What's up with Sigma lenses?

Go to last post
Where those lenses you sent in for service "compatible" ?



Seriously, yes having spent 30 years in the industry, both camera and lenses used professionally needed to be serviced every so often and not just from mishandling.

In general lenses made for a price point fell apart if used at a professional rate.

Just like any other tool really...(Bosh Blue or Green?)

This is the cross section of a Nikon 80-200mm lens

Most of what you see (if not all ) is in glass and metal.

Amateur lenses have most of the inside sleeves and bits made with plastic.

That is part of the weight/performance/cost difference between the two types.

BTW, there is a lot happening inside those lenses , isn't it ?

No. Why do you ask?

Mostly Canon FD and Mamiya-Sekor MF lenses. A few Canon FL lenses. As I said, it's been a while.

Nearly everybody I knew did the same. Cameras yearly CLA, and lenses typically 1-2 years, depending on frequency of use.

Today people seem to use gear for several years and then sell before anything serious goes wrong. Or use longer without maintenance, and then wonder why something broke.

If you were using a Sigma lense I'd suggest that the extra e fell off and got trapped inside somehow.

Next time try a Sigma lens. They don't have the extra e and are safer.

Ha ha very funny old chap!

Shake your lenses, you'll hear the extra e's rattling around inside.

Friend drove his Corolla at 80 mph for 1700 miles and the crankshaft was done.

A cheap car is not made for that like a Lexus .

Lexus = Toyota

Lexus = luxury design, extra care, higher end components, built to last. Although even they had issues with "sticky gas pedals".

Audi and Volkswagen are by the same company, often sharing the same basic platform. Volkswagen is full of reliability issues. Audi is very good.

Just take a look here at 24-25-26.

Seat Leon is top(cheap golf)

Skoda octavia second(cheapest golf with boot)

Volkswagen golf is third.

The Only thing Audi does have interior quality. My Seat dash is a bit plasticky. A Audi has mostly nicer materials and finish. Needed for the premium brand.

They use the exact same engines and spares can be used on all cars of that share the same engine/platform. So whether you buy a Audi A3 Volkswagen Golf or Seat Leon doesn't really matter.

They all use the same mechanical parts. The A3 is ofcourse a more luxurious feeling and looking car. As materials used in the interior are different.

Driving 80mph on a decent corolla is no problem.

Trying to reach 60mph in minimum time every traffic light on the other hand.

That would kill any normal car.

Have been driving my Saab that way for the last 122k miles.

Different cars are for different things.

If you want fuel economy, don't expect sporty performance cheap.

If you want a cheap and reliable, realize it has it's limits.

If you are buying the loss leader, realize it is likely not built to last.

Which goes right back at the $190 or so plastic fantastic that OP had.

I don't know what makes me cringe more - Pedanticism or overconfidence :P

I now have had two Sigma 70-300 lenses die. The first took four years (zoom stopped working), the second was this weekend while using it (auto focus died) after a year and a half. Granted, they were inexpensive (less than $200), but heck...

I've not photographed professionally for quite a few years, but it used to be common to send lenses and cameras for cleaning, lubrication and adjustment annually, or at least every two years, depending on usage. With very light/casual (non-professional) usage, probably much longer.

Given that lenses are mechanical devices, they're probably going to wear unless lubricated and kept clean.

Low end modern lenses are built to be used and tossed, not maintained.

No offense but I never heard of Warranty Direct that claims to own all the data used to provide reliability ratings in your link. Is it well known and trusted in Europe ?

According to JD Power (an automotive industry research benchmark in the US) 3-year reliability study, the industry average in 2014 for vehicles produced in 2011 was 133 problems per 100 vehicles. Lexus was at the top of reliability with only 68 problems per 100 vehicles. Volkswagen had 158. But it looks like Audi wasn't much better with 151, so you do have a point there - they are close. Admittedly my personal experience with both brands is rather outdated :)

Automobile analogies are like driving a VW bus through the desert with no air conditioning.

That's probably true for any device where the minimum labor charge approaches the cost to replace it. But the total lack of maintenance does contribute to the high failure rate, and that was my point.

Off the subject of lenses, but I take all of that with a grain of salt.

In November I sold my 2003 VW Jetta with over 300,000 miles on it. But....it was a diesel, assembled in VWs oldest plant, with their most experienced and loyal people. That plant got the best parts, and the best plans.

When we talk about car quality, I'd look at model year, assembly plant, and model type. 2002-2005 VW diesels bring huge premiums. Gas models, look elsewhere.

i replaced it with a Ford, after careful factory research.

...for a ridiculous post. Nothing like lambasting a corporation in public because YOU weren't happy with a product. Well done! :-(

I've never had a problem with any of the various Sigma lenses I've owned.

Huh? I didn't lambaste them, didn't complain, didn't beotch. I simply asked...giving my use...if I was out of line in my expectations, and I clearly am. I get that.
