am confused!!!!!!!
Nate, why you selling your F350? |
to phil bloom
hi,
can you explain us - if you know of course - something about that new letus if used with ex3 camera. - is this adapter build WITH special (compesating) lens included ? in another words - is this more or less typical letus but with additional lens on the back/video camera side which makes possible using camera without it's own lens on the camera body? thanks, filip kovcin |

Depth of field explained
The above is only the tip of the iceburg. here is my drop of water: DOF is a function of sensor size and f setting. The greater the sensor size the greater the FOV. The smaller the f setting (larger aperture) the less the depth of field (and more expensive the lens). |
Charles,
"Depth of field" actually refers to the depth in a scene in which objects appear in focus. More depth = more of the scene in focus. Because we use expensive accessories on video cameras to simulate the properties of a 35mm film camera, many seem to think that by adding these accessories we are getting "greater depth of field." In fact, using standard photographic terminology, a 35mm adapter gives LESS depth of field. Wider apertures also give less depth of field. Larger formats (film and chip size) give less depth of field at a given FOV and aperture. I think that a misunderstanding of the terminology is what causes so much confusion on this topic. |
Thanks Eric. I was about to take my own life. Good explanation.
|
FOV??? did I write that, Oops, way too long of a day...
Larger or more DOF with A SMALLER aperature, hince a pin hole camera needs no focusing and has an infinite DOF. Larger aperature gives less DOF and an infinitly expensive lens gives a... I don't know what you call an infinitly small DOF, hmm I will sleep on it... Thanks Eric |

Phil, at what time today do you think you'll post up the review on the EX3?
|
I would say midnight tomorrow night GMT
It's all ready...just need to click that publish button!! |
Awesome Phil, cant wait to read about it... Im sure its a fantastic camera, but from the look of the pics of the EX3, its taken a heavy dose of ugly pills... IMO...
:) Cheers |
Could somebody ( other than Philip who's sworn to secrecy) who saw the accidental sneak preview description of the EX-3 tell us what was in it. The article is gone for now.
|
I second Leonard! Whoever have read the article, is there anything way out different from the EX1? From the photos all I can see are the following changes: interchangeable lens / a monitor evf combination with an interesting mechanism / a revamped body with better placed buttons / some additional inputs and outputs / a very useful second accessory shoe placed in an interesting place.
I'm eager to know whether there is the facility to record SD like the 335 and 355's! |
yes, the big secret is that it's the new lens-less organic sensor technology. interesting stuff. could there ever have been a more anticipated moment on here than midnight tomorrow?

You have D1, D2, D3 1/2" Digital, D5 1/2" Component, D6 and so on, but no D4. |
From the little I've managed to dig up I'm guessing the secondary shoe is for a new 60 gig hard drive, redundancy or dumping? Both? Dunno.

I have the whole article including all the pictures, but am not going to post it because I do not want any trouble with Sony.
But this is what I still can find on another website. The PHU-60K is an SxS Professional 60GB HardDisc Recorder. It can be used either by recording directly from an SxS lead to the card slot or transfer from an SxS card when inserted in the other card slot. Announcement of 32 GB SxS cards (2 hours @35Mb/s). Available in september. For the rest you'll have to wait. |
Excellent review Philip! I love your demonstration video where you are showing all the new features. (I was amazed that it is already online - I hope thats not by accident...)
I should have returned my EX1 when I still had the chance to do so, with all the backfocus issues. Sony will have lots of unhappy EX1 owners now... The new EX3 looks like a killer camera! It has everything I miss on the EX1. Thanks Philip for sharing this review. regards, Gerald |

If it turns out the EX3 is better and only $500 more expensive then I'll be a bit frustrated though! |

I have no regrets on buying the EX1 either. The EX3 looks like something to graduate into later on. |

it will be more than that

The EX-1 was to my mind the first really viable pro camera within reach and was ready to take (for me anyway) A huge step and purchase a camera that cost almost the price of a small car. And through Phil Blooms posts discovered the amazing Letus adapter. Making it affordable now to create films. So borrowed over three years £7000
NOW. We have the EX-3 which is even more suited to this purpose than the EX-1. It should have been released the other way round giving people a choice. Many will now sell their EX-1s and buy the EX-3. Very good marketing for Sony whether accidental or not. I think it would be really nice if Sony was to give some kind of trade in deal perhaps on a time limit for those who bought the EX-1 but would rather have purchased the EX-3. It wouldnt be many and would do wonders for customer relations in my opinion. |

Nigels article online again
For those who missed it the first time around: New Sony Solid-State HD Products at NAB 2008 @ dvuser.co.uk.
I suppose the Sony embargo has been lifted ;) So what I like about it so far (and not having seen/handled the real thing) in order of my preference: - Done away with the viewfinder - Better ergonomics (most controls on the left) - Interchangable lens - Frame rate control dial - Flip switch on the LCD - LCD controls are manual dials - Timecode in/out - All bnc's on the back, easy to manage - Mic mount seems sturdier - Cover over te audio levels Also with what I presume to be the same sensor block and standard lens, it will be an exact match to the EX1. Just with some more options. And how about that 2nd cold shoe at the back with the cable clasp on the handle that seems to be purpose build to take the PHU-60K SxS Professional 60GB HardDisc Recorder ;) George/ P.S. Looking forward to Phil Blooms hands on review! |
Does the Letus Ultimate bypass the lens on the EX3 then? I would get interested in that setup if it was true.
Also putting some fast lenses on there would help DOF, the half inch sensor isn't *that* much smaller than a 2/3rds. f1.2 or T1.3 lenses could make a practical visual difference (T1.4 on 2/3rds same as T1.2 on half) Very interesting though... cheers paul |
Phil's review is Great!
|
Can you point us to Phils review of the EX3?
or is it not up yet? |
Phil Bloom,
Not sure how long you will be in Vegas, but it would be a shame if you can't take a day to check out the Grand Canyon while here..... I promise you will thank yourself if you take one of the heliicoptor rides out to the canyon... might not be cheap, but it will be a memory you will never forget :-) |
If Phil is still in Vegas it's still really early there now, so lets give him a break.
I'm sure getting the review up is his highest priority on Sunday morning! George/ |

The EX3 will be almost twice the price of the EX1.
It's really at a different price point. EX3 is an EX1 with detachable lens, so unless you plan on buying more lenses, this will also up the price. I'm real interested in the SxS hard drive recorder, although I'm blown away Sony only offered it with 60GB.... What the... Hard drives are cheap! PHU-60K SxS Professional 60GB HardDisc Recorder. Also, what I really want is an EX1 that's not riddled with various issues. I'm not understanding why the EX1 has so many issues, it not like they has never made video cameras. Having said that, let's hope the near future software upgrade addresses these issues and adds enhancements. |
