EF 50 f/1.4 USM


Just went to a shop to try 2 copies. Could not focus at all within 0.5m. But more than that it is ok. Tried with f 1.4 till all the way up.

Is it user-problem? Did I miss anything? I did not have this problem with the 500D and the 50mm 1.8 at all.

it is ok to be unable to focus at closer distances i guess. i also have this issue. but i dun think its a problem.
 

Well testing use the center point. Focus far and focus near. Esp for 50 f/1.4 use a test subject, e.g. as the sales man to be your portrait subject.

focus far is ok, although not stable.... but not focus near. Could not focus at all even it is at the edge of 2 contrast things.

wah. I think I should try to feel contented instead of getting more troubles :bsmilie:

but how near were u focusing? the min focusing distance for this lens seem to be pretty far...
 

Minimum focussing distance of the lens is 0.45m so if you were trying to focus within less than 0.5m sounds like you were inside the MFD hence that would explain the inability to focus probably

I have this lens. For its price, its fantastic. Some great photos, lightweight. Does what I would expect of it.
 

i agree. for that price it does what you'd expect of it and more actually. f/1.4...pretty sharp at wide open on a crop already.

that is what I suspect too :(.

ok, confirmed: Closest Focusing Distance(m/ft) 0.45/1.5

LOL. I am such an idiot.

oh, I tried some indoor shots, but it does not seem so great either.

Wanted to get the 85 or 135, but too long. now consider to get this instead. haha
 

got myself a 50 f1.4 just today after asking 4 shops then finally found it at AP-SL, it seems most of the shops had ran out of stocks. Just want to know how true is the rumors for 50 f1.4II usm? if it comes out in the near future, I think I will kill myself by banging my head against the wall :bsmilie:

if it comes out juz ignore it...or u can sell your 50 f/1.4. from some common sense...i dun think canon is gonna replace SO many lenses at one go. btw, the 50 f/1.4 has been performing rather excellent as compared to the other non-L primes (with the exception of the 85 f/1.8). so if canon were to change the entire prime line up, they will start with other primes first unless its been proven that in history they do change everything at one go...
 

If you look at the past history of new lens release by Canon, there are usually not more than 5 lenses per year. Here is a summary for the past 10 years:

2009-5
2008-4
2007-5
2006-3
2005-5
2004-7
2003-4
2002-4
2001-5
2000-6
 

Wah, so well researched!
So for 2010 what do you the new 4 - 5 lenses will be?
 

I have no idea but the rumor is pointing to:
[1] 70-200mm f/2.8 L Mark II HIS USM and
[2] the popular 24-70mm f/2.8 L Mark II HIS USM

Perhaps they will also include:
[3] 35mm f/1.4 L Mark II when they announce 1Ds IV as the kit lens and
[4] add IS/HIS to this good old 135mm f/2.0 L most people is waiting for.
 

This thread is for the EF 50 f/1.4 users who can share their experience with this lens. The following quote was taken from FM user reviews. A user complained:

"the AF is fragile and if you happen to bump the front of the lens you can damage the AF motor. I had a lens hood on and someone walked past brushing their arm into the hood and it damaged the AF motor. It was a $150 repair."

He isn't the only one complaining about the poor AF mechanism. Some even complained abt the AF back-focusing or front-focusing.

Personally, I feel that this lens performs well. The AF don't seem to back or front-focus even at f/1.4 or f/2.8...its always focused on the right thing. What you guys think? Any experiences to share?
I think Canon has heard enough complaints and might be coming out with MK II soon...

And an opportunity to raise the price by 50% over the current one. With the street prices of 550D, 7D and 5D2, I wonder how thin profit margin for bodies are now. Profit has to come from somewhere and I think Canon decided lenses is where they can find it. Witness the price jump for the new 100mm macro over the last one.
 

Well, if canon really user Ring type USM on 50mm F1.4, be prepared to have a bigger filter size, like 62mm or 67mm. Cos Ring USM is big.

Not necessarily. The 85/1.8 and 100/2, both with fast Ring USM, have a 58mm filter thread.
 

EF 50mm f/1.4 IS USM?

That's unlikely and would just be spoiling the market.

First it was the megapixel race, and now it's looking like having IS/VR in every lens possible.

Nikon's release of the 16-35 f4 VR AF-S is precisely the reason to start adding IS/VR to every lens possible.

IS/VR is simply another race towards ultimate low-light capability. When our sensors are preventing us from pushing more ISO, why not add IS/VR to f1.8 - f1.2 lenses?

f1.4 + 3-stops IS = :thumbsup:
