chill guys, no need to get so technical!
enjoy the beauty of a V.

I shot frames after frames without a winder... on a good tripod and a steady wrist, the camera is easily winded without too much movement at least I can do it.

"As for chromatic abbrevation and lens resolving power with regards to tolerance on film and digital back, you can read the schneider white paper on digital lenses and conventional lenses. May be I did not express well but the white paper explains."

What I am trying to say is the film lenses, C, CF, CFI, CFE are optimized for film inside a film back not digital ccd in a digital back, that is why CA surfaced more prominently, except for the latest CFE 40mm IF.

CCD has only 1 plain compared to film which virtually has 3 due to the layer design. Hopes this clarifies.

If anyone has a better english or understanding can help out here would be good instead of misconceptions......

Where is your proof?

Because if what you say is true, then all lenses built before digital, all canon l lenses, all nikon pro lenses, all contax, all leica lenses-- should be thrown away because they will cause ca on digital. Strange, but I haven't seen anyone else in the world say that we should all throw away our lenses. Of course the lens makers would be happy for everyone to buy new lenses, but can you cite any independent optics experts who say we should not continue to use our existing glass on digital bodies?

"Is the difference between 1/500 and 1/400 so significant that you cannot live with it? 10-20% failing rate because of this? You must be a damned good photographer then. Because for years and years, pro photographers have been using Hassys with slide film (same lattitude as digital, or even less) with no apparent problems."

How sure are you that all year round they have no problems? did they inform you? any statistic to support? or was it a misconception that you assume?

If you think Hassy lens shutters so unreliable, how did they get to No 1 position, used by tens of thousands of pro photogs for slides? In the film days, MF cameras and lenses cost tens of thousands of dollars each, if they weren't reliable, do you think pros are stupid enough to buy them?

Or are you telling all to accept the difference between 1/500 and 1/400 and live with it when you pay for lens range from of US$700-3000. Live with it since you pay so much???

Your basic assertion-- that mechanical shutters are so unreliable they cannot be used with digital-- where is your proof?

Second hand CFV cost about US$6000plus, V96C US$3500plus minus, 500CM kit US$1300-1600, servicing say S$500-1000.

You must shop at the wrong places? People practically giving away 500CM's at US$5-600 on eBay you know. Here's an example with A12 back and kit lens at US$541. And it's cheaper than that on personal classifieds. Servicing at $1000? Who are you kidding? Why are you trying so hard to exaggerate?

You don't like manual cameras, you think electronic shutters are better, just say so, no problem. But to put out misinformation and misconceptions to support your case? It shows what you really are.

So about US$7000-8000 for CFV, US$5000-6000 for V96C for start than later you may add a 150mm or 40mm for US$500-750 or US$1600-2500 so have to set aside close to US$10000-12000 for CFV and US$8000-9000 for V96C.

Lets factor in another US$2000-3000 just in case it need to send in for repair etc. Worth it??? You guys decide whether is cost effective.

If we can't trust your figures for the camera, how to trust your figures for the back?

So a H-series say the H3D II 31mb for S$23k is it worth all the worries or a Mamiya M22 for S$14-15k for example.

How to trust your figures? Where's the credibility?

It is the system that one has to consider after buying the camera. Lets face it V-series is really just for film and you are compromising to use with the digital back. If not why Tim Flach and Alec Soth move from V-series to H-series.

I don't know these two characters and wouldn't know why they moved. But certainly a working pro is entitled to move up the technology curve if his business can support it. Doesn't mean the previous equipment can't take good digital pictures, esp for non-working pros.

I didnt say that C lenses or CF lenses cant use for the digital, it can but you will see not good results.

Where is your proof that CF lenses cannot give good digital results? Do you have controlled tests?

===

Lets see...

You focus on the small things and not the big things. Like possible micro-movement of the camera when cocking, so no good for digital. Like possible minute shutter speed variation of mechanical shutter, so no good for digital. Possible chromatic aberration caused by older lenses, so no good for digital. All the while ignoring the many many satisfied Hassy digital back users all over the world and the thousands of Hassy digital images available for you to pixel-peep if you want them.

You exaggerate Hassy V used prices, repair costs and serviceability. You highlight old issues like vignetting on old bodies and misrepresent that it makes them unsuitable for digital, conveniently forgetting that with a cropped digital back, viewfinder vignetting is not an issue. And you also ignore the HUG guys who gather at Shriro every month and who are getting splendid results from their V bodies and lenses on both digital and film.

So who is picking bones?

 

[Xtol19]

500 series were built at the time for film so the tolerance of the back is totally different from digital back.

All must understand that lenses built for film has different tolerance in the focusing plane as film has generally been 3layers and not as flat and digital is a single layer and flat.

So lateral and chromatic abbreviation will surface when using film lenses i.e. C or CF or CFE lenses on digital back. That is reason why Hasselblad has the DAE technology.

BS BS BS.... So-called "digital" lenses are optimised for digital, you say? Do you know what DAC technology really is about? It's Digital APO Corrections for chromatic abberation, distortion and vignetting.

Guess what this means? Your so-called digital lenses also have CA, distortion and vignetting-- just like so-called "film" lenses. DAC is just software processing in camera to remove it.

So are your so-called "digital" lenses really "optimised" for digital? If so, why does the camera need to run software corrections to remove CA, distortion and vignetting?

"Digital" lenses my foot! Reminds me of Hoya trying to sell "digital" filters, you're like one of those who actually believe the marketing BS from Hoya!

Here are some points for you to consider.

CA is not a property of a so-called film lens. It is something that a so-called digital lens has just as much. CA is caused by different wavelengths of light not focusing on the same plane. Affects both film and digital. Best way to avoid/minimise it is to use APO lenses, like the 250 SA, which are supposed to focus all colours onto the same plane. Of course, one can also cheat by doing Digital APO Corrections to simulate the real effect of an APO lens, when in fact your so-called digital lens is not a true APO lens.

And frankly, since DAC is an in-camera software correction, one can also buy 3rd party software to correct the image in PS, if desired. What's the big deal?

So please, no more BS about "digitally-optimised" lenses please.

Just heard from Denis;

The latest buzz for the next HUG is on Tuesday , 1 st December 2009 , 7-9 pm at #06-01 Shriro House .

They will be having Edward Hendricks , an interior photographer to share how he uses the Hasselblad HTS 1.5 , tilt shift adapter in his daily work .

Also , TS Sim , who has tried using this in his work instead of a 4x5 .

There will be the usual food and drinks supplied .

And a Lucky draw .

both my friend and I are interested in Hasselbald, can non-users attend as well? or is this only for owners only? I'm looking to learn more as I search for a good setup that's within budget.
