Looking at PPA's "Plus" coverage, seems a max of $5,000 per item.

Better options?

This is the clearest demo I've found of focus shift on the 50mm 1.2.  Shows various apertures at 2', 3', 6', and 10' distances.

And...I've had a change of heart.  Good encouragement here, along with doses of reality.  Thanks.  I'm going to refuse the delivery next week.  Simply too much trouble to try and master at this point.  I will live with the lenses I have until Canon either fixes the focus shift with a new design or Sigma demonstrates they've fixed their AF inconsistency with a firmware update or whatever it takes.

Thank you, all, very much.  I will try all your suggestions to see what works for personal style, and might finally spend on FoCal too.  Time to try back-button again, I expect.

Got confused about the floating element NOT being in this lens.

Lenses / Re: Auto Focus MicroAdjust--Why the Stigma?

I don't have an issue doing afma on the canon lenses. If they are off its usually consistent and easily correctable. Its the sigmas that deserve the stigma! The amount of fiddling it takes to get a sigma zoom lens right is ridiculous. I'm camera afma probably won't work so you have to use the dock to do 4 focal length x 4 subject distance corrections. Figure 4 hours and at least a hundred trips up and down the stairs. I just can't believe they can't do a better job at the factory. Once you adjust it with the dock it may need afma on certain bodies which I can understand due to camera lens mount tolerances and such but that initial work you have to do with the dock is like starting from scratch to get the lens where it should have been to begin with.

There, I feel better now.

Sharing your feelings about the Sigma 50mm Art, which was so tantalizing yet so unreliable.  To heck with a dock if I already have a camera with AFMA functions.  That said, I was super lucky with the 35mm Art, and the Sigma 15mm fisheye has been great in all its fishiness.

For my Sigma 50mm Art, I don't think the problems were AFMA related.  I saw a post  that suggested, half-jokingly, that some of them seemed to have a random number generator on the AF chip.  Sure seemed true.

Congrats on your purchase! And now, be prepared for a lot of frustration (at least initially)  ;)

The 50L isn't built by Canon with sharpness and action in mind. Getting a good sharp shot of a young child running amok (like mine do) will likely have low keeper rates.

Focus shift is a necessary evil for 50mm lenses and the 50L is particularly troublesome. There is no surefire way to avoid it but after using the lens for a while, you could possibly predict where and how much the focus would shift but it's likely to be hit and miss.

Personally, the best solution for me has been to throw the camera in AF-Servo and take multiple shots with the 5DIII. In the alternate, the best solution is to use contrast AF in live-view whenever possible.

Enjoy the lens.


Also, I have several razor sharp lenses.  If I could have only one lens, it would have to be sharp.  But as my photography progresses, I see the beauty in light and form, radiance and color, as also being valid and pleasing.


Excellent! I've experienced this as well and consider that pixel level sharpness is overrated.

Thanks, Rahul.

Are you using back-button focus for your AI-Servo?

M, I think you have answered "YES!" to the question asked earlier by an incredulous poster, "Does anybody really think of AFMA as a stigma?"

Do tires, best in the world, need to be balanced when put on a new car, best in the world?

To think that the need for AFMA is indicative of sloppiness by the manufacturer is just wrong.

Camera bodies and lenses are made of materials that must have a certain amount of flex.  Furthermore, they are made to tolerances that permit them to be sold for hundreds or thousands of dollars rather than millions.

So being able to fine tune AF with a few pushes of buttons on a camera is a huge benefit to consumers.

Phew!

Lenses / Practical use of the ef 50mm 1.2L
« on: January 29, 2015, 06:34:18 AM »
Hi, all, tired of waiting for Sigma to release a firmware update for its 50mm 1.4 Art, and yearning for a fast fifty with a little more magic than my faithful old ef 50mm 1.4 now permanently affixed to a 60D, I bought a 50mm 1.2.  Should arrive early next week.

I'll be using it on a 5DIII for adding slightly impressionistic images to portrait series.  I've seen a lot of beautiful work done with misty backlighting and twilight backgrounds, as well as subtle motion blurs in low light.  Fifty millimeters is a very comfortable FL for me, and I also plan to use it for taking pictures of my baby daughter as she grows up.

Now I've seen many of the pros and cons of this lens, and I don't want to hear all the reasons it won't work.

Also, I have several razor sharp lenses.  If I could have only one lens, it would have to be sharp.  But as my photography progresses, I see the beauty in light and form, radiance and color, as also being valid and pleasing.

What I'm hoping for is solid advice on how to use the lens near minimum focal distance so that I can overcome focus shift.

