Thanks for all the info, I now have even less idea what I want/need! [but more lens knowledge]

I an shying away from non 'A' mount lenses, but do wonder if having one would force me to learn more about what is happening with my camera, and they are cheaper! ...

Pretty much gone off topic,so thanks and I'll ask any more questions in the correct forum.

Andy

Cheers...very helpful!

Thanks mowog, I'll keep looking for a 24mm for now. Spent too much time on ebay today!

Must it be 24mm?


I've no idea! As I said, I'm new to this. My first purchase was a Pentax 50mm 1:1.7 which has proved excellent, even with my limited talents.

I now want a prime lens that gives me a wider angle, I think 24mm is the best option, but I haven't actually used one, just set the kit lens to various settings. If I had a little more money I would buy both and compare them.

Do you have a price in mind?

Andy

That is the one that I'm considering...is that a fair price?..I've only had the Dslr for a month so I'm new to prices.

Andy

Seen it. Is that an acceptable price?..I'm tempted but wanted to check that I'm not paying too much / could find one here for a good price first.

Andy

Hmmm..I watched a Miranda go for £36 a couple of weeks ago, then tried to bidnapper one last week at £50 and it went for £56! What was your limit for the Miranda if you don't mind me asking?

28mm versions seem more abundant..but still go for £45+

I noticed the post of a £40 Sigma this morning...

Hi,

Does anyone have a nice example of a 24mm manual focus with 'A' lens for sale? Not set on a manufacturer, but am after a 'well known' make at least.

Thanks

Andy

Thank you. I'm learning more each day. 24mm is looking quite desirable!

Hi,

I have been comparing focal lenghts of my Canon S90 and my K100d.

Can someone explain, or send me to a page that explains the different uses of focal length markings?

Now I understand that my K100d has a crop factor in relation to film, and that my 50mm prime has an 'effective'focal length of X1.5 equalling 75mm.

With all that in mind I have compared my Canon S90 with the K100d and 50mm prime and to acheive the same frame on the Canon it tells me it's focal length is 85mm.

S90 reviews refer to it's focal length as '35mm equivalent'

Is all this correct/does it make sense?

The reason I'm doiong all this is to try and work out the effective field of view that I will acheive if I get different primes for my K100d...

Is the Canon showing the 'correct' reading?

If I set the Canon to ~40mm will I get a similar field of view to the 24mm prime that I'm after for the Pentax?

Any help appreciated,

Andy
