It depends how you work really. I use two batteries, rotating them and charging via the charger. Using a power pack instead implies charging in-camera, which takes the camera out of service whilst we're charging.

Actually with the DSLRs I use a three battery rotation, but then a day's shooting on a job could be quite a large number of shots.

It depends what you like I suppose, but I rather did like the bold monochrome. Very striking and dramatic.

The camera is also very striking. I always had a soft spot for the MX.

I finally decided to upgrade the waterproof compact, having enjoyed some success with the W90 in all sorts of situations where cameras were not really the thing to be using.

The W90 will be going to Amelia Jane Riley, my four year old Grandaughter. She was astounding with it when we went a couple of places and she asked for a "proper camera", as opposed to a child's one, so the W90 will be ideal.

The WG3, in slightly gaudy orange, now resides in my pocket and does the arduous stuff. Not had a chance to use it properly yet, but it's very similar in operation to the W90.

The one niggle is that there's no charger in the package, just a power adapter and USB lead, so I need a charger and extra battery. This is a really backward step for manufacturers, but clearly that's the way it's going to be in the future. Presumably it's all about costs.

I have a linear polariser (Hoya) in 49mm if that helps?

It should be a clean process.

Put the print face down on newspaper. Spray with the can held horizontally about six inches from the paper, first one way, then the other. Leave the print until the adhesive is dry, perhaps 1 minute. Then apply it to the board and roller it down.

When the session is finished, turn the can upside down and expel some of the carrier gas into a cloth. This keeps the nozzle clean and non-sticky for the next time.

Simply because it's a 50mm lens, not a 75mm. It behaves just like any other 50mm lens. If it were on a 645 camera it would be a wide angle. If it is on an APS-C then it's a telephoto. On 35mm film format it's a standard lens. But in all cases it has the DOF and other characteristics of a 50mm lens, regardless of what you put behind it.

Marking it 75mm is saying it's something it's not and basically dumbing down the information. Anyone who has only used APS-C will know their standard lens is 35mm and a portrait telephoto lens is 50 or 55mm. No conversion will be necessary for them.

I'm not going to deny myself the use of some superb lenses just in case the future holds something different....

If it does change, then that can be dealt with at the time, but it won't change the current usefulness of all those lenses in the range right now.

Payment received, filters will be in the post in the morning.

Apparently some academics think that there might have been life before the internet. It wasn't life as we know it presumably, just a thin shadow of existence as humans dimly looked out at a dull world.....

On the face of it, the difference is that you have the choice of switching to manual diaphragm on the Adaptall mount. There's no such choice on a Pentax lens.

There is however such a choice on Pentax M42 screw thread lenses, and perhaps these would help as an alternative. There are some amazing screw thread lenses.
