It's not that small either with a lens. The 24mm on this page link
is absolutely massive. (posted by Pentaxophile).
It's a good job that photographers in the 60's didn't choose cameras based on plan views and thicknesses Leica's would have won and SLR's would never have caught on. Pentax wouldn't have survived. The Hasselblad would have been far to thick and the Rolleiflex would be the King

Comment by Algernon posted on Pentax 1.7x AF Adapter at 08/02/2012 - 11:21
Picked one up for a bargain £143 plus £10 postage last week off fleabay
They were being sold on this forum for £250+ not long ago. They are a good TC that actually works with most lenses, which isn't the case with the Tamron/Kenko alternatives. I've got a Tamron 2x that works with the Sigma 150-500mm but not with the DA*300mm. Can't figure out why because it's got 7 contacts either side + Pz contacts Possibly something isn't touching.

Only costs £260-£350 link and you can now use Sony DSLR lenses just like you can use Pentax DSLR lenses on K-01 without any adapter.
We won't mention that because the Pentax might sound better
We also won't mention that you don't need to buy any extra lenses

The downside to adopting the K Mount is that it defines the distance between the back of the lens and the sensor, known as the flange back distance. This is 45mm for K Mount cameras, which is significantly deeper than in rival CSC systems such as Micro Four Thirds (20mm) and Sony NEX (18mm). As such, the K-01 is a lot chunkier and a little heavier than rival CSCs, at 59mm deep and 560g without a lens. Then again, the Sony NEX range's short flange back distance is arguably the main reason why these cameras sometimes struggle to achieve sharp focus across the entire frame. Most other CSCs use a short flange back distance too, but pair it with a smaller sensor, which avoids focus problems but limits their low-light performance.
It seems likely that the K-01's relatively chunky body is a necessary compromise for achieving both low noise and sharp edge-to-edge details – something of a Holy Grail for CSCs at the moment.
That's a very positive comment.

So the Sony NEX 5N has an 18mm reg. distance and the body is 38mm wide which means there is 20mm from the sensor to the rear of the camera. The K-01 has 13mm from the sensor to the rear of the camera, but it has SR built into that The Sony needs SR in the lens (expensive).
Assuming someone like Sigma do the same lens for both cameras.... say it's a 50mm FL + say 30mm at the front for lens thread etc. = 80mm
The overall length of the Sony will be 80+20 = 100mm and the
K-01 will be 80+13 = 93mm
So the K-01 with the same lens as the Sony is 7% (approx) smaller than the Sony and has SR...... I can't see that being a disadvantage
I think that reviewer along with most other reviewers needs sacking
Then again if your going to use the camera without a lens .......

Well the games afoot. Sony have announced a dust and moisture resistant 500mm f/4 along with a new FF DSLR. Also 4 metre min focus. So there will be plenty of competition for peoples long lens money.
