Canon EF 50mm 1.4 USM OR Sigma 50mm 1.4 EX DG HSM


Strange that so many here and other forums are bitchin' about the canon 50mm f/1.4 lens.

I remember during the film days, and even till today, the 50mm f/1.4 is the standard golden baby to be featured together with Canon's mid range and top of the range camera bodies.

I somehow feel back 20-30 years' ago, people really take pictures and enjoy the finer art of photography. With digital, the danger is that we talk photography with our mouths more often than shoot with our eyes.

I also remember the Canon f/1.8 was all praise as the cheap yet sharp lens when I was shooting lots of films in the past. It's favoured by amateurs especially, and even pros used it. The f/1.4 was even better if you could stretch your budget.

Today, we hear amateurs and photography "whiners" who complain and complain, Wooooh, my f/1.8 lens not sharp enough. The f/1.4 wide open too soft. (Do they understand about lenses at all???) These were seldom heard of in the past. Could it be that people today love to study a picture like a microscope and lose the joy of photography? Many stunning pictures were produced in the past with these lenses.

Today, we see L, L, L lenses. All we ever hear is, Buy buy, buy those L lenses. If want a 50mm, go for the 50 f/1.2 if possible. But with what kind of pictures can these photographers show for?

Now, the "in" thing for forummers to do is to whine how bad their Canon 50mm is compared to the Sigma 50mm.

But have you guys considered the real experience of having front and back focusing issues? Sure, some say you can calibrate it. But AFAIK, the QC for Sigma is not good. That's why you get all the various reviews which is so confusing. Why buy a Sigma and then leave it to chance on whether you get a good copy? You want to have headaches and leave the focusing to chance when you should be concentrating on taking pictures?

And have you also considered that the Sigma is heavier, bulkier, and of course, more expensive? With the 50 f/1.8 or 1/4, it's a no brainer. You hardly feel it or realize it's there in your camera bag.

As for bokeh.... well it may be true that the Sigma is "smoother" (and that's if you zoom in close to study it like a pixel scientist), but with all the uncertainties and problems above, is that really a plus point? I don't know of anyone good in photography who judges a picture by its bokeh! That'll be a joke. It's all these internet camera and lens reviews that I find are guilty in misleading us into getting our priorities wrong in photography.

In the time that some common forummers here keep debating whether to get the Sigma or Canon 50mm, or justifying their lenses, lots of photo opportunities are wasted and slipped by. Think about it.

For all you know, those guys in fourms who said they loved their Sigma may not even be true photographers but lens collectors. Just cos its bokeh is good etc doesn't mean the end. They may not have shot enough to encounter the focusing problems that are so prevalent in the Sigma lens. And who knows, maybe by the time you read those outdated reviews, those guys probably would have sold off their Sigma!

So it's really your call. Take the chance and be really happy with your Sigma, or end up with all the bad focusing issues and uncertainties and a heavier bulkier lens which hardly improves your photography by leaps and bounds compared to using Canon's 50mm.

For sure, there are pros and cons in both brands. But whenever I hear one sentence advice "Get the Sigma over Canon", I feel skeptical.

Just feel like rambling today... :) Food for thot....
 

IMHO, the differences are very minute, but all of them render differently.

I totally agree.

The great thing about this Canon is that it is cheaper than the Sigma, which is unusual.
 

how abt comparing canon 85m f.18 to sigma 8s f1.4?
 

Thanks for all the responses/ votes. I'm currently using the canon 50mm 1.8 and not really happy with the sharpness. Images too blurred (probably it doesn't have IS).

Was hoping the canon 50mm 1.4 would be better but it seems (based on the responses) it is the case.

Sigma it is for me. Does the sigma 50mm 1.4 ex dg hsm has IS?

Negative, Sigma 50mm f/1.4 does not have image stabilizer/vibration reduction.

I am also in a similar situation... currently on Canon EF 50F1.8II and shoot quite alot of portraits (especially kids) and found that although the shots are good... felt its not sharp enough... as I am a newbie to photography, some friends have advised me to change to a F/1.4 for better results... any comments?

If you find the 50mm f/1.8 'not sharp' enough, it could be focusing issue or end-user issue. At f/1.4, the depth of field is extremely narrow; it is extremely easy to go OOF.