For example, should I AF on a nose, or a cheek, or an eyebrow to try and get an eye sharp? 

I'm NOT good at manual focus unless I have a lot of time and the subject isn't moving.  Ahem.

Thanks!

Yes, fragilesi, this is true, and it is having a huge impact.

Even in my own photo-club, with all the amazing free tutorials out there, some members are grubbing for "shared" Kelby or Lynda memberships.  I mean seriously, our local library gives most of this stuff away, but they think it all should be free or cost nearly zero.

And rare is the charitable organization that acts charitably towards volunteer photographers who provide top notch images for their cause.  While people who pour cups of water for participants get invited to dinners and ceremonies, I often see photographers who have spent hours at the event, more hours processing, completely forgotten. 

Sigh.  Such is our lot in life.  Woe is me.

I wonder what the percentage of people is who actually value, appreciate, discern the difference of a wonderful shot that captures an emotional or phenomenal moment versus those who think a selfie shot with a kissy face is just as good as a Pulitzer prize winner.

Yes, this is very sad for the photographers and the profession.

However, even in my youth, when an aunt, uncle, or grandparent would give me a gift subscription (pretty much every year through my teens and even into my 20's), I might read one or two issues out of the year, including, of course, the swimsuit issue.

Waiting room at the dentist's or barber?  It would be the last thing I'd pick up, only out of desperation.

I was crazy about football, but found their coverage even of that boring. 

This says as much about the product as the profession, but there is so much coverage of sports on TV now, and of course on the web, that by the time a photo hits the print edition of SI, it is VERY OLD news.

Still, a jolt to read this and be reminded of how deep the transformation across economies since the Web caught fire.

Photography Technique / Re: Beginner Tips for Home Studio and Portraits?

Get some good books!  For full understanding of Canon speedlites, Syl Arena's Speedliter's Handbook.  For an excellent walk through many practical lighting setups, Christopher Grey's Master Lighting Guide.

Remember, with speedlites, any modifiers are going to cut down on the little bit of power you have to start with, so choose carefully and plan to work in tight.  My favorites are still white bounce umbrellas with speedlites, but B&H has a great little softbox and optional grid just for speedlites.  Impact brand, something like 24".  Avoid anything with a bracket that blocks the light, such as the Westcott Rapid Boxes.  They just kill too much light.

Get a mannequin head and place it up on a stool or something and practice, practice, practice!

Does anyone know if there is a firmware-type hack for the 60D to alow AFMA? I really wish canon didnt dumb down the 60D

I believe you put your 60D down by any wireless tablet, then enter the following into a search engine:  7-0-D

Choose a suitable retailer and order.  Update complete.   ::)

My concern is that with the dwindling of photojournalists, demand for rugged bodies and fast lenses will go down, and Canon will push more mediocre choices.

Yes, Canon still offers amazing stuff, but...

Third Party Manufacturers / Re: Sigma 24-105 f/4 DG OS Discontinued
« on: January 22, 2015, 05:42:27 AM »
Despite the old design, the ef 24-105mm f/4 is still a bread and butter lens for many, many working portrait photographers, especially when on location with small strobes.  It is also still very popular as a landscape lens for many enthusiasts, and still being praised in workshops by nature photographers.

The Canon price is fair and the lens holds up to heavy use.  And it has that cute little soft black ring around the mount.

I'm definitely not an f/4 lover, but this really works for daylight events, as well as for portrait sessions where I know I'm going to need the FL range.  And it's also a lot of fun for long exposure photography with an ND filter, as it is sharp and has that great FL range.

I'm surprised often when reading RANGEFINDER or PROFESSIONAL PHOTOGRAPHER to see an incredible image had been taken with a lens that is often dismissed in this forum.   ::)

So, no, it was not a good product choice by Sigma, but at least they didn't keep going down an unprofitable road.  Apparently they have management that knows when to admit a mistake, and the company is nimble enough to shift somewhat quickly.

I do wonder if there might have been a patent dispute involved, but that is 100% speculation.

I liked the feel of the 50A, but had AF issues.  Waiting for the long overdue firmware update to try again.

Ok, I do think we need a policy that requires reviewers to be certified and licensed in the state or province where they reside.  Furthermore, such a license should not be issued to anybody who does not have at least an MA and an inspected, state-of-the-art lab.

Facetiousness aside, we get what we pay for in reviews.

And worse, paid influencers are all over the place, even on this website, alas.

To quote Mr. Monk, "It's a jungle out there."

Thankfully, AlanF and others are sharp enough and concerned enough to spot and report poorly executed tests and reviews.
