Image problem
Cheers guys I just needed to set the picture template pixels to the sensor size and that`s got it. I will try DNG files instead too :)

Forced to use tav for studio portrait
It's better to make a mistake at iso 100 than iso 200. If I have to recover two stops, wouldn't be the noise equivalent of iso 400 vs iso 800? I may be wrong on this, just intuition I don't believe there is much difference in the dynamic range at 100 compared to 200 if this table from AP is to be be...

M42 adapter
I bought an M42 adapter a couple of years ago for a telescope attachment but tiny flecks of the black coating got onto the sensor and even behind the focus screen. A devil to remove as it was static so I would always now look at uncoated versions which I imagine the Pentax one is.

new features, head auto focus
Definitely . I’ve had too many group shots ruined with a background nicely in focus, and my foreground subjects blurry out of focus. Or portraits where the eyebrow or nose is in focus and the eyes blurry. Is that with full AF? Have you tried centre point AF with the back button, then compose...

Getting ready to sell up and need advice on a compact.
I can recommend the Sony RX100. I have a Mk1 that I carry around in my pocket when I don't want to carry the K70. It is metal bodied and has been dropped many times. The picture quality from the 20mp 1" sensor and the f1.8 Zeiss lens is first class and has a 24 to 70 zoom range. There have been...

Getting ready to sell up and need advice on a compact.
EPhotoZine's "Compact of the Year" for the past several years has been the Panasonic LX100. Similar spec to the Sony RX100 above but with a micro 4/3 sensor and image stabilisation (an important factor as we get older!). I bought one recently for under £300 second hand and am certainly impressed w...

Getting ready to sell up and need advice on a compact.
The most useful and effective compact I've found is the Pentax MX-1. The quality is excellent and it is easy to operate under all sorts of difficult conditions. Plus it has the familiar Pentax ways of working. If you prefer interchangeable lenses, then the Q-S1 is terrific and uses a similar, if not...

Removing Covid-19 from Cameras
Just had an e-mail from SRS re Covid-19. Their advice for cleaning cameras and lenses is: Weatherproof - Spray with a disinfectant solution that contains over 70% Alcohol, and dry with a towel. Not weatherproof - Wipe down the exterior of your product with alcohol-based sanitizing wipes. We re...

Removing Covid-19 from Cameras
What about surface tension: alcohols have about one third that of water - doesn't that make it easier for them to flow around WR seals? A wipe with an anti-bac damp cloth sounds better than alco-spray for cleaning the gear safely. Philip

Post holiday cleaning
Recently back from holiday which required factor 50 sun block and copious application of DEET. Inevitably some of this has transferred to my camera and lenses. Any recommendations on how to clean this off?

Infrared (R72) filter. Should you be able to see anything ?
The Hoya R72 should let light through from 750nm - and may let a small amount of visible red through. See: https://hoyafilter.com/product/r72_infrared/ You can use IR filters on many digital cameras. However, some have aggressive IR cut filters that will block what's coming through an IR filter. ...

I don't have my K-1 manual/camera to hand but suspect you're looking for 'Composition Adjustment' or something similar?
