My nephews new pup with an 18-55 kit lens.
I hope this works,I have never put a picture up before.

[quote:3496ace15f="Mongoose"]Matt, it deppends on how good the lens is.

A Perfect lens would perform best wide open, with angular resolution given by theta=arcsin(1.22*(lambda/aperture))


where theta is the minimum angular separation of two bearly resolved objects and lambda is the wavelength of light.



I was gonna say that

Are there any sites with high res samples from the 16-45?I have been looking but failed to find much.

I hope it is acceptable to post this in this forum

If you have the Schneider-Kreuznach branded lens then it's the mark 1 version... I checked the specs recently on the sammy website and the elements and groups matched the DA 18-55 mk 1...[/quote]Last time I looked there are two versions of the 18-55 on the Samsung site but the specs were exactly the same,the same as the Pentax Mk 1.
I have a Samsung branded lens not the Schneider.Really quite confusing.I rang Sammy Tech support,but they didn't know if the Samsung branded lens was different to the Schneider.That is half the reason I started this thread.Thanks all for your input.With your help I am sure I will get there in the end.

Many thanks for all the responses.There is a lot to think about and digest there and I will do my best to do so.Particularly interesting was the information on closing down the aperture at certain focal lengths,I was misguided in thinking that brighter is better.Strangely I was in Waterstones last weekend and noticed the book Understanding Exposure but did not buy it.I will be going back to purchase a copy.I have been greatly encouraged by the help you have all offered and I will try very hard to put the advice to good use.Goodbye LBA hello ECD (Experience Collecting Duty)Thanks again all.

I think that should take you to some photos for reference
Feel free to point out any big mistakes

Many thanks

Yes, you did help.Many thanks.

I have an 18-55 (possibly mark 2 ,it's from my Samsung GX20) lens.Is there a comparison site to show how much better a more respected lens would be?I am afraid of spending money on a sharper lens only to find out the softness I seem to see is due to my lack of abilty.To a person new to DSLR it is a lttle bit intimidating learning all the new skills. I do not want to spend time learning new skills that only accommodate the failings of a lens,if indeed there are any.I am quite prepared to spend time learning to use this setup,but would really not like to spend too much time chasing rainbows.I hope this makes sense.
Many thanks

Oh by the way,I think I know what LBA is, but would someone be kind enough to tell me what the acronym stands for Lens Buyers Affliction ?
