On Zeiss announces Compact Zoom CZ.2 15-30mm T2.9 lens news story (62 comments in total)

RPJG: Question from a dummy; what is the third-from-the-left set of numbers on the barrel?

Cine lenses have two sets of focusing marks so that they are visible on both sides of the lens - useful for focus pullers

Frank B: I have been using Adobe Photoshop for many years as a standalone. I update each time a new version is issued. I will not be forced to subscribe to software and services I do not need in order to get the latest version of Photoshop. I will use CS6 until competing software comes along that better meets my needs, I will not subscribe to Photoshop CC. I currently also use LRoom 4, but may switch back to Aperture, simply because I do not want to continue to do business with Adobe.

@Stu 5 but what happens if Adobe drops Lightroom? In fact Adobe refuses to confirm what will happen to Lightroom beyond v5.

On Cine System Tripod Dolly and Mount Review article (70 comments in total)

I would never buy this especially @ $450. As mounted on a car (suction cups) nothing unusual however supported load of 5lb is not enough. I would not trust 5lb equipment to this mount.

As a dolly, based on sample video, it really sucks. The movement it produces (again, based on video) does not look good - it's a toy, and there is no smoothness, and it moves like a toy. There may be some uses for this thing, why not, but $450? There are better ways to invest such money into video equipment. Obviously my personal opinion.

Francis Carver: A lens is a lens.... now, the manufacturer like Canon may affix to the model name something fancy and smart-sounding, like "Cinema," but still... a lens is a lens. These would be interesting; although certainly not unusual single focal lenses if sold for around $1,000, well $1,500 maximum, but at the crazy prices alluded to in the press release, i.e. OVER FIVE THOUSAND DOLLARS (!!!), you won't see many camera stores stocking up on them, will you now? Well, maybe in Riyadh and Zurich.

And Francis so that you start learning something about cine lenses other than their names/manufactures, this is called "lens breathing"

Cy Cheze: "... to meet high optical performance levels, including 4K (4096 x 2160) production standards."

Which Canon camera currently shoots 4K video? I suppose $5k for a 4k lens is not much, if one has $15k to buy a 4k display too. Really, high-spec / low volume articles must be priced rather rich to be worth the trouble to make. There is no advantage in price-cutting if the commercial market is very select and the production budgets are all seven figures and up.

(1) EOS 1D C can even "capture 4K (4096 x 2160), 24p (23.976) content directly to its on-board CF memory cards." Call it any way you want.

(2) Comparing Canon's 4K cameras to what other manufactures offer in this area is a different story. Switching topic? Have nothing more to add?

acidic: What does "T" mean? As in T3.1 and T2.2. Is this Cine-speak for "F"?

Wrong again. T-stops are f-stops adjusted for light transmission efficiency. F-stop is mostly a mathematical concept. T-stop is what happens in real life. The latter always was and still is extremely important in cinematography.

The reason is in consistency in output needed since (1)film consists of many "pieces" and (2) the nature of filmmaking where pieces/clips originate from different cameras, locations, light conditions, often shot by people who may not even know each other. Efficiecy of modern lenses not enough to use Fs

Because of this, cine lens designers try to facilitate production and post-production. It relates to both, optical and mechanical aspects. Example:you may have noticed the diameter (and not only) of new lenses is the same and consistent with previously released lenses by Canon. Otherwise, it would be a nightmare to change lenses connected to matte box, follow focus, etc. It is very difficult to design lenses following such strict requirements. Costs go up.

Roberto Mettifogo: very good for movie making, solid, precise focusing and follow focus ready, precise markings on the barrel, don't complain about price guys, this is not for the sunday photographers... it is a high end lens for digital cinematography, and most of the user will rent them, the price is good.

AF works well with photo. With video it does not work this way. There are situations when AF is needed, for example in ENG when you deal with events and cinematigraphic qualities of your footage are not a major concern.

Usually, in filmmaking, you never use AF because of the moving nature of everything you deal with. Only humans are capable of deciding what and how should be in focus. Focus pulling is usually performed by an assistant. Scenes are staged so that focus is set exactly how it's needed.

All sorts of aids are used. And yes, tape is still used with digital cameras as well as all sorts of markings including precise and calibrated markings on lenses and often, in addition, manual markings on follow focus rings so that when the actual scene is shot, you already know how to pull the focus. Even marks on the ground. Canon cine lenses are very high quality - watch this http://vimeo.com/56357604 to see how some of them compare with L lens - you may be surprised.

@FrancisCarver At this very moment Canon has two 4k cameras c500 and 1D C. Both are in stock in several stores right now including B&H. Your arrogance does not know any limits.

I think actually DPReview can consult others how to design web sites.
