Hi
This photo looks clear when you view it at this size :

but when viewed at the original :

not so clear , is this colour fringing ?

this was taken with the Canon 400D, but with the 18-55 mm kit lens ,

IF i get a better lens will this not be as noticable, or is this an effect
you will always see when image is 100%.

OK sorry , links are now fixed ...

its just a bit soft, better lens will help, the first is clearer cos its not as detailed so ya cant really see the softness.very common

Thirdfox

Looks like general softness of the lens - I see you're using f8 already... maybe it's time to upgrade your lens if you need a sharper lens.

But looking at an image at 100% on a computer screen is quite different to printing out an A4 size print. You may not need a sharper lens if you don't need to print at large sizes...

The kit lens is at fault here , generally its quite soft , almost any other lens is better than it. A cheap alternative is the 50mm 1.8 , which can be had for less than 100 euro and will show you what good glass can do.

Useful thread for a newb like myself....was wondering while I bought the 50mm 1.4 for gigs what is a decent budget cam for walkaround....
I too have the 18-55 canon and the 28-200 sigma.

Is that Portmarnock btw?

jackdaw

OK, so this is normal with the 18/55 kit ?

what sort of price would you be looking at to get clear results at 100% ?

for a lens of similar range =?


AND ..

am thinking of getting the Canon 70-300 f4.5/5.6 IS USM

its about 380 Sterling on ffordes.co.uk

and its not Portmarknock !!
It's Formentera , Spain ..


I'm hoping this lens won't be as soft ?

would be great if anyone could post images taken with this lens .. epecially at the 300 f5.6 end ...

50 mm 1.8

What about that sigma 70-300 that people always recommend? f4.5 isn't very fast, even at the 'wide' end...

mathias

OK , seeing as the 400 price range has been thrown around , then the 17-40L is an excellent replacement for the kit lens , super sharp , Im very happy with it anyway.

As regards the 70 -300 , the Sigma 70-300 DG APO is just as good as the Canon and can be had for about 200 in the shops around Dublin ( APO version ...better glass ) , even cheaper online , and has a very handy macro fuction as well ( not 1:1 , more like 1:2 but can be held further away from the subject , excellent for bugs and that sort of thing! )

That sounds good does it have IS ?

mathias

No IS , but for the price and with that macro function its a good sharp lens.

A good tripod or monopod will make up for the lack of IS.

This is the one ,

looks nice.. i have a good tripod so maybe i can get that , what about one with this good quality lens to reduce chromatic aberation and also has IS ?

probably pricey ...

magicbastarder

as thirdfox mentioned, that softness is only going to be an issue if you view or print your photos habitually at that size.

I think it might be chromatic aberration, and yes a more expensive lens would help.

Heres a link to some shots taken with the kit lens 18-55, scroll down and all the shots on the page are using the same lens

There is a lot of detail in that picture. However foliage always look less sharp in photographs because we expect to see more detail, as we see it in nature. If you increase sharpness and make the picture larger a lot more detail appears.

Most kit lenses are built to a budget so most replacement are going to be more expensive and better. The Tamron 28-75 is a good replacement standard zoom but may be a bit long at the short end. The Tamron will give excellent 19X13 prints from APS size sensors.
