I suppose inbetweeny it is, being pretty much equivalent to a 50mm standard lens on film. Neither wide angle nor telephoto, but at least offering natural perspective.

When I think about it, Pentax have quite a few lenses hovering around the 35mm mark.

WEll done so far, extreme bravery award follows!

Have you remembered to compensate for the focus point of IR light? Unfortunately this will also vary with lens and with the focal length set on some zoom lenses as none of them are corrected for IR light.

However, perhaps if you use a prime lens you could set things up quite accurately?

I can see that there are various possible reactions to buying some lenses.

I think we should just concentrate on the lenses and avoid the speculation about whether or not I or anybody else can afford them.

I know the feeling, but hindsight isn't available in advance, sadly....

I suppose we can divide the standard primes first of all into three groups. Low cost (35mm f2.4), standard (50mm f1.4, 35mm f2) and the Limited lenses (DA and FA sub-groups).

Cost may eliminate the Limited range, if not then go for them.

The standard range is around the Nikon price level, so maybe a good choice.

The low cost range has one outstanding lens as the choice. You could try this at low risk of major loss, trading up later if you need to.

Thank you for explaining.

As it happens I am interested for various reasons, not least of which is whether or not the resolution and general optical qualities stand up to the rigors demanded by the K-5 sensor. There's only one way to find that out and I've been exploring it this week.

However, what I don't quite get is why bother to say you're not interested, you must be on some level otherwise you wouldn't have joined in the thread. I tend not to post in threads I'm not interested in.

We haven't even mentioned the 31mm Limited yet....

If it's a 35mm lens that's on the agenda, the SMC Pentax-DA 35mm f2.4 is both excellent and a ridiculously low price for what it is.

I used one recently for a fashion show and it was brilliant. Sharp, free from flare and snapping quickly into focus. For £135 or so you can't really go wrong with this one.

You need to sign papers to get a Fuji IR camera. You can still get one, but the fact you have it is registered at least with Fuji and the dealer you arrange it through.
