Adorable 25s - 25mm F0.95 Speed Lens Comparison on Lumix GH3

28 Feb. 2013 - Last week was one of the highlights of my trip through Southeast Asia as I had the chance and pleasure to compare the upcoming SLR Magic HyperPrime CINE 25mm T0.95 to three other highly adorable, wide open 25mm F0.95 lenses. Let us see how they perform on the latest mFT camera, the Lumix GH3!

This little shootout was more a kind of spontaneous incident as we had some daylight remaining at the end of an "Adorable 35s" session planned for that day in Hong Kong with Andrew Chan and some friends. Andrew is the driving force of SLR Magic and very passionate about great lenses - not only those he builds by himself. But let me state that I am not affiliated with SLR Magic and payed for all lenses I got from them. We got some kind support from Bertille Tabourot, who is a stylist and fashion designer from France, living currently in Hong Kong. For this comparison shooting she took the chance to present one of her fancy creations acting as a freelance model.

But now let's talk about the principal performers of this shootout ordered by "age":

  • P. Angenieux Paris 25mm Type M1 f/0.95
    This very compact and beautyful lens was developed in 1953 and at that time the fastest 25mm design. One of the early copies was used by NASA to take the first photographs of the moon from a lunar probe. It is said to have a very cinematic look, a nice bokeh when used wide open and sharp look when stopped down. It is quite hard to find and prices may be around 1500 US$ when in good condition.
  • Schneider-Kreuznach Xenon 25mm F/0.95
    Schneider Xenon designs have their origin already in 1925 when Tronnier derived it as an asymmetrical derivative of the classical double-Gauss design. The Xenon 25mm f/0.95 became available in the 1960s. The particular copy used in this test was manufactured in late 1978 or 1979 and was equipped with a built-in center spot ND filter that could be ordered for special applications. Current versions do not have that filter and look a bit different, see here. Used prices will vary between 800 and 1500 US$ depending on condition and type.
  • Voigtländer Nokton 25mm f/0.95
    This lens was developed by Cosina Voigtlander and became available for the MicroFourThirds mount in 2010. It is known to be already pretty sharp wide open with increased sharpness when stopped down to F1.4 to F2.0. Price is about 1200 US$.
  • SLR Magic HyperPrime CINE 25mm T0.95
    Production version will become likely available in April 2013 and will start at a price of 799 US$. It has cinema lens gears and aperture keeps round even when stopped down. In this comparison we used a pre-production (step 2) sample. For a rating of sharpness and bokeh please see my conclusion at the end of this article.

Overall Picture Comparison (F0.95 / T0.95)

The following pictures were all shot from the same postion between 6:19 and 6:27 p.m. on a cloudy day already after sunset in order to get a nice light mood with some point shaped highlights in the background. To avoid motion blur, exposure times were kept at 1/125s which results in ISO settings already between 400 and 1000 (due to differences in transmission/vignetting and sligthly dimming light) and of course we used a tripod.

Let us start with the Angenieux 25/0.95 at open aperture:


"Maskenzauber" - Venetian Carnival and Maskenball 2013 in Hamburg

Hamburg is not only known as a town with more bridges than Venice, it also celebrates a Venetian carnival since 12 years now. It's an enchanting event for every visitor and a "must see" for every photographer.

This time I decided to catch the magic moments with a SLR Magic HyperPrime CINE 35mm T0.95 mounted to a Sony NEX7 to get that perfect melange of sharpness and bokeh in order to keep that mood of light and poetic noblesse. But pictures speak louder than words...

Conquering The Darkness - SLR Magic HyperPrime CINE 35mm T0.95 Comparison

Right on time for Xmas, the latest masterpiece from SLR Magic - the HyperPrime CINE 35mm T0.95 - arrived here in Germany. If you have seen my article about the first prototype that was presented in September on the "Photokina 2012" exhibition in Cologne, you can imagine my enthusiasm, when the box was delivered by the postman. Here we compare that exceptional piece of glass & metal to a 50mm F1.4 lens on a fullframe camera (Nikon D800E) and to a Voigtlander Nokton 35mm F1.2 ASPH (version I), that was - up to now - the fastest 35mm lens that you could get with Leica M mount.

