What was said was, it is "nearly useless" in low light situations. "low light" is incredibly vague..for starters.
1/45s, f/1.8, ISO3200...THAT is what I mean by "low light". The 1.4 can do this with ease; the 1.8 simply cannot.
Secondly, having a fast lens is NEVER "nearly useless" except in "useless" circumstances.
Yes, like the 50/1.8 is useless at 1/45s, f/1.8, ISO3200. 10% keepers is not enough for me.
Sharing your experience is appreciated and valued. I am arrogant enough though to suggest, if you feel the 1.8 is only useful in "full light" situations, you didn't explore the capabilities of the lens.
The 1.8 has the following good traits:
1. Cheap
2. Better-than-average sharpness and contrast
3. Cheap
4. f/1.8 allows much shallower DOF than an expensive f/2.8 zoom
Other than that, I think I've used that lens enough to know that there are better options out there. We're all wooed by items 1 and 3; but there is a difference between cheap and inexpensive. I think the 50/1.8 cuts too many corners, and could be made MUCH better by the addition of a decent, modern AF system like USM.
Oh wait, that lens already exists: it's the 50/1.4.
I still contend that the 50/1.4 would be considered an absolute steal at $315ish new, if the 50/1.8 did not exist. We make excuses for the 1.8 because it's cheap.
Again, I'm not saying the lens didn't fail to meet YOUR needs, but what I'm getting an attitude about...is that to me...you and Edge are taking those valid experiences and concluding the lens is practically worthless. That is simply hyperbole and flat out wrong. In fact, the 1.8 is an incredible value. No one is denying its limitations.
It's not worthless, given the right set of circumstances. And there's the rub...why be limited by circumstance? In the 50/1.4, you get a lens that can do everything the 50/1.8 can do, do it better, and do a few other things that the 1.8 can't do.
We're making excuses for a cheap lens, when an inexpensive choice is available.
In very low light, the 1.8 is useless unless you're willing to use MF. Perhaps you wont shoot in very low light too often; but why handicap yourself with a lens that cannot be used at all, when another choice is available for not much more? The 1.8 is false economy, in my opinion.
"Questionable lens"...incredibly subjective and relative. Where does this stop? Maybe we should start comparing the build(!), color and contrast characteristics of the Canon 50mm to the Zeiss ...so everyone should get the zeiss?
Dude, you are totally missing the point, despite having it repeated to you over and over. If Zeiss quality is necessary for you, then you get the Zeiss. If 50/1.2L quality is necessary for you, you get the 50/1.2L.
What I'M saying is that the 50/1.8 is a decent lens, given the right circumstances. And those circumstances are the following: you absolutely cannot afford the vastly superior 1.4.
Can we agree...all lenses have their strengths and weaknesses?
Yup. The 400/2.8L is a brilliant telephoto prime, but is heavy and expensive. The Canon TS lenses are terrific for architecture photography, but are MF only.
The 50/1.8 is crap in low light, but produces better-than-average (better than kit for sure) IQ in good light.
For the OP, he made zero mention of low light photography. He *did* make mention of price / value.
Exactly. And the 1.8, while cheap, is poor value.
He *did* mention portraits. He also didn't express a deep knowledge or experience with photography. So...maybe it makes more sense for him to explore using fast glass on a $75, no risk investment versus over $300?
Naaah...nothing holds its value as well as well-cared for glass...especially good quality glass like the 50/1.4 Decide you want to try basket-weaving after a year? Sell the 1.4 on FM.com and make back 95% of your money.
I prefer to make suggestions based on the OP's stated needs and priorities versus guessing what they might or might not need in the future
I should point out that even if the OP only ever shoots in studio lighting, the 1.4 is STILL better.
...especially when we're talking about a lens he probably paid $75 for..and can resell at zero loss.
How do you square this with your previous statement that
..maybe it makes more sense for him to explore using fast glass on a $75, no risk investment versus over $300??
That you and Edge pointed out some of the limitations of the lens...that's great, but you guys, especially Edge, denied the 1.8 the value it *does* have for the uses the OP needs. That's unfair, inaccurate and doesn't serve the OP imo.
Never, ever did I deny this. The 1.8 may be wonderful for portraits on a 1.6x crop body (it isn't, in my opinion, better than the 1.4 in this regard...). But again, why be constrained?
As I said before, buy once, buy right.
I've switched back to Nikon, but I know both lens very well. I have been in what I would call "low light" circumstances and the 1.8 saved the freakin' day! After many years in this business, I'm just not concerned about the red or gold ring around my lens. I still have MF Nikkors that you can get for a song...sung badly... and that kick booty! This digital age of photography has launched a MASSIVE "gearhead" community. Not my cup o' tea.
Good for you. I've got a Fujinon 55/1.8 M42-mount prime on my Fujica ST-801 that is absolutely superb.
This is not about a red ring. I didn't tell the OP to get a 50/1.2L no matter what because everything else is useless. I told the OP to buy smart; that the 1.8 would get old fast; that the 1.4 is a better investment.
