Ecco un hands-on della camera pubblicato oggi, la camera è interessante ma su alcune cose bisogna riflettere..
non è un sostituto di una hsdlr o una mirrorless... è un'altra cosa.. ha poi dei limiti che vanno valutati nel suo range di prezzo (molto aggressivo).
La cosa che mi piace di meno è il peso (1.8Kg), scrive che non è una camera comoda a mano ma da cavalletto..le difficoltà aumentano con la necessità di batteria esterna, sunhud, eventuale viewfinder, rig necessario visto la configurazione... la praticità non sarà il suo forte! Inoltre l'effetto sfocato a cui ci siamo abituati non è facile d raggiungere, servono ottiche molto luminose..
io la vedo bene come B camera su produzioni medie, o come camera principale per bassi budget ma per nulla su riprese tipo reportage, backstage..dove l'ergonomia è molto importante..oltre al peso.. e la praticità..
Insomma il kit completo è corposo:oltre alla camera...lenti, SSD, batteria esterna, ND filter, matte box, rig, view-finder

This morning Craig from Blackmagic popped in to the CVP Midlands showroom in order to let us have a quick †˜play' with a prototype of their Cinema Camera
Since it's one of the most eagerly awaited products of recent years I thought I'd better share my observations with you!
The first thing that everyone at CVP who hadn't previously seen the camera at NAB said was †œI really didn't expect it to be that big!† †“ It seems that most people expect the Cinema Camera to be not much bigger than an iPhone, yet the reality is that it's a fairly chunky unit that weighs in at a hefty 1.8Kg for the body only… At this weight it's far heavier than an SLR and the lack of any natural handgrip position means that in standard form it's really suitable for tripod mount use only. BMD are offering an optional pair of †˜cow horn' style handgrips which will facilitate comfortable handheld use, however with both hands on the grips any kind of on-shot camera adjustments will be impossible without a focus puller and / or a (yet to be invented) BMD Cinema Camera remote control system!
The prototype was fitted with a Canon EF 24-70 f/2.8 zoom lens and the camera's approximately mFT (Micro Four Thirds) sized CMOS sensor delivers a crop factor of just over 2:1 when compared to using the same lens on a 35mm full-frame camera such as a Canon EOS 5D, so to achieve †˜standard' angles of view you'll need short focal length lenses (approx 24mm). At 24mm f/2.8 (or any other setting) the camera's depth of field is not as shallow you can achieve with a larger Super 35mm or full frame sensor equipped camera, so in order to get a shallower depth of field I would want to use either Zeiss' new T/1.5 CP.2 Super Speeds or Canon's f/1.2 prime lenses.
The Cinema Camera's native sensitivity is a healthy ISO400 and at f/2.8 it delivered fully exposed images in our fairly dimly lit studio set. Sensitivity can be increased to ISO800 and 1600 for lower light environments and the increase in noise was minimal. Adjusting the EF lens' iris is easy using the |< and >| buttons, however it is stepped, so for precise or in-shot iris adjustment you'll need a proper manual iris lens.
The camera features both Thunderbolt and HD-SDI terminals, so we connected the camera's HD-SDI output directly to a 42†³ monitor and framed up a few shots in the demo studio. Unfortunately the prototype was far from complete and non-recording so I can't share any captured images with you, but what I can confirm is that the output images were surprisingly good considering the camera doesn't feature any internal gamma curve adjustment or presets †“ Instead it's set up to capture the widest possible dynamic range which can then be colorised in post production using the bundled Da Vinci Resolve software application (or any 3rd party grading software). What this means is that in its native form, in most cases, untreated footage from the camera will look washed out… It's therefore aimed primarily at non-live productions!
The camera is equipped with a peaking function for accurate focusing †“ This is activated by a physical †˜focus' button and it greatly facilitates accurate determination of the focus point, even with the integrated monitor… And on the subject of that monitor I was pleasantly surprised with its image quality and also the clarity and ease of operation of the touch screen menu system. Whilst only a limited number of set up parameters could be changed on the prototype , where adjustments could be made it was a cinch! The brightness & contrast of the display will be adjustable through the menu system, however the prototype was preset to a fairly low brightness level suitable for use indoors †“ I'm hoping that the panel can be set bright enough to allow outdoor use, as otherwise a third party EVF will be essential. Actually, the truth is that if you buy one of these cameras you will need a third party EVF for handheld operation anyway! It's worth noting that the pictured LCD viewfinder sunshade (hood) is included with the camera.
One of the major differences between this camera and every other dedicated camcorder on the market is that more in common with Apple's iPhones, iPads & iMacs the BMD Cinema Camera has a non-removable internal battery. This battery allows only about 1.5 hours of constant operation between recharging, so if you want to use it on location you will definitely need a supplementary battery system for all but the most brief of shoots.
Whilst we're on the subject of the extras you'll need in addition to the camera body itself here's a quick list of the essentials:
Lenses
BMD approved SSD Media
Supplementary battery power supply & cable
Solid ND Filters
Matte Box
Rig & EVF for handheld & shoulder-mount use
Of course the number 1 question we asked is †œWhen do we get our stock† and the absolute truth of the matter is that Blackmagic are un-reassuringly vague on this point, saying merely that †˜some' deliveries will be in July and that they expect further regular deliveries of stock thereafter BUT they expect to be fulfilling customer back-orders until †˜at least' the end of the year… No firm dates or quantities were forthcoming…
So we apologise in advance to those customers who are understandably eager to get their cameras †“ When the Cinema Camera was announced on day one of NAB CVP ordered more than enough units to cover all orders to date and we've ordered more since, so we, and hence our customers are at the front of the queue for delivery †“ However it's clearly going to be a frustrating wait for the vast majority and our best advice is that if you want one of these cameras and haven't ordered it yet then do so without further delay as orders will be fulfilled in order of placement and we realistically don't expect to see it in †˜free stock' until well into 2013!
As another well known manufacturer says to those waiting for their forthcoming products †œExpect delays and you won't be disappointed!†