First let us take a look at the lens and its box. After some discussion about the packaging of its "big brother", the HyperPrime CINE 50mm T0.95 (see my review here), SLR Magic created a high quality box for that lens and wrapped it for shipment into another shock absorbing foam box, that makes already the unboxing a nice experience:


Sony 10-18mm F4 OSS - Eagerly Awaited Wideness

After NEX users had to go for such a long time without a good ultra wide angle, now Sony is on target with its new E 10-18mm F4 OSS (SEL1018). We were very curious to see how it performs especially on the NEX-7, which is very challenging as many short focal lengths adapted from Leica M mount produced strong color shifts.

The zoom lens starts at a viewing angle of 109° comparable to a 15mm UWA lens on a fullframe camera allowing dramatic perspectives for close ups as well as for architecture and landscape photography. The lens is constructed with 10 elements (some with ED glass) in 8 groups, has 7 circular aperture blades, provides a fast autofocus and optical stabilization supporting shooting at low light and video. It weighs only 225g and comes with a seperate lens shade.


Ultrawide Comparison: Carl Zeiss Distagon T* 15 mm f/2.8 vs. Nikon 14-24mm f/2.8 vs. Samyang 14mm f/2.8

Looking for an ultrawide angle lens covering fullformat image circle? We compared the new Carl Zeiss Distagon T* 15 mm f/2.8 with the Samyang 14mm f/2.8 IF ED UMC Aspherical and the Nikon AF-S NIKKOR 14-24 MM F/2.8G ED. With an angle of view of 110° (114° at 14mm), a fast F2.8 aperture and a minimum distance of about 25-28 cm they allow dramatic perspectives for close ups and are suitable for architecture and landscape photography as well.

During this review we will compare resolution/contrast, chromatic aberration, distortion, vignetting and bokeh on typical real world examples as in my opinion this is more meaningful than just comparing technical data and charts. The shots were taken with the "pixel monster" Nikon D800E who's 36 MP sensor currently provides the highest resolution for full frame cameras and with the Sony NEX-7 using an adapter from Novoflex. If you ask yourself "why putting such a lens on the NEX-7 ?", her is my motivation: With it's APS-C sized sensor it provides the same crop factor than the D800 in DX mode or a Nikon D7000 but with 24 mega pixels and so it challenges the lenses regarding resolution even more than the D800E (that provides about 15 MP in DX mode). With it's currently unrivaled EVF and 11.7x magnification it is much easier to precisely adjust the focus to it's optimum compared to the D800E's liveview - especially at bright outdoor light conditions. Last but not least, the NEX system still lacks of sharp and fast super wideangle lenses and adapting ultra wide angles designed for Leica M-mount at the NEX-7 usually produces colorshift on the borders.

Size / weight / build / operation

A first review for the Zeiss Distagon T* 2.8/15 you can find already here so let's just sum up the most important technical data before we go into the image comparison. The different sizes are visible above and the weight you will have to carry (with Nikon F-mount) is about proportional to their sizes: ~550g for the 14mm Samyang, ~730g for the 15mm Zeiss and approx. 1000g for the 14-24mm Nikon. All three candidates are equipped with a chip delivering focal length and aperture information to the camera and allowing aperture control also through the camera. Filters (92mm thread) can only be screwed to the Zeiss. All are of good build quality, the Zeiss provides the best haptic and focus operation and comes with a metal lens hood. The Samyang has the longest focus throw - for my taste too long. You may find the Samyang also in identical construction under different names like Walimex Pro, Rokinon, Vivitar, Bower etc. My sample of the Samyang had a problem with the focus adjustment that is quite often reported by other users as well for that lens: Infinite focus is reached when the focus ring showed about 0.8m on the distance scale. In that aspect my point goes clearly to the Zeiss Distagon.


Carl Zeiss Distagon T* 2,8/15 mm - Ultrawide and Fast!

Looking for an ultra wide angle lens covering fullformat image circle? Than you should take a closer look to the new Carl Zeiss Distagon T* 2.8/15 mm. With an angle of view of 110°, a fast F2.8 aperture and a minimum distance of 25 cm it allows dramatic perspectives for close ups and is suitable for architecture and landscape photography as well.

The manufacturer claims that with 15 elements in 12 groups (including two aspheric lenses and floating elemements design) this lens preserves very natural proportions with minimal distortion, high contrast and exceptional sharpness. So it should harmonize perfectly well even with the latest 36 MP "pixel monsters" like the Nikon D800/D800E. Due to the selection of special glass also chromatic aberrations are nearly invisible and the T* coating is designed to reduce stray light and reflections to a minimum. You can read an in depth review and comparison to two other ultra wide angle lenses here. It is available in two versions, one with Nikon F-mount (ZF.2) and one with Canon EF-mount (ZE). Both versions contain a chip that allows the camera to determine the focal length and control the aperture, the ZF.2 version has an additional option to operate the aperture manually. Focus is operated manually with a butter smooth focus ring with clearly defined start and end point, which is interesting for filmmakers as well.

