FAQ

I want to use extension tubes with the Trioplan. Do you have any tips?

We recommend buying a set with different tubes, so that you can gradually get used to using them and get to know the various effects of the different magnifications. At high magnifications, we strongly recommend using a tripod! Using an extension tube with the Trioplan increases the soap bubble effect. The extension tubes only use the central area of the illuminated image circle, enabling you to use the highly optimized central areas of the Trioplan and achieve an extremely high degree of sharpness right up to the edges of the image, huge soap bubbles and extremely smooth transitions in the background.

Generally speaking, longer focal lengths are better suited to this than wide-angle lenses.

Which cameras can I use with the Somnium?
Meyer-Optik-Meyer-Optik-Görlitz lenses are compatible with various bayonet mounts, including:

  • EOS bayonet mounts: all Canon EOS models, both analog and digital
  • F bayonet mounts: all Nikon F and D models, both analog and digital. Meyer-Optik-Görlitz also offers a range of adapters to enable you to use your Nikon lens with different cameras.
  • M42 bayonet mounts: all cameras with M42 lens mounts (currently only the Somnium).

​ ​ ​ What lenses can I use with full-frame cameras?

The following lenses from our range are suitable for full-frame DSLRs or the full 35mm format: Figmentum 35mm 2.0, Figmentum 85mm 2.0, Somnium 85mm 1.5, Trioplan 100mm 2.8, Trimagon 95mm 2.6, Nocturnus 50mm 0.95. There is, however, a difference between mirrorless and single-lens reflex cameras. For example, all our of Nocturnus lenses are suitable for mirrorless digital cameras only. ​ ​

What is the crop factor?

The crop factor is just another term for the size of a camera’s sensor. This is always based on full-frame cameras. A full-frame 24x36mm DSLR camera is the standard, with a crop factor of 1.0. The diagonal of the sensor of a DSLR with an APS-C-size sensor is around 25% smaller, reducing the crop factor to 1.5. A 50% smaller sensor diagonal (with the sensor surface only 1/4 of the full-format 24x36mm) results in a crop factor of 2.0. This means that, if you are using a 50mm lens, you need a 50mm focal length on a DSLR with a crop factor of 1.0 to achieve a photo with the full 50mm image. If you use the same lens with a crop factor of 1.5 or 2.0, the DSLR uses only the inner area of the frame created by the lens, giving the impression of a 75mm or 100m lens. The light intensity remains the same, maintaining the light output. ​

I have several cameras. Which products can be used on different cameras via an adapter?

The possibilities are virtually endless. If you want to use your lens for different full-frame SLRs, we would recommend an M42 or a Nikon F bayonet mount, as a Canon EOS bayonet mount can’t be used on a Nikon F camera. Also, please note that you can adapt lenses for cameras with a mirror box (traditional SLR cameras) to use on mirrorless cameras, but not vice versa. ​ ​

How can I achieve the soap bubble effect with the Trioplan?

Much like with the Somnium, there are some basic rules to get the maximum soap bubble effect. You will need as much backlighting as possible from a longer distance. Focussing on a flower around three meters away, for example, will result in uneven backlighting, perhaps due to the tree tops in the background; we recommend focussing from more than ten meters away to get perfect bubbles. The stronger the contrast in the background, the clearer the bubbles. Indoors, you can emulate this to great effect with fairy lights or sequinned or glittery fabrics. ​ ​

What lenses are suitable for filming?

Our lenses with a grid-free aperture setting are the best for this: the Nocturnus range, the Trioplan 100mm, the Trimagon and the Somnium. The huge light intensity provided by Nocturnus lenses is great for filmmakers, as it is not as easy to extract noise from moving images as a photo, where you can select higher ISO values. ​
