Interesting discussion.

I would have thought that there is no right and wrong. As the object of our photography is to enjoy expressing ourselves with image making, does it matter as long as we are doing it the way we want to?

Maybe it fits in with the way people market in Japan, the rest of Tokyo certainly looks colourful enough.

The serious amongst us can buy black. Some wedding photographers might buy white (I've considered it for that purpose) and red and blue might just be fun colours.

Time will tell, but there is a school of thought that says that any publicity is good publicity....

I would want to encourage newer members to enter, not exclude them.

Actually I wrote "in a big way" so I don't understand your mis-quote.

Please elucidate. :

This will get Pentax noticed in a big way.

I see SRS have all four colour on their website, available for advance orders.

That translation is so indecipherable I think it's of little value TBH.

The 28mm lens is the same as the one tested here, just re-released as an A series version.

The trouble is these can be expensive lessons to learn, and I too have sold a lens only to miss it and then have to buy another.

It would seem a 18-150mm would be perfect, but there isn't one.

I suspect the problem with images being poor over about 150mm is simply camera shake because the aperture reduces so much and the shutter has to slow down. Try on a tripod to be sure of this.

I would be inclined to go for the now classic kit of 18-55mm (or 16-45mm) and 50-200mm. This will be compact and effective and also not particularly expensive. If you go for the 17-70mm on its own then you still need a second lens anyway to extend your range.

I absolutely understand, but we have to remember that people are entitled to not be involved if that's their wish. Not everyone wants to be more than just an occasional contributer, and that's fine.

In a similar vein, some people join ADAPS just to enjoy the facilities on offer, others become committee members and want to help to run it. There's room for everyone!

You already have an excellent lens in your Pentax 18-250mm and I wonder why you want a less versatile one to replace it?

I'm guessing it might be a fsater aperture you are looking for, or maybe a more compact lens?
