There is no "again" if I've never been there in the first place
This was not directed at your thread, it was directed at the emotionally-charged comment that SDM was pathetic and a well-documented joke, which it is neither. It is, however, prone to failing due to the tiny electronic motor within the lens. Optically, they're amongst the best zooms you can get.

If you want quiet, fast, accurate auto focus, HSM is your only option. SDM is a pathetic joke; an unreliable joke that has been well documented.
Perhaps a little bias in your reply?

The problem with HSM is that the lens the HSM is focusing is sometimes less than stellar. I had used Sigma 50 f/1.4 and it was a disaster bokeh-wise. I'm sure Sigma makes some nice telephoto lenses though...

I've lost count of all the threads - not posts - running threads on this subject. There is a continual flowing stream of these threads started by affected users with contributions from even more affected users; not just here, but at dpreview as well.

To be fair not everyone that has bought an SDM lens has experienced a failure of sorts; in response to all the complaints there was a thread dedicated to that subject, but list of unaffected owners wasn't very long.

Like so many people before and after me, I wish my experience with SDM had been different. My position is nobody considering an SDM lens should be ignorant of these facts. Buyer beware. And that's all I have to say on this subject in this thread.

i'm just talking about the "series" in general as compared to the other. Not a particular lens.
I'm afraid it's impossible to give an educated answer to such a vague question. It's like asking which series is better, the Lexus Rh or the Mercedes CLK.

You really have to compare similar purpose or focal length lenses, and even then "which lens is better" really depends on the person because each of us have different preferences and style. There's no such thing as "this series in general is better for everyone, period" or "this lens is better for everyone, period".

You have to answer these questions (for yourself or the trheat). What is my budget? What are my priorities in sense of photography (landscape, portrait etc). Then you can look into the desired lenses you want or could use and purchase them in the coming tears.

Anything with SDM is untouchable for me - once burned my money, never again.

By that logic I could never consider a Sigma HSM lens as the only HSM lens I've ever bought had a defective motor. By contrast I've owned all 6 DA* lenses (still have five of them) and haven't had an SDM failure.

That said, I would not hesitate to buy either a lens with an SDM or HSM motor if that was the lens I felt best suited my needs (taking into account the potential risks).

Me too. I have 3 DA*'s and have had them for a while with no problems whatsoever. I have had 2 HSM's (still have 1). The one that I later sold arrived with a gritty focus motor and had to be sent back for an exchange. I ain't skeered of SDM or HSM either, though.

Be careful, that makes two non-negative SDM posts in a row. I'm pretty sure that's not allowed.

I own several DA* and DA Limited lenses (I had an FA Limited but sold it). The DA/FA Limiteds are all primes and nothing longer than 77mm, so you have that limitation. The DA* are both zooms and primes, and they are all weather sealed.

Optically, I think all of them are great. As for the SDM, I've owned them for several years now and a couple of them seem like they're slowly failing. It takes a while for the AF to get "warmed up". You can read many (m-a-n-y) more threads about SDM, so I'll stop there.

I also have the DA18-250 superzoom, which is probably the antithesis of the lenses above, yet I love using that lens as well. Whatever you buy, use it and enjoy it, and don't worry about what you don't have. They'll all take great shots given the opportunity. They'll all take crappy shots as well. You can determine which it is.

I'm almost certain your relationship with the DA*16-50 is cursed

Is #4 the one you got back that was suppose to be brand new and didn't work the first time you tried it?

I took the plunge. I will have an FA 31mm f1.8 Ltd arriving tomorrow. I hope it lives up to its reputation.
