The A will be on the aperture ring of any automatic metering manual Pentax lenses.




The A on most I've seen is green unlike the one in the picture above.


SPV, you must have this:

The following is(are) the automatic version(s)

Amazed by the number of different versions of what is almost the same thing apart from the aperture range. Varying weight, construction and glass layout...

Wonderful, thanks for that

I was wondering what the following are:

I have taken an educated guess at two, but AL still eludes me.

ED: Apochromatic Glass Elements (wavelengths refracted equally)
AL: ??? I have no idea...
IF: Internal Focusing

The adapters can be found at Maplin:

Put in your postcode and it will check stock at your nearest 5-8 shops.

The reason for the price is that it needs a bridge chip to convert CF/SD electronic pathways for correct read/write. They have a very different pin layout and electronic transfer system, so it isn't just some wires and case.

B is the odd one out... ???

I think A and C are Canon from looking at the colours recorded.

B is the Pentax, from what I've seen it tends to be bright.

Don't like C, but it may be the light/time of day in the picture.

Don't Hoya want to sell off Pentax's camera business and keep the lens dept?

Some ND filters are a good idea. Unfortunately I can only find 3/4 1/2 and 1/4 filters and I's like to get some even lower light levels for very long exposures. Anyone know where I can get them? Something like 1/8 or even less transition.

I have a relatively good tripod, but heavy, that I'm happy with. I'll get a lighter one eventually.

I have a UV, ND and CP 55mm for the Fujifilm camera but I've noticed that they cause AF problems in strong light (they are not multi-coated). Now I was lead to believe that the anti-reflection multi coating was standard, only to learn later that it is only on the more expensive filters. Will a lens hood be good enough to fix AF and reflection problems?

EDIT: I don't have the camera yet but already downloaded the manual from Pentax

Excellent, hopefully I'll post some on the forum once the kit arrives. I'll have to find somewhere to go for a walk... Probably out on the Pennines. Really looking forward to having a DSLR.

Ok, I think I'm going for the following initial set:

Pentax K10D
- Pentax SMC 18-55mm (27-84mm) f3.5-5.6 DA A
- Pentax SMC 50-200mm (75-300mm) f4-5.6 DA ED

UV Filter (mostly lens protector)
Circular Polarizer

Waterproof backpack

Plenty of SD cards...

Can anyone think of anything else I may find useful with a DSLR?

That is very good to know and I've not seen it mentioned anywhere before.
