Actually the Schneider Kreuznach and Mamiya Sekor leaf shutter lenses go up to a max speed of 1/1600th sec, flash sync at all speeds of course. The Hasselblad sync up to max 1/800th and the Leica S up to 1/1000th. The blad is only leaf shutter however and the pentax only focal plane shutter.

If you have the lights that can do it, a p45+ or newer back, and are hard wired or using a Profoto Air or Skyport trigger, yes, it is possible to get 1/1600th.  If you're trying to kill the sun, yes 1/1600th matters.  But if you're trying to freeze motion, you're actually better to shoot with faster lights at a slower shutter speed.  No LS lens, you're at the same 1/125th sync speed on the Pentax or the DF+.

There are manual focus -A LS lenses  like the 135mm LS for the Pentax 645 and any Pentax 67 LS lens can be shot via adapter  (full manual).  Pentax has promised new LS lenses, so this issue should go away.  Pentax 645Z also can do HSS with their P-TTL speedlights - so you can 'sync' at up to 1/4000th of a second.

I just didn't like the feel of the Pentax, looking into the viewfinder was like looking down a straw, and it just felt plasticy and toyish ... The service reputation for Pentax was poor at best .. I found that even when looking at it, the guy in the shop wouldn't even put a battery in it for me ... so I just had to play with it dead and just manual focus it in the shop.

The winner for me was hands down the Phase One "SYSTEM" ... I intend to buy an Alpa technical body and then I'll be able to use all the top quality Rodenstock lenses out front with the digital back on.
Service from both Phase One dealers here in Aust was second to none, L&pFoto in Sydney and Specular in Melbourne.
They can take Schneider, Phase One and Mamiya lenses on the body.
Aquatech also make a water housing for the camera too, which is my next purchase.
The back will hold it's value to some extent and I'll try and up-grade as time goes on to the IQ backs.

But for now the image quality of this camera has astounded me, of course it's inherent in medium format.
I don't regret for one second buying into an older sensor, it's fine for what I wanted, low iso, the overall system of the Phase One is what swayed me .... to me the ONLY thing I saw going for the Pentax was the new sensor ... and it made it a hard decision, but the versatility and solid build of the Phase One system as a whole was what made it a no brainer in the end for me.
Oh and YES Danielle .. Capture One Pro 8

There are things going for the 645Z, but they only matter to certain people.  The sales and support channel is better with Phase or Hasselblad based on their existing channel.  There are existing sales folks whom have no business dealing in medium format gear, and it sounds like you found a few.

Strong points for the Pentax over the PhaseOne P45+:
- High ISO (100-204,000)
- 3 fps
- Live view with articulating screen and focus peaking
- Dual SD card slots
- Weather Sealed body and lenses
- AF points and tracking ability

Strong points for the Phase over the Pentax:
- 1 hour exposure time
- ISO 50
- lots of Leaf Shutter lenses (1/800th flash sync)
- CaptureOne & tethered workflow
- Technical camera functionality

As a Capture One pro 8 user, their website still suggests only file support (no tether) for all pentax units. The 645 system is not listed however.

My bank account currently says no regardless but this workflow issue is a real problem to me. I need tether support and I don't want to go back to lightroom. Nothing against Lr but capture one works for me. I wonder if they'll support it fully at a later date. Otherwise I'll be going Mamiya or Phase One (it's when, not if).

If anyone knows more than me, feel free to educate.

No Capture One support at all - files or tethered.  Don't expect it as they are a competitor.  But it should help depress 40MP back prices - Credo 40's are like $12k in a kit.

As much as I want to see 35mm FF at a higher pixel density, the technology that goes with it has to be spot on.

I'm not sure a 50MP Canon will shift my lust for the 645Z, but it'll be interesting to see what they have come up with :)

So the Viglink bits inline with the text isn't ideal, interesting to see if anyone else notices.

