ZOOM IN HELICON REMOTE SOFTWARE

its very beneficial when shooting Macro Photography, as your lens won’t extend and creep up and bump into the subject.

Its cheaper to manufacture, bringing lens prices down.

The advantages on an Internal Focus Lens are that: However, as this lens’ front barrel doesn’t extend like the 50mm lenses do, in order to add more space to the lens when this happens, something else has to give way, in order to make way for the shift in the lens group, which in this case is the Focal Length (zoom) lens groups.Īs I focus to Infinity, the Focal Distance lens group moves into the Focal Length’s space, forcing them to also move, in order to not collide with the Focal Distance lens group, causing a side effect, which is a slight change in Angle of View and Magnification (Zooming/Focal Length), when changing Focal Distance (changing focus point).Īs mentioned earlier, the Internal Focus lens system does come with other great benefits though, which outweigh the Focus Breathing issue, and are the reasons why External Focus lenses aren’t manufactured anymore: This means that they have to move somewhere, inside the lens.

The Internal Focus Group lenses of the 70-200mm, are still moving inside, as they have to, according to the physics of light.

Our Nikon AF-S NIKKOR 70-200mm f/4G ED VR ($1,396.95) Zoom lens, is unfortunately not so lucky as it also has Focal Length Glass elements inside to factor in. Prime lenses light he above mentioend, can easily get away with moving their barrel back and foirth, as they don t have any zoom lenses onboard to worry about. Helicon is a dedicated Focus Stacking software, so its no surprise that it did a better job than Photoshop here, but the fact remains that Focus Breathing can become an issue in these scenarios. However, the far more sophisticated Helicon powered through the images and was able to overcome the Focus Breathing.

This can result in your software having a very difficult time merging all images into a single stack successfully, due to this misalignment.īelow are the results of Focus Stacking 12 images of a plant in both Photoshop and Helicon, shot using a Nikon AF-S DX Macro 40mm f/2.8 G ($276.95) lens, shot on a Manfrotto 190XPRO Tripod with Ball Head ($283.17).Īs you can see, Photoshop had a very difficult time with this and simply couldn’t figure out the stack, due to the Focus Breathing that exists. In this case, when doing your images Focus Stacking on your PC, you will notice visible changes in angle of view, compared to the Closest and Furthest Focal Distances distances (especially at infinity). The second situation where you can easily identify Focus Breathing issues, involves the art of Focus Stacking when shooting Macro, Product, Landscape or Architecture photos.