I have the same problem. I'm using the canon 50mm 1.8 and find the sharpness really bad. 1.2 is sssooo expensive and that's why I was considering sigma as a contender. I was figuring that the canon 50 mm 1.8 wouldn't have that much of a difference to the 1.4. That's why I started the question.

Can we now discuss as to the sharpness of the two lenses?

OT
 

yep, where degradation of sharpness is all you have to worry about, and can be decently resolved during PP. Where as when you get a front/back focused shot, I don't know if you can do anything about it to make it look decent enough...

The EF 50mm f/1.4 has a dreamy look about it when open to f/1.4. I think when one pulls out these primes, one is hoping to achieve some shallow DOF dreamy look. So, the so-called 'lack of sharpness' (it's still sharp enough for me) actually adds to the feel and general effect.

However, the Sigma's focus shifts as you change f/stops. I won't call it a front/back focusing issue because this problem only causes back focusing as you stop down.

When I shoot, I want to worry about the composition and the general feel of the photos. It is really fine if it is slightly less sharp. So, I vote Canon.

So what if the Sigma is sharper, better built, etc... The focus shift is a problem I don't want to worry about. When the subject moves a little forward and exits the DOF (since the DOF moves back as you steps down), then the shot is lost.
 

The advice here seems to have changed from "Go for the Sigma!" initially to now "Wait a minute..." :o

I have been reading quite a bit about this Sigma 50mm lens in the past few days ever since it was brought to my attention recently.

Seems like a "strange" lens in the sense that it has plus points, but yet on the other hand, you get other problems which cannot be ignored entirely.

I'm not sure if the supporters here and in the other reviews I read are painting a positively accurate picture about the Sigma.

I see many of them concentrating too much on the better "bokeh" of the Sigma. But little attention is paid to the dodgy focusing issues.

Front /back focusing of the Sigma seems to the big question of this lens. Some claimed they had it, and was so disappointed with the lens that they didn't even want to touch it any more. That's because the problem is not easily resolved by just having the lens calibrated. The Sigma lens can only focus properly at a certain distance. After that limit, it seems to go "myopic"! Honestly that's the first time I am hearing this!! Weird. I certainly don't want to be caught in this situation. It's so stressful.

Strangely, others don't seem to experience this at all. In the worst case scenario, they had to only recalibrate their lens at Sigma or manually dial in the correction in their cameras (if they can).

I think it boils down to poor Sigma QC perhaps? It's a risk one is taking. I'm not fazed by this lens now....

I also read that at smaller apertures, the Sigma's image quality is actually worse than Canon or Nikon's 50mm lenses. Another weird phenomenon. So *cross fingers* unless you a lucky to get a good copy of the lens, you should be shooting at wide apertures most of the time. After f/2 onwards, there's nothing much different about the Sigma from Canon. After f/5.6, the Sigma actually becomes worse!!

And for the bokeh fanatics, do you notice the reviews always analyzed and compared the Canon and Sigma by blowing up the images and studying them closely? That doesn't sound practical. I think they are pixel-peepers! Seriously, who judges the worth of an image this way?!

Having said that, I don't know why the 50mm is such a difficult lens to design. Obviously, to me, the Sigma has its own serious focusing problems that cannot be ignored. For the Canon, there is the "soft look" at big apertures. I don't quite like it myself. And the blur looks harsh and artificial. Sometimes, you get very strong CA also. I read the extremely expensive (not worth it to me) 50 f/1.2 used to have the focusing issues also in the past. Not sure if it has been resolved...

So which is the best 50mm lens out there? I don't know....!! :confused:

Think you answered yourself if f5.6 performance of the Sigma is essential or not. Anyway my 3 big aperture lenses, don't really use them stopped down past ard 2.8. :)
 

My AF-S 24/1.4 also somewhat goes myopic at longer distances. So does the Sigma 30/1.4. (but of coz the AF-S is much more reliable). Yep they are "bad lenses"..... But many still make good money with them, hundreds of thousands of frames shot here already. :) I actually got a shoot which I think some CSers were surprised I could use such a lousy lens as the Sigma for a paid shoot and its definitely not a lowly paid shoot. :confused: So the thinking varies I guess.

Impt thing is just buy what you really need for the +ve points of a certain FL. There are definitely bad copies of any brand's lenses out there, there are also people who find it difficult to do big apertures and compose a picture correctly with nice bokeh to complement the storytelling.
 

