edge and corner flaws. On this lens, you just have to deal with the bad corners. Which is fine right? You’re not framing your models face in the top left corner anyway.

The KamLan new is only $150 bucks and is worth considering for photographers that like having fun with old school style gear with very shallow depth, but really that’s about all your getting.

 

 

Sharpness

 

Sharpness is nice in the center but along the edges and corners it’s pretty pathetic until about f5.6 and f8. The corners never really get sharp. You could maybe focus for the edges but then your center would be sharp. The sweet spot in terms of contrast is around f4-f5.6, after f8 diffraction kicks in and the image overall begins to lose quality, although you will have increased depth of field at higher apertures which can help sharpness in those edges and corners.

I shot these tests about 5 feet from the brick wall.

Micro Contrast

 

Micro contrast is decent with this lens, better than any Sigma at least.

Micro contrast gives the image that pop, it’s also known as perceived sharpness. What micro-contrast will do is give the image a lot of clarity and detail even though you don’t necessarily nail the focus. Images will look sharp and defined while not necessarily being sharp. This is really important for black and white photography and is a really nice characteristic to have on an f1.1 lens where you’ll often see slightly softer details when shooting wide open.

 

 

Good micro-contrast usually goes hand in hand with a lens having good contrast overall, and the KamLan 50mm f1.1 can produce nice contrast if you keep it out of direct bright light, or away from a lot of scattered light.

Vignetting

 

Vignetting isn’t terrible but it’s not great either. It starts at f1.1 and only slightly improves as you close the aperture. There is also a slight color shift along the edges and corners, but you’ll only notice it when shooting solid colors.

You can see it gets slightly more purple / pink in the center and it’s slightly more blue along the edges. This is probably where that pink shift comes from in the skin tones.

Chromatic Aberrations

 

Chromatic Aberrations are not very well controlled on this lens. I’m mostly seeing green CA along areas of high contrast and purple in the corners. Having high CA is usually a trade-off of having a low element count lens. You get chromatic aberrations but you get phenomenal micro-contrast. This is why I say this is a great B&W lens, because you won’t notice the CA as much.

 

You can see some CA along her left cheek when shooting wide apertures.

Bokeh is pretty rich but gets a little busy towards the edges. There is also a very subtle swirl to it with some cat eye effect towards the edges and corners.

Sansonic KamLan 50mm f1.1 Review | Bottom Line

 

The Kamlan 50mm is a very fun lens with decent contrast, beautiful bokeh and very nice color saturation. The lens is a little challenging to manually focus at f1.1, but you do get use to it. I typically stop down to about f2 or f2.8 when shooting street photography because focus will be too difficult on moving object. On still subjects at f1.1, it really isn’t that hard to focus and it creates some very beautiful background separation and bokeh. To get the best image quality when shooting f1.1, stay at least 4-5 feet away from your subject to get past any of the spherical aberrations that come from focusing wide open while close up. This is usually the case for any fast lens.

 

ISO 200, f5.6, 1/420

 

It’s can work for black and white photography and street photography, but ultimately there are better lens for a similar price and I would really reserve this lens for when that super creamy bokeh with extremely shallow depth of field is needed.

Chromatic aberrations are pretty severe, so it’s not an ideal lens for a landscape photographer or wedding photographer that wants a perfect image from corner to corner.

 

Toddler Reflections | Kamlan 50mm f1.1 Sample Photo

 

The Kamlan 50mm is fairly soft and smeary along the edges and corners. While stopping down to about f5.6 fixes a lot of this, the corners still remain pretty smeary.

Despite the negative characteristics of the lenses, I’m still have fun with it.

It’s build quality is also nice for the price and feels really good in the hand. The high contrast and color saturation make up for most of the flaws and it’s a very fun casual lens.

I’ve seen reviewers complain that this lens doesn’t get much brighter when opening up from f2 to f1.1, which should give over a full stop of exposure. From what I understand, once you get in the aperture range of around f1.2, lenses begin to have a diminishing return on how much brighter the exposure gets, plus with a cheap lens like this, you’ll likely experience more aberrations and refractions that will ultimately reduce the light transmittance as you open up.

 

Now – 7Artisans recently released a 55mm f1.4 that I’m reviewing. It might be an all around more practical lens if you don’t mind something a little slower. f1.1 vs f1.4 really isn’t that different. Click the little bell in the bottom right and I’ll send out notifications when that review is ready.

 

About Sainsonic

Sainsonic is a Chinese company that makes all sorts of crap. For whatever reason they’ve decided to start making lenses. Or at least they are and branding and marketing the KamLan lenses. They have a few options out there for Sony E-Mount cameras, but this is their first lens designed for all the different mirrorless cameras. I’m not sure who is actually make their lenses or where the designs come from, but so far they seem pretty nice.
