Canon 50mm Service Announcement | Focus Problem & Free Repair

August 30th 2017 3:52 PM

Everyone’s got a 50mm lens and if you’re a Canon shooter there’s a decent chance you’ve got a Canon EF 50mm F1.4 USM given its remarkable price of $350-$400. However, should you have one such take heed of this notice as Canon has issued a service announcement for specific serial numbers of this particular lens.

[REWIND: LaCie Rugged USB-C Review | Bridging The Gap Between The Computer You Have Now & Your Next]

The problem is described as follows:

“While in AF or MF mode, when the focus position is moved from the infinity end to the close-up end, the focus operation stops near the area shown in the dotted circle below.”

This is a strange development to come to light at this point given the model has been around for a long time, is so popular, that you’d figure all quirks were already addressed. Nonetheless, even if your unit hasn’t been affected yet it’s a good thing to check on, and here’s how to see if your unit qualifies.

If the first four digits from the left in the serial number on the lens body are “4918”, “5018”, “5118”, “5218”, “5318”, or “5418” then you may be affected and can send the lens into Canon for free inspection, and if a repair is required it will also be handled free of charge.

    That’s just great, a few years back I sent in my 50mm lens because of an issue with near object focusing problem, I remember thinking, what the hell happened to my lens, I’ve never dropped it or knocked it against anything. That repair cost me $90 to get sorted. So if my lens meets the serial numbers can I get my money back if I show them my receipt.

    When sigma came out with their 50mm art lens, I was very tempted to get it and ditch the Canon plastic crap, there is no way I’ll send in the canon 50mm for service again at 1/3 cost of a new lens, canon should be ashamed of themselves for the cost of service on gear

    #1 lens to replace/update with a bullet — and
    it’s not close.  How Canon does not have a sharp across the frame 50
    prime is embarrassing for a company of its size.  Forget Ferrari-like
    f/1.2L lenses that and ‘great sharpness per dollar’ lenses like the 50
    f/1.8 STM, Canon needs a workhorse all-battlefield 50 prime that offers:

    Image Stabilization

    Sharp across the frame

    Fast/modern/accurate/consistent ring USM
    Full time manual mechanical focusing

    Internal focusing — no protruding bits to take damage

    A relatively modest form factor (compared to the Sigma/Otus pickle jars)

    In short, we need an EF 50 f/1.4 IS USM just like the 24/28/35 IS lenses.

      It’s time to reflect on the fact that a simple infographic I made and have shared countless times has been posted back to me.

      Total.  Internet.  Victory.

    US Customers only….what about us poor Canadians?  Also I don’t see a serial number on my lens

      The number on my two 50mm lenses were hard to see. Take a flashlight and shine it on the gray part of the lens  shown on the picture in the article and move the lens around. It is on there just hard to see.

      Yeah, canadians are poor. Almost as poor as Europeans. Here, with an avg income of 358€/month, a 5DIV of €4129 is suddenly very pricy, esp. in the light of the D850 (or in its shadow)
