50mm is very good =)

None of the lens can compete with the price vs performance

Get the STM 1 if you are shooting Video, or you are hunger for round round bookeh, get the STM 1.

Else no reason for you to get the STM version just go for the f1.8 ii

I sold my 50mm f1.8, cause its too tight for me, and take into consideration 600d is a APS-C, crop factor is 1.6x? correct me if im wrong. 50mm = 80mm. another thing is their MFD which is 0.45m

Its a fun to paly with lens, wont hurt your pocket and also low light performance very good.

Look at this i shot at night

Why would you want a 50 mm prime lens for travelling? Although sharper but your kit lens range is more ideal for all general purpose travelling.
If you want an upgrade perhaps 18-135 mm or 10-18mm.

Nah, its 880

I used this lens before, on my brother 7D. The image quality is amazing. it also has macro mode.

Sorry i miss understand the lens, im using 15-85mm not 18-135mm.Sh

yea focal length the distant you can reach, wide = shorter mm tele= larger mm

like many sifu here said, photo quality is judge mainly mainly on skill
give u a 10-18mm, a 18-135mm does your photography increase by three fold? answer is no.
Those who judge photo quality, are photo gear freak 1000% zoom check to see whether it is sharp/  chromatic aberration?/ Barrel Distortion and etc

after some shoot, people judge on good photo quality is base on.

1st and far most fisrt: Still photo, using 1/60 shutter speed on lens without IS, 1/30 on IS device

2nd: Composition, look at those people who shot at polaroid, they rely on small sensor yet they can make nice photo. and you inspire by it

3rd: Light!, that the main reason your main picture look bad, an overexpose photo is easily fix than an underexpose photo, sufficient light is your main and main reason for concern, choosing a place that has sufficient light is important. irregardless of  night or daylight scene.

4th:Post production/ aka edit. 70% of your photo is judge base on the skill and your shots 30% is on post edit. making your picture reach out to the people viewing it. make dynamic range wider to get wide colour.

Just like Sifu goldfries said, people wont care or said. ehhhh your photo noisy ( IS0 6400) nope.
people concern you capture that moment, you get the shot still, compose properlly you get a nice shot

That is photo quality

how come looks so dark one?
