What does it mean when I hear of (can't remember where) of Sony's 'Lossy Raw Files?

Thanks, I'll give that a good read later.
It was this that put me off buying an A7, as I never use jpeg.
The big question is, does the 11+7 bit RAW file compression make the Sony A7 series cameras not worthy of consideration? Is it really a deal breaker? I guess it depends on how important pixel-level performance is for you. For 90% of photographers out there, the 11+7 bit RAW file compression won’t matter, as they won’t be analyzing images with a loupe at 100% or higher magnifications. However, if you are genuinely concerned about pixel-level image quality and want only the best results at full resolution, you might want to hold off on the Sony A7 series cameras.
Very much so!

Park Cameras, you can get the Sony A7 + kit lens for £899. That's only £20 more than DigitalRev..
You'll need this code though - "MNL-A7-100"
Not sure what the point of the image post was considering it has nothing to with raw files, now I'm back to a d750 I wonder why I made the big mistake of selling it. We all have different expectations.
Nothing to do with raw files? I'll get to that but first, maybe you were swayed by the charms of the A7 and disappointed with some aspect of DSLR ownership? Whatever the reason the A7 series isn't for you and you make the point, often and repeatedly so I'm happy that you're going back to something that suits you better.
The A7 series is for me and whilst I can sort of see your point(s) and when reading your posts and the linked blog I was thinking about the plus and minus points of the A7 series and whilst I accept that the raws (you see, I get the point and I waffled on about them in my post, did you see?...) could be an issue for me they're never been a real world or even a test scenario issue and when considering that fact (it's a fact for me) and balancing it against the major plus points... the size of the system and the image quality and for me the ability to use manual lenses... I'm personally not put off by what for me is a non issue. Compressed raws. I've read reviews and blogs in the past and I have to say that I've mostly and possibly only read that the compression is a non issue and that's what it's been for me so far. Even your linked guy says it wont be an issue for 90%.
Good luck with your DSLR.
Seriously, why are sony using LOSSLEY Raw files? is it a limitaton in mirrorless tech or something?
edit: Dont mind Twist, he likes to chop and change gears
He will go back to an A7 series camera soon i reckon hehe and maybe add a 5ds too!
Well, give us a shout with a price when you go past! I'm sure I can find someone passing through an airport sometime soon..
Edit: According to this - http://boutique.heathrow.com/index.php/products/technology/sony-a7-detail. £50 difference. Not as much as i'd hoped, but ah well.
Yeah it is, but for me, half the reason is to go mirrorless is weight. So buying a II sort of negates that. I'd rather spend the money I save buying a normal A7 on better glass - cause Sony glass ain't cheap..
My thinking too on cost actually, I'm off to London in an hour will see what the prices are like at Edinburgh Airport, might nip into Park Cameras store off Oxford Street and see if they have that deal on, if not Jessops are doing a free bag and have stock.
May i ask why it's holding you back?The Raw situation is the reason I haven't and probably won't invest in Sony. If it's due to sensor tech, which some say is why the option hasn't been added in a firmware update, then I'll wait for the next incarnation and see what that brings. I'm in no rush.

It seems that it only loses a tiny bit of detail in raw but not enough for 95 percent of toggers.
So long as you can adjust levels, WB etc etc what am I missing.?
Well I don't think I'm fated to have an A7. .. bought one in the airport and its totally dead either the battery or charger is goosed. Will be going to a Currys store for a refund on it tomorrow. It's probably missed it's chance as I've been out tonight on Bankside in London with the D800 and 24-70 and loved it....
I would say though that of all the compact systems I had a play with in the airport the EM1 by far felt the best nice weight in the hand and if it wasn't for the m43 sensor I'd have one... thinking a change of strategy from aiming to replace my D800 to accompanying it might be an idea.

A few queries.
1....Do many of you use Canon EF lenses on a A7R using an adaptor?
2....Does the adapter effect the effective focal length?
3..Is the autofocus with the said adapter really as bad as I have read?
4. What is Sony/Zeiss best offering for a walkabout/landscape lens?
Surely question 1 is subjective? Anyways i got a 55mm prime zeiss. Will let you know how I get along.
There is some new primes coming out soon
3..Is the autofocus with the said adapter really as bad as I have read?
4. What is Sony/Zeiss best offering for a walkabout/landscape lens?
That's certainly shot the Canon Sony adapter theory out of the water.
It looks accurate but rather slooooow. It may be ok for static subjects and landscape but may not be suitable for casual walk about shooting, but manual focus isn't lightening fast either
You could always sell off all your Canon kit. That's what I did and I haven't regretted it![]()
I have 3L lenses and a Zeiss 21mm...I'd lose a fortune getting rid of them all.
Bummer! How much was it? I also had a look at Olympus & Fuji (I originally planned to get the Fuji) but i've had cropped sensor cameras for the last 8 years, it's about time I moved to FF!
Think i'll go for the Park offer.
Yes the Zeiss is manual....21mm f2.8
