I think there are always going to be opportunities to see things differently through an optical viewfinder. The aperture is often different for viewing/composing, with the aperture shifting during the actual taking of the shot. Then the mirror flips up and you hope the sensor is perfectly aligned ...

Why is everyone doubting what the OP is saying? I don't think he would lie about this and it seems to me that the viewfinder is not representing correctly what the sensor is recording. Regards David Thank you, that is just how I am feeling about some of the comments.

........................... - but Walkeja has raised an interesting topic that hopefully someone will do a thorough scientific study on and present conclusive findings :wink: p.s. I'm surprised nobody suggested that the turbine blade moved between you composing and taking the shot :shock: :D Here...

Can see the hedge line difference, can only think of setting up on a tripod and paper on the wall, set up with it cut to 3:2 format and fill viewfinder take the shot see what is produced. Have you previously tried experimenting with the sensor shifting function? still in the last position? I woul...

Composition adjustment is a saved item in the custom menu 'memory' subsection ....you need to actively reset the sensor position , or not have the memory item checked, in order for the sensor position to restore to fully centred. The default for composition adjustment is 'on' in the memory setti...

Good point there Nigel. A composition adjustment would move the sensor, which would therefore create a difference between the optical preview and what the sensor actually captured. Worth checking it out.

I'll credit inFESTation just above me for thinking of it first :) I'm surprised that the default is to retain a composition adjustment .....I would have thought that after switching off the camera it was more logical to restore the centred sensor position.... It's over to you now, walkeja, to...

K50 pictures completely dark
Hi Everyone! And thanks for your answers. @SteveLedger: It's evening here now, too late for outdoor shooting, but yes, inside the room in LV mode the display is rather dark. I can see the lamp's bulb although but only if I point to it directly. Is it sensor problem or else?.. Thanks. @richandfleur...

K50 pictures completely dark
I'm also having the problem with dark pictures. My son can get it to work in manual mode but I need the auto..😊 I updated the firmware yesterday, formatted the sd card, did the dust cleaning and a few other menu items but it didn't help....I'm currently reading through the forums to see if...

b&h take on K-3ii
It does concern me though that in a balanced review there is no mention of AF performance at all, which as we know is the one area that has aspects which lag behind the competition. Dave Does it? The k-5 Mkii has the best low light af of any system. My D750 is supposed to af at -3ev like the k-5m...

Full frame or not ???
Pentax only has smaller APS-C sensor digital cameras presently, as Jonathan-Mac mentions, and these only use the middle area of a FF lens. Therefore you can use any Pentak K FF lens on the camera, which includes the older film era K mount lenses also. Later on, once the FF camera arrives from ...

Full frame or not ???
The advantage of buying a full frame lense now for an APS sized sensor is that when Pentax do eventually make full frame cameras your lense will still be compatable with them if you decide to upgrade as explained by richandfleur. You will in effect be future proofing your lense collection.

Some say that a lens such as the one you cite will be better on a camera with an APS-C sensor since you only make use of the "best" bit, i.e. the middle. The bonus with using a telephoto zoom is that you get more for your money, focal length-wise. For example, a 300mm lens "becomes" 450mm. Of co...

I too have not felt very convinced by such focal length 'equivalent' comparisons. This often translates into statements such as 'aps-c has the advantage for wildlife' .... The supposed advantage being that (for example) you only need to buy a 300mm lens rather than a more expensive 400mm for FF. ...

Full frame or not ???
I'm not so sure ... Perspective is really a component of the focal length. As such it is another constant, so doesn't change with sensor size. Perspective effects are things like how flat or deep something appears ... So a face portrait looks good in the range from, say, 70mm through 135m, due to th...

Oh dear. Perhaps I should have said 'field-of-view' instead of 'perspective'. The main thing that I wanted to convey, was that a lens's focal length remains the same, regardless of sensor size.
