Pentax Q7 has bigger sensor
#1
So far Pentax Q cameras use a 1/2.3" sensor. 

Interestingly Pentax will go for a 1/1.7" sensor in the upcoming Q7.

The crop factor will therefore decrease to 4.6x. The 5-15mm f/2.8-4.5 will then translate to a 23-69mm - quite attractive then.

 

Actually I liked the Q quite a bit so maybe I will give it a try once more.

What would the new diffraction limit be?  The 1st gen sensor was around f/5.6.

 

The fish-eye should be closer to 180° now!

#3
I reckon f/5.6 will be Ok on the Q7.  However, that's still equiv to f/25 on full format (DOF-wise).

Thus I still wouldn't go beyond f/4 if possible. Why should you anyway (assuming that you got a decently centered lens).

#4
That is kinda nice, bringing it upto the level of the enthusiast compacts.

 

The 1st gen sensor would show diffraction loss after f2.8, anyhow...

#5
Quite cool limited set.

Although I would prefer quality lenses over the toy lenses.

#6
Yea this was announced 3 or 4 days ago; but no one started a thread Sad I forget what size sensor do the larger compacts use like s100 ?
#7
The S100 has the same sensor size.

FWIW, the Q7 has no AA filter but I doubt that this is unusual in this sensor class.

#8
DIdn't someone - sony ? fuji? introduce a s100 competitor with a larger sensor ? I guess it was probalby sony they seem to do that sort of thing. The Q7 is amusing (at least the pictures on a key chain ) but I'm at a lost because when you add a lens it doesn't seem very pocketable (at least in the pictures) - it seems larger than sx240 or similar.

#9
In answer to previous post - The sony rx100 has a 1 inch sensor and the q is tiny . To compare size go to the camerasize site.
#10
The larger sensor camera that you are probably refering to is the Sony rx100. Use camerasize site to compare cameras. For me the Q7 makes the q system really interesing. Might buy one.
