Voigtlander 50mm f/1.5 lens test sample shots

It's one of those lenses that you have to get to know to really appreciate. I've had it for a couple of weeks now and my opinion changed a complete 180. And that just proves that doing tests of studio setups and preparing resolution charts sometimes says completely nothing about a piece of equipment. This lens has integrity and there are no numbers that can express that. Thanks to infoto.pl for letting me test this lens.

Voigtlander as a brand has been known to combine new technologies with tons of legacy and I would say that this lens is a great example of that approach. First of all it is really compact and light and has got a fantastic feel. It just is a small piece of craftsmanship. I know that those things don't affect the way it takes photos, but they do affect the smoothness of focus and aperture rings which is just amazing. The lens feels really solid and there is exactly zero backlash so if at any point you feel like changing the direction of focusing you just do it without the unpleasant rattling. Another thing is that the focus throw is rather short which I adore so you will be able to run through the whole focus range without having to let the focus ring go at any time. (some people might not like this, but it wasn't a problem for me)

The next thing that I really appreciate is the bokeh. Not only is it amazing, but it is in perfect sync with my preferences when it comes to stopping down. Most lenses will have the best bokeh at maximum aperture, but to my amazement this one has the best bokeh just a little stepped down. This will probably be caused by the aperture having as many as 10 blades. (Nikkor 50/1.4D has 7 blades for example) Many photographers I know will usually step down half a stop or a whole when they use very fast lenses just to get that sharpness kick in. When I did this with the Voigtlander 50/1.5 I realised that the bokeh at f/2 is even better than at f/1.5. That's why 95% of the photos were taken at f/2.

All the sample photos taken with my Sony NEX5N through a Voigtlander NEX-VM adapter.
What I love: great bokeh combined with superb sharpness (100% crop below) at f/2

butterflies' 'horns' and the fabric of the dress are sharp as a tack at f/2


Another thing that most of those modern lenses lack is the ability to preserve crispness of colour. No trouble with that here:

colour and contrast rendering abilities are just top notch

exceptionally good bokeh visible through the window and pleasantly soft out-of-focus legs


super lens for portraits (100% crop below)

really nothing much left to wish for when the details are as fine as the 'grain'






No lens is perfect and this one isn't either. At f/1.5 the centre of the image is very decent, but like with the lenses from the olden days the corners in this one are just a tad soft. Thankfully stopping it down does a lot of good to the focus as well as the bokeh so no harm there. Another weak point is the hromatic aberration, but this is an issue that all fast lens freaks have to deal with in their own fashion. ACR comes to the rescue so you can remove those green and purple ghosts as easily as it gets.

some chromatic aberration in contrastive sections, nothing serious though

 +

- outstanding bokeh (10 aperture blades)
- solid, well designed and compact body
- sharp enough at f/2
- good colour and contrast rendering
- comfortable focusing / high precision focus ring
- vintage feel

Voigtlander 17.5mm f/0.95 lens test sample shots

The Voigtlander 17.5mm f/0.95 brags spectacular specs and I was wondering if it's all that great. I've recently had a chance to test one of the fastest lenses available in the market thanks to good guys at infoto.pl who made this test possible, so I borrowed my friends Olympus OMD-EM10 (great camera btw) and began the tests.

First of all this lens mounted on EM10 looks just great. The retro elegance is amazing and as it turns out it fitted my palm just right even though the camera is rather petite.

reminds a mint film camera innit?


I needed  just a few seconds to decide that the first results looked great, but I was still rather sceptical until I saw them on a larger screen.

I am quite suspicious of the micro 4/3 system in general as those sensors are considerably smaller. In this case the 2x multiplier comes in handy - it makes the lens a 35mm equivalent for the full frame and fast 35mm lenses are notoriously used for all kinds of photography. Many photographers consider this focal length even more versatile that 50mm. It's good for landscape, portrait and perfect for street photography. But in the DSLR world you don't even come close to f/0.95- you have to make do with f/1.4 and you end up with a really large lens. Twice as big and heavy as this one anyway.

I was booked for 3 portrait shoots on the weekend anyway so I took those babies for a spin and... I took about 15 shots total with my NEX5N + 35/1.4 lens that I adore. I took the other 3000 shots with the Olympus + Voigtlander.

The lens is tack sharp already at f/1.4-2, and still very decent at f/0.95 which I found almost unbelievable.
at 0.95 the image is perfectly acceptable
at f/0.95

at f/4

Sharpness almost all the way through apertures shown on 100% 1:1 pixel crops. The range between f/2.8-f/4 is the sharpest, f/1.4 is the sweet spot IMO
How do the portraits look? Take a peek yourselves:

Shallow (yet very sharp) depth of field is just amazing. I used it at f/0.95 almost all the time, occassionally stepping down to f/1.4 for some shots.
Colour reproduction is great too. Skin tones and the green of the plants look amazing straight from the camera so I only gave it a bit of postprocessing to get this result.




The lens focuses so close you can easily use it for some softcore macro without using any additional macro lenses etc.

With such a fast lens the only annoying thing are those chromatic abberrations as you might have guessed, but I have seen some f/1.4 lenses that had more ACs than this one at f/0.95. Luckily they are easy to get rid of with ACR or Lightroom so I didn't worry about them at all.

Samyang 12mm f/2.0 SAMPLE PHOTOS from Sony NEX5N

Samyang 12mm SAMPLE PHOTOS finally!

I was lucky enough to test the brand new Samyang 12mm f/2.0 wide angle lens for Sony NEX. This lens is so compact!



I've got some samples for you (taken with a 16mpix NEX5N):


The lens has a remarkable resolution. It is sharp at f/2.0, at f/8 it is razor sharp. It would be a good idea to test this lens on a camera that has more than 16Mpix resolution (my camera).
It is sharper than my Tokina 12-24 I have been which is a pretty damn sharp lens. Like the Tokina (or even more than the Tokina) it has considerable colour aberration around the edges - however I didn't have any trouble correcting it with a few clicks in the ACR.







Some full 16mpix resolution samples (aberration corrected):

f/2
 f/4
 f/5.6
 f/8
 f/2
 f/4
 f/5.6
 f/8.0
Sample with an uncorrected aberration issue in the trees:
Unfortunately most ultra wide angle lenses have this issue. Luckily it is easy to fix nowadays so no problem there!

56: The Cheapest TILT LENS Ever! 65$

It's official now. I'm a terrible blogger, but I will try to make up for the silent months.

Over six months ago I bought Sony NEX and surprisingly it proved to be the best camera I have. I have recently purchased a 40$ tilt adapter for M42 lenses and a great M42 lens Cosinon 1.8/50 for 25$. This combo is really great and it allows me to make a whole lot of great photos each day. Just take a look at these snapshots and bear in mind that this great tilt lens cost me 65$!!! CHEAPEST TILT LENS EVER. Long live Sony NEX. (and other mirrorless, apart from the ones with tiny sensors)

Typical tilt miniaturization effect.

This lens has amazing bokeh and very little chromatic abberrations - both great for tilt use.
No particular purpose, just looks cool this way :)
The out of focus areas definitely add ambiance and build atmosphere.
This way you can pick out a subject and separate it from the background.
I was able to focus both on the background and the window I was looking through.
