nd it needs adaptors like yesterday. Why does it need adaptors? I mean the IQ is probably not the best and since you've lenses that need an adapter i also assume you've a camera that has the right mount with better image quality, so why do it? Also the sensor is very small so it change the angle o...

what is your tip when using manual focus under f2.0?
Hi. I have pentax a 50mm 1.4 lens and am experiencing difficulties in using manual focus. Especially, under aperture 2.0 how do you use manual focus? any special tips? If the red focus light and the beeping sound is not working accurately, is there any function to turn it off? I am always amazed...

The "red focus light" does not indicate you are in focus - it only shows you where you are focusing. The green hexagon indicates focus has been achieved. This does seem to cause confusion sometimes. When manually focusing I don't use the focusing aids at all, never did, and just visually focus us...

Live view - perfectly focussed, but a bit awkward to use unless you're using a tripod. Split screen focussing screen - usually, but not always, perfect focus, but convenient to use. A bit scary to install the first time you do it, a doddle after that. There are also people grinding down Canon...

Doesn't a split screen affect the metering?

Doesn't a split screen affect the metering? I'm pretty sure it does, especially spot metering.

Live view allows you to zoom in to check focus.

Doesn't a split screen affect the metering? There are conflicting reports that it affects spot metering. It seems to make sense that it would! Can't say I've noticed it myself, beyond the normal occasional spot metering cockups which I get whether or not I have a split screen installed.

what is your tip when using manual focus under f2.0?
Split Screen - can't say I've noticed it affecting metering (I find even the standard screen is off on the K5 so I pretty much have -1/3 to -1 EV on all shots depending on the lens and situation I'm shooting in). When manually focusing you need to be aware that there is a 'zone' of 'in-focus' whe...

I have a pentax magnifying eyecup on my camera pretty much permanently, and I think that helps a bit, as I tend to focus my 50mm manually, especially when using a big aperture. Regards

what is your tip when using manual focus under f2.0?
I've had this problem with my k-x, maybe partly because of the pentamirror being a little bit darker than the pentaprisms I was used to on previous cameras. I experimented with a split image screen, not so good with slower lenses and a bit of a nusiance for macro work, but otherwise good. I'm now ...

The "red focus light" does not indicate you are in focus It does flash when the camera thinks focus has been achieved though

what is your tip when using manual focus under f2.0?
Unfortunately the screens of most 'crop, sensor cameras are a bit small compared to the full frame ones of older film cameras and the professional DSLRs and quite fiddly to focus by comparison, especially given their shorter focal lengths for a given angle of view. I don't think there are any tip...

It does flash when the camera thinks focus has been achieved though Only the green hexagon indicates focus has been achieved. No the little red square in the viewfinder flashes ( blinks) when the camera thinks focus has been achieved and then extinguishes.

what is your tip when using manual focus under f2.0?
Sorry, Smeggypants, but the instructions quite clearly differentiate between the red point which indicates where you are focusing and the green hexagon that indicates when focus is achieved when it stops flashing and the camera beeps. It's actually quite hard to prove the point as the camera lock...

The beep also indicates in focus.... goes right back to the ME-F. With some lenses the red square is as good as you will get. It's unlikely that a 28mm f/3.5 can be turned precisely enough to get the green hexagon at over 3m :shock: There's only 5mm on the focusing scale between the 3m mark a...