How bad is the Sigma from f/5.6 onwards?

For me, I will choose the Canon 50mm f/1.4 hands down. Mine is 8 years old (since my Canon film body days till DSLR now!) and I've never encountered any issues with it. No motor problems also. It also gives me the ease of mind that if I use new Canon DSLRs in the future, it still works. Maybe there are good and bad copies of Canon lenses also?

I'm not sure about brands like Sigmas.... Do you guys have to constantly do firmware upgrades whenever you use the old lens on a new camera body? Got to pay?

If the Sigma lens image quality starts to degrade at a relatively big aperture like f/5.6, then it's not for me. Cos I need that reliability to rely on the lens at any situation. I've used my Canon 50mm at apertures like f/16. You'll never know when the situation arises.

When I read that some people have focusing problems with the Sigma at 3 meters or more, I was like.. What? And for some, this problem cannot even be resolved after calibration from Sigma. What's the point? I don't want to buy a car that is promised a very smooth ride from 0 to say 40 km/h. After that, the ride gets rough!

I suppose to each his own. For those still in a big dilemma between the Sigma and Canon 50mm, think carefully the pros and cons of each lens. Most of the time, I find the issues with the Canon 50mm are overhyped. Be careful whether you are seeking opinion from passionate photographers or pixel-peepers/lens collectors!

There is a huge difference between one who shoots for money and one who shoots for fun. I shoot for fun and very often I am armed with only one lens on my camera and it has to be do everything. My 50f1.4 is sharp from f1.4 to f11 and that's all I need on my 5D. It shoots better landscape photos than many L lenses at that focal length. The fact is that there are more fun shooters than paid shooters, most of us fun guys cannot afford expensive lenses just to shoot from f1.4 to f2.8.

Err....don't think so.... :dunno: Maybe it makes a difference to others and they do print really big like more than 18x12.

http://www.the-digital-picture.com/...p=115&CameraComp=453&SampleComp=0&FLI=0&API=7

From what I see, just choose a good copy and that's it. I don't know why others have so many problems though. There are so many working Sigmas around.

It's really a heng/sway thing :dunno:

I bought my Sigma 30mm f/1.4 (which also has a wide-spread front-back focusing issue) and never had any problems with it so far. Did a focus chart test on it and it turned out tack sharp.
 

How bad is the Sigma from f/5.6 onwards?

Not too bad (see above), I read a review comparing the Sigma and Canon 1.4 and 1.2L at various apertures with full frame 100% pictures and its pretty useful, see if i can find it again. Actually there are AF issues with the Canon as well, as for the frequency vs Sigma 50/1.4 I am not so sure. But for sure the Sigma 30/1.4 is a much more notorious lens than the Sigma 50/1.5 in this regard.

Actually any big aperture glass needs some work and concentration to do at f1.0-f2 and it happens to even wide angles, tried all the systems L, C, N etc.. Some better than others of course. Overall still can work....I don't know how to put it, coz for me it just NEEDs to work, by hook or by crook. :bsmilie: I can only say what can what and work cannot work in a real setting, its only during a real setting / shoot that I can say that out like during some weddings in which there are supposed to be some CSer (like this coming Jan 8....i think the groom warned me got a big group). Does not mean your "canon sure will AF confirm and my Sigma cannot" here on paper.

But no matter what, just concentrate on the glass lah....bodies come and go, if you have been shooting for long.

My 50f1.4 is a manual focus lens as I don't trust AF lenses.
 

Sigma or Canon... get whatever makes you happy. I have a Canon 50mm f1.8 that I been using for the past 5-6 years, love the lens, no problem at all. Recently bought the Sigma f1.4 had it calibrated to my 5D and loving it as well. I am a Canon guy and the 50mm Sigma is the only 3rd party lens I have. The most important thing is go out and shoot more. At the end of the day you must like your photos.:)
 

Choice is sigma 50mm with D700 and canon 50mm with 5DMk2 as they produce ideal IQ.
 

Juz curious:

Will Sigma Singapore do the calibration for free if the lens is already out of warranty or not bought locally?

And will the calibration affect the focusing ability of other Canon lenses on the camera body?

There is a $80 charge if you do not have valid existing warranty.

Not exactly sure, but I'm inclined to think that they calibrate the lens to your camera body, not calibrate your camera body to the lens.
 

hi just would like to ask, how long would calibration take?
