hi...I've got the canon 400d with the stock lens (don't use!), the nifty fifty (f1.8) and a 70-300mm...

was thinkiong about replacing my f1.8 with the f1.4 (30mm or 50mm) - do you think it's worth the upgrade..? seems that you can buy them for about 200 quid now...

cheers

You do not say what pictures you want to take with this lenson and that is very important.

I do not know about the relative optical quality of these lenses but I am sure someone else will tell you. That could also have a big bearing on what you do.

What do you use the camera for. Do you find what you have now forces you to use too low a shutter speed. It must really depend on that answer if you need that extra speed. 1.8 to 1.4 is not that much increase. Can you turn the iso up ?

I was going to suggest that the 30 mm would give you a wider angle option over what you have now. I have always worked on the feeling that options are good but again do you need it for your photography.

Keep the 1.8 I've just bought one and it's the dogs danglies.

Unless you are going to use it a lot then £200 isn't really worth spending

cheers guys - well, I do a lot of landscape stuff, I also like to do stuff in the dark - buthr canon 400d does get a bit noisy over iso400 I find - just thought the extra f stop wpuld help - plus I love doing good bokeh shots too...
