The VS100-300 extends and rotates the front end when focussing, just as the VS80-200 does.
Zooming moves the front end and extends the lens up to 20cm from mount to tip at 300mm, which really makes it bothersome not having a tripod mount.
Both lenses are great examples of the Carl Zeiss expertise as a lens maker. On my two Sony cameras, the A7 and the A7R III they each render images with the typical Zeiss fingerprint: great contrast, micro contrast, saturated and punchy colors, sharpness and smooth bokeh. These are also the qualities that are the recipe for some great 3D impression.
At 200mm both lenses seem equal to me. The differences that I find are more due to imperfect focussing (despite several tries with the best possible effort) than to actual differences in performance. Once one lens is ahead, sometimes the other. Only longitudinal CA are visible more with the VS80-200. Both lenses exhibit some degree of lateral CA, but not at a level that bothers me.
Wide open both Vario-Sonnars perform quite a bit better than the OM Zuiko 4/200 that is overcast with some spherical and some longitudinal chromatic aberrations. At f/8 all lenses perform equally, but the VS has the least amount of lateral CA.
A word of warning:
Since both lenses are rather slow, hitting perfect focus is very difficult, even with a tripod and when trying your best with maximum magnification and careful focus. I found myself trying to judge sharpness with images being focussed just a little differently (without noticing at first). So if you think your lens is no good, be sure to first shoot another couple of sets before your final judgement.
The VS80-200 has a stronger vignette that extends quite far from the edge of the frame towards the center. The vignetting is even and smooth, which could be nice for concentrating the view on the center of the frame. The VS100-300 vignettes quite a bit too, but extends less towards the middle of the frame. It has particularly dark corners which bothers me more than the stronger vignetting of the VS80-200, especially in a landscape scenario with high contrast, like the ones with the cement plant. On the other hand it can be corrected quite easily in post production.
I took sample shots today at 100mm and 200mm and will provide the samples below. In my opinion at 100mm (at the distance I chose), there is no distortion to speak of. At 200mm both lenses exhibit a very light pincushion distortion. The VS100-300 still has that pincushion distortion at 300mm. But, see for yourself:
When it comes to using the lenses with strong lightsources in or near the frame, there is a clear difference between the two lenses. While the VS80-200 handles it quite well, keeping up color and contrast at an acceptable level, the VS100-300 overcasts the frame with a veil. Also it flares in various colors, which the VS80-200 does far less. The samples were obviously taken in an extreme scenario, but still you have to be aware that using the VS 100-300 in strong backlight may be a real problem. The VS100-300 does produce nicer (8-pointed) sunstars, though. The sunstars of the VS80-200 have 18 points and not only due to that attribute are less defined.
The "small Airwolf" from VARIO is a 650 size scale helicopter. You can power this remote-controlled model helicopter with electric propulsion. The film helicopter (Bell 222 with lateral fuselage widening) is an invention of Universal Television and Belisarius Productions. The myth of legendary performance potential surrounds him as much as the legends of his film history. Everyone secretly dreams of spectacular flights with an AIRWOLF. There are no limits to your imagination when building this model! The kit contains a large number of dummies and comes into its own with additional rivets (20,000 for the film helicopter). We offer this helicopter in GRP (Ord.No. 2001) or Carbon (Ord.No. 2008).
The Skyfox mechanics is a classic, VARIO original product. Where glow plug nitro engines used to be, today a small, powerful electric motor drives your rotorcraft. Skyfox, that stands for lightness as it is desired in electric flight resulting in longer flight times. The kit with Ord.No. 2001 (or its carbon version Ord.No. 2008) contains the frames for the Skyfox mechanics. The fuselage doesn't provide functional doors, but with a little skill and initiative you can exchange or charge the batteries via an individually created revision opening. You can choose between two Skyfox drive sets: for 6S or 10S LiPos.
The "small UH-1D" from VARIO is a 750 size scale helicopter. You can power this remote-controlled model helicopter with electric propulsion. Bell Helicopter is the creator of the man-carrying version. Following the full size helicopter the model also has an exceptionally long rotor shaft. In comparison to the Bell 205, the 204 version has a shorter cabin.

Around the world there are countless legends about the Bell 204 that make them so popular. Better known as UH-1 Iroquois or, above all, by her nickname Huey, derived from the original designation HU-1. The list of all variants of the Bell 204 / 205 helicopters would be too large to write here. The differences were in the engine, but also in the equipment: eg
With our intuitive, easy to work labeling and engraving software VarioSign you can create the labeling data within seconds, sending them to the plotting or engraving system. The data of all available common elements and tags for the industry, such as for terminal blocks, wires, cables, devices, cable ties, shrink tubing, labels, legend plates etc. are embedded in the software database.
Please download the demo version of the software from our web site under "Downloads" and discover the capabilities of how fast and easy you can work with our intuitive program.
Extensive library of labeling data
In order to create the labeling data for elements and tags such as for terminal blocks, wires, cables, devices, cable ties, shrink tubing, labels, legend plates etc. in various sizes an extensive library for the named manufacturers is embedded, with a frequent update service.
With multiple built in functions, like single, multiple, series and row labeling, the labeling data can be created easily in a comfortable way, other formats can be imported through import filters with a click.
If you like to use material and elements not available in the general database, you can design those as custom elements precise and rapidly. Creating templates for single or multiple tags or for rating plates the software guides you in order to achieve the result most efficiently. The custom designed templates are provided in the user folder ready to be used for plotting or engraving.
The software VarioSign also provides special characters and symbols frequently used in the panels and plants. Additionally, all country specific characters of the west and east European countries are available as well as Cyrillic, Greek, Hebrew, Arabic and Turkey character sets.
Our software VarioSign also holds various fancy letter fonts for engraving e.g. name plates etc. Graphical symbols, used in the industry, are available through the extensive library and are frequently updated. If you require any specific symbol outside the library, please get in contact.
If you are looking for a brand labelled version of the software we offer a specific OEM version, following your design. Additional functions and modifications can be implemented according to your demand.
Draco vario SDI Extender
The Draco vario SDI extender brings SDI and KVM together using an IHSE direct-connect KVM/SDI converter card, which combines and converts between SDI video and digital video signals and eliminates the need for external third-party conversion/extender units. As a result, users can reduce cable clutter, assembly costs, AC power requirements, and system complexity. Furthermore, users are no longer limited to the fixed package sizes of third-party converters because each IHSE SDI converter can be installed in all IHSE vario frames. Users can build specialized assemblies with upgrade cards supporting PCM audio, RS-232, RS-422, or USB 2.0 embedded in parallel with the SDI transport.
Draco vario Remote IP CPU
KVM meets DVI with the Draco vario Remote IP CPU, which combines the functionality of a thin client with a KVM extender (transmitter) for seamless KVM connectivity to an IP infrastructure. It uses RDP, RemoteFX, SSH, and VNC protocols to connect individual workstations to virtual machines as thought they were accessing real PCs, with immediate access and single sign-on for ease of operation. Further remote protocols will be incorporated in the future and can be made available on demand. A single Remote IP CPU can host up to eight simultaneous sessions. This space-saving solution is fully compatible with the Draco vario extender and the Draco enterprise and compact matrix switch series.