Due to it's complex construction it is quite big but less bulky than e.g. the Nikon 14-24mm F2.8 wide angle zoom lens. Although it is completely made of glass and metal, it is surprisingly light - it weighs about 730 to 820g depending on the version and fits quite nice e.g. on the Nikon D800E:

Nikon D800E - das Pixelmonster

Nachdem mich bereits die NEX-7 von der Qualität der aktuellen Sony Sensor-Generation überzeugte, legte nun die mutmaßlich ebenfalls mit einem Sony Sensor bestückte Nikon D800/D800E im Vollformat-Bereich nochmals eine Schippe drauf. Sie erreicht mit 36,3 MP und einem Dynamik-Umfang von 14,4 Blenden (gemäß DxOMark Sensor Scores) bereits Leistungsdaten, die bislang Mittelformat-Kameras mit einem vielfach höheren Preissschild vorbehalten waren. Allein das ist schon Grund genug, sich die D800E genauer anzuschauen.

Update: Siehe Ende des Artikels!

Warum die D800E?

Nikon liefert sein neues Pixelmonster in zwei Varianten aus. Die D800E unterscheidet sich von der D800 lediglich dadurch, dass ihr Sensor nicht mit einem Tiefpass-(Anti-Aliasing-)Filter bestückt ist. Der Hersteller weist allerdings daraufhin, dass die damit noch erzielte leichte Erhöhung der Pixelschärfe und Lichtempfindlichkeit, unter gewissen Umständen mit der Bildung von Moiré in feinen Texturen einhergehen kann. In der Praxis berichten die bereits mit dieser Kamera beglückten Nutzer allerdings, dass sie bislang selbst mutwillig diesen Effekt kaum herbeiführen konnten. Sofern Moiré doch einmal auftreten sollte, lässt es sich mit einigen darauf spezialisierten Werkzeugen (z.B. ab Lightroom 4 / Adobe Camera Raw 7) mit relativ geringem Aufwand entfernen, wie z.B. dieser Bericht zeigt. Wer also wirklich das Maximum an feinsten Details auch für sehr große Ausdrucke oder stark beschnittene Crops herausholen möchte, der wird vermutlich bereit sein, den Mehrpreis zu investieren.

Dieser 1:1 Ausschnitt aus dem Titelbild dieses Beitrags zeigt bereits anschaulich, wie hoch die Auflösungsreserven dieser Kamera sind:

(100% Crop aus dem Titelbild, aufgenommen mit dem AF-S Nikkor 50mm 1:1,4 bei F5.6 an der D800E)

Wahl der Objektive

Die nächste Frage, die man sich i.d.R. stellt, nachdem man sich zur Kaufentscheidung durchgerungen hat, ist die Frage nach den "passenden" Objektiven. Eine Kamera mit einem derart anspruchsvollen Sensor stellt die Qualität der verwendeten Linsen auf eine harte Probe. Diese Feststellung machen seit einigen Jahren auch schon die Besitzer von MicroFourThirds- und NEX-Systemkameras, deren aktuelle Sensorgeneration hochgerechnet auf die Fläche eines Vollformat-Sensors bereits mehr als 60 MP auflösen und an denen viele "Altgläser" früherer Analogfilm-Kamerasysteme in mehrfacher Hinsicht nicht mehr den Anforderungen moderner Digital-Sensoren gewachsen sind, wie auch in diesem Beitrag zu sehen ist.

Ob die derzeit angebotenen Zoom-Objektive über den gesamten Zoombereich und bei Offenblende eine genügend hohe Auflösung bieten, wird derzeit von vielen in Frage gestellt. Da ich ohnehin eine Vorliebe für lichtstarke Festbrennweiten hege, entschied ich mich deshalb zu folgendem "Starter-Pack":

V.l.n.r: AF-S Nikkor 24mm 1:1,4 G ED, AF-S Nikkor 85mm 1:1,8 G (2012er Modell) an der D800 E, AF-S Nikkor 50mm 1:1,4 G
