i've just gotten a book on canon EF lens work and after looking at the lens selection, i think i would like something for wide shots in my lens collection. i am a student and i am trying to get the best bang for buck and thus this question.
how good is the 18mm end of this lens at f3.5?
i hope to do alittle landscape photography with this.. the book had a couple nice building pictures too, i was wondering if this lens is enough or should i save a little more for something with a larger aperture.
my worry is the f3.5 is too small for dim lit scenes like if i were taking the singapore sky line at night, a sunset or shooting indoors. its either i get this 18-55 or i put in alittle more dough for a 24/28-85/105/135 at f3.5 or f4.
btw, is there a non IS 28-135 f3.5-5.6?
You seem to be worrying about buying a lot of stuff, which is why I originally suggested in staying with the S3. However, if you really want to jump into DSLR, no one can stop you except yourself (and your finances).
You must learn/realise that f/3.5 is not an aperture most people would use to shoot a landscape/scenery shot. Most would stop down to f/8, if not f/11. Larger aperture lenses won't make your scenery/architecture/landscape shots better per say, because you aren't going to be using the large apertures for scenery, geddit? However, large aperture lenses (generally speaking) have better optics, but they are not cheap.
Now isn't f/8 or f/11 even smaller than f/3.5 you ask? This is where tripods come in. If you're gonna be shooting the Singapore sky line at night, common sense would tell you to sit your camera on a tripod, not boost the ISO. Maybe this is what you haven't been doing, thus complaining about noise. I wouldn't know; only you would. I'm just speculating.
18mm is wide enough. It is actually very wide to begin with, and suitable for most landscape shots. What you must learn is that wide angle photography is not about fitting everything into your frame. Composition with a wide angle requires much skill, and it's something that I admittedly am not that good at.
At your stage, I wouldn't even recommend other lenses, because you already mentioned you're on a limited budget and you want to start on a DSLR system. I will reiterate points about a DSLR system that I have already mentioned in your other thread, just so you know the magnitude of your decision.
1) It's pricey. You are looking at putting down a thousand at least, if not more, inclusive of memory cards, bags, dry cabinet, accessories, filters, blower etc.
2) It's bulky. You may use it, and after awhile complain about the weight.
3) Maintanence is an issue. Either you bring it everywhere you go, or store it in a dry cabinet. Leavning it out in the open, untouched, is a recipe for fungus, mould, and a whole host of other unpleasantries. And even if you're using it all the time, cleaning needs to be done once in a while, and that can take up a fair bit of time, cleaning each lens, wiping your body down, and possibly cleaning your sensor.
4) DSLR is a system; it's an incessant upgrading process, that you are going to spend, in the future, hundreds and thousands of dollars on, if you decide to embark. 'Til now I know of no one who has bought one lens and a body and says "Oh, I'm fine. I'll stop here." I really haven't. You're already looking for better glass before you've even started. That says a lot about your upgrading path
