What we meant by investing in those 2k lens are those
17-50 f2.8(not 2k lens)
100mm f2.8(1k+ only)
these are the lens that are at f2.8 constant. be it 70 or 200, 17 or 50.
For kit lens, its a starter lens with widest 3.5 to 5.6. thats the widest it can go.
Disclaimer: provided you have a decent understanding about the relation between aperture, depth of field, distance between camera and subject as well subject to background ... why do I repeat all that?
personally, i feel its good to have a long start kit lens like what i had.
So i realised my fave shooting focal length after sometimes.
Just when i started, my friends introduce me 50mm. but for me its too near the subject,
in the end, i got myself 90mm. which is more comfortable for me and also the subject if he/she's a stranger.
o.0 i was deciding wihc lens is better mah.. haha.. so i decided to go for 18-135mm.. yeah the zoom range for 55mm abit short for me.. then the 18mm abit like abit too wide.. lols.. stress.. haha..
o.0 which lens u got when u got ur dslr?
if you think 18mm is too wide, thats because you havent start shooting.
You totally feel differently when you start to shoot.
Not gonna comment anymore unless you start shooting.
Furthermore, 18mm is more than wide enough for the types of shooting mentioned. I don't understand how you know 55mm is not tele enough for your shooting- I have 2 lenses but I usually use just one, and shoot at 14mm (28mm FF equiv, which is slightly wider than 18mm on Canon cameras)- but I'm not imposing my opinion on you, the 18-135 is fine too
You need to follow my OLD mantra :
READ MORE (understand what you are trying to do first)
SHOOT more (get it into practise, and see if you understood the theory)
Post more (get feedback on what you have done and if you have put the knowledge to proper use)