There are lots of camera bag threads that the OP really should look at.  The trade off is that any bag designed to be heavily adjustable will not have a lot of structure or padding to it.

Photography Technique / Re: Aperture for total sharpness?

Is the OP trying to recreate the image being linked to?

Proper technique is critical, and shooting from 1m isn't going to give you the results you want.  Back up (lots) more, shoot both on the long end of the 70-200, with IS off.  Check out http://www.dofmaster.com/dofjs.html

EOS Bodies - For Stills / Re: POLL: Do you need 1/8000s shutter speed?
« on: January 07, 2015, 01:00:12 PM »
Getting CMOS to ISO50 but limiting to 1/4000th is a trade-off lots of folks would take.

Remember, medium format cameras have been limited to:
 1/500th - Hasselblad V/500 series, lots of LF copal shutters
 1/800th - Hasselblad H series
 1/4000th - Pentax, Mamiya (Phase One) Focal plane shutter

You should see how small that slit is and how fast it's moving to do 1/8000th, especially across a FF sensor.  APC is so much smaller, going a much shorter distance, allowing for smaller moving parts.  The only way to get faster is with a fully electronic shutter.

I cheat - I've got a UPS Store mailbox, only address I ever need.  Moved multiple times, no change of address fun.  No stolen packages, no missing a delivery, it's there, and they send me a text message when I get anything.  LensRentals packages show up and they ooh and aah with me as I make sure it's all good.  Even had a set of 4 tires sent there :-p

It could be worse - there was a carrier in the UK whom shut down incoming for a few days to catch up a week or so ago...

Take a look at the MindShift bags from ThinkTank - the slide around to access your camera plus a lens is pretty slick.  Pop two clips to allow the belt to swing around, rotate the bag to the front, unzip.

OP: Since there is a lot of variable as to what ships when, worry about what you have in front of you.  The 5k iMac is a beast - and while I want one personally, it's due to the 4k video I am playing with.  If you're doing 4k video stuff now, then the new iMac gives you something you don't already have.  Otherwise, wait a few months and see what's going on.  No harm right?

Spending $5k on a camera system in any situation without prior knowledge and experience is foolish, I don't care what the camera brand is.  But some folks have money to waste, and there will always be Uncle Bob's of the world...

Bit judgmental comment I think. Perhaps she wants to start learning and perhaps can afford it easily. Would you have said the same if she had bought 5d3?

Yep, doesn't matter the brand or technology - there isn't any context of what experience or existing gear the person has.

Third Party Manufacturers / Re: Sony - Question of a Differing Variety
« on: December 08, 2014, 11:35:10 PM »
Here's the technical answer you're looking for - two different communications protocol methods on either side of the adapter, and you, in the middle have to make them speak accurately, quickly & reliably over many generations of gear.  Lenses, bodies and firmeware that have been discontinued will be used, yet you are expected to work every time.

Here's a bit on the Canon side of the equation, and ask yourself, at what price is making said adapter worth wild.

Technical Support / Re: Optimal processing platform of still images

Too many different tangents that could be had - starting with the PC/Mac debate.

The keys to best performance are solid state drives (SSDs), lots of RAM and a recent CPU.  Most folks don't spend the coin for a top end video card, but should.  With all the 3D stuff in Photoshop dependent on it, plus higher resolution monitors now available, the ability to drive a UHD or 4K displays is critical IMHO.

If you do a self build, go for it.  But if your day job isn't in IT, go the safe route of buying a pre-built, or make friends with a local computer repair shop to do your build.  The computer is a tool, and if you're making good money from photography, dealing with drivers and upgrading components isn't the best use of your time.

Check out the WonderPana system - it has a CPL and isn't extremely expensive.  The thing is that the WonderPana also has the adapter rings to get down to 77/82mm.

I'm also invested in the Lee 100mm stuff, and I think my general point is this kickstarter doesn't do a good job of telling me why I want their product.
