In The Wild: Sigma 50-100mm F1.8 DC HSM Art Lens

Sigma's 18-35mm f/1.8 blew people's minds when it burst on the scene a couple years ago. Both the price and performance were unprecedented, as it was (and is) the fastest zoom lens ever created to that point. All the while also being priced at well under $1000. It has no stabilization, but the crystal clear image, along with the wide constant aperture, certainly garnered much respect and attention.

The only problem was, that it's just a bit on the wide end of things. Realistically, to have all your bases covered you would probably need something longer, possibly in the 50-XXXmm range to go along with it, even if you're utilizing both a Speedbooster and dummy adapter on smaller sensor cameras like the Blackmagic Cinema Camera and (Super 16) Pocket Cinema Camera. This two adapter method allows the user to get two different fields of view out of the single lens, which is pretty handy.

Those who saw the lens first hand from CP+ seem to think it's very similar in build quality to the previously released 18-35mm lens, and the image characteristics should dovetail between the two lenses very nicely. The internal focusing and zooming mechanisms will have the video shooter very pleased as well, especially when dealing with rod systems and matte boxes that require cinema style internal mechanics.

Also, I'd imagine this new lens will be "cinevised" with re-housings, lens gears, clickless apertures, etc. almost immediately upon release by people like cinemaglass.com, Duclos, and other lens modification services.

While these lenses not yet officially released yet, it stands to reason that this could possibly be best 1-2 punch combination of lenses for most people, period. Paired with Speedboosters or regular adapters, the focal range available from just these two lenses is pretty unbelievable. Throw in the fact that they are on par (image-wise) with many top of the line prime lenses and it appears to be the makings of an unbeatable combo.

All for under $2000!

The Sigma 50-100mm f/1.8 DC HSM Art lens will be available at the end of April 2016, in Canon EF, Nikon F and Sigma SA mount. It will retail for $1099.

Rokinon/Samyang Announce XEEN 35mm T1.5 & 14mm T3.1 Lenses

xeen_cinema_lenses_set

Samyang/Rokinon just added two new lenses to their XEEN lineup. The XEEN 35mm T1.5 and 14mm T3.1 will now join the existing 24mm T1.5, 50mm T1.5 and 85mm T1.5 lenses in the XEEN cinema lens line up.

The T3.1 on the 14mm is somewhat dissapointing, but also somewhat predictable, as these are based on the same design as the other entry level cinema lenses in the Rokinon Cine DS range. All of these XEEN lenses cover full-frame sensors and come in PL, EF, F, E, and MFT mounts.

While the mismatch in the aperture across all the lenses is a bummer, there are some definitely redeeming qualities about these lenses such as:

  • Better build quality (aluminum vs plastic)
  • Better coatings (less flare)
  • Uniform front diameters @ 114mm (for matte boxes)
  • Uniform focus and aperture rings distance (makes lens swaps and follow focus placement a breeze)
  • Changeable lens mount

These two new lenses in the XEEN line up should be available sometime in March for the same price as the others - $2495 USD.

TUTORIAL: Cine-Mod For Cheap

One of the best things you can do to your DSLR still lenses is to make them more like cinema-style lenses to aid in the aquisition of superb video. While this isn't a true "Cine-mod" its an affordable way for hobbyist and amateurs to get started using lenses that will work with their video gear a lot more effectively.

This generally includes:

  • Lens Gear - Adding a lens gear for follow focus operation

  • Same MM Fronts - Adding all same sized lens front threads in order to be able to swap screw on filters

  • Same Size Lens Caps - Obviously to go with your new same sized lens fronts

  • De-Clicked Aperture - For smooth aperture pulls

  • Mount Convertion - Sometimes you can have you lens mount changed to natively match your cameras mount

Obviously the place to go for this type of lens plastic surgery is Duclos. While it will make your lenses lightyears more usable for video, it will also cost you a pretty penny at about $250 a pop for the basic "Cine-Mod", on top of your already pricey glass.

One way to get almost all the features of the Cinemod for hundreds less is to do it yourself! This includes adding a zip tie lens gear, same sized fronts and lens caps, and in some cases adapting your lenses to a differnt mount.

In this example, I have a Contax Zeiss 50mm f/1.7 (or 1,7 as they say) and I start out my own little modification by purchasing a Fotodiox C/Y to EOS adapter, so that I'm able to mount the lens to my Canon DSLR.

Once you've secured your new mounting adapter to your lens, you'll want some way to use a follow focus with it. Pick up one of these cheap zip tie lens gears from Half Inch Rails. (LINK)

It should look something like this...

Next comes the step up ring, so that you only need to own one size of all your filters as opposed to one for each sized lens. In this case I'm going from 58mm to 77mm but you can find pretty much an adapter for any size.

FInally, matching lens caps. I prefer to buy these much sturdier generic ones from Amazon and eBay since they have a nice spot to put a piece of tape with the lens focal length on it, but you can get original Canon lens caps or whatever you desire. The key here is to protect those lenses!

And there you have it Mount the lens, engage your follow focus, pop on that vari ND, and you are in business!
