what has been your most "disappointing" lens?

so you get really pumped about you new (or used) lens and you take your first fell photos and pow it just doesn't live up to the hype.
what is your number 1 disappointing lens? and why? could be one reason or several

I'll start. for me it's the FA 50 1.4. I heard so many great things about it... and it's a good lens but the sharpness wide open is a downer

what about you?

The DA* 16-50mm. Due to it failing a few days before a major job, multiple times, I now own three of them. All of them, "less than stellar". For the price, they are hugely disappointing in build quality. (and I take VERY good care of my equipment with regard to bumps, storage, etc..)
The zoom ring jams frequently. One of them has been repaired five times for the same issue. Another three times and the third, only once so far.
I have never owned such crap in all my life, but the image quality is decent.
Having to deal wth CRIS and then Precision for products like this has been a complete nightmare.

Other than that, I agree that the 50mm 1.4 had the worst image quality of any of my lenses.

I was unhappy with decentering problems of Samyang 14mm. But once you get a good copy, it is amazing
Flektogon 35mm is not super sharp wide open, but I still find it acceptable, especially at that price point

For me it is the used Sigma 400mm AF f5.6. It purple and green fringes are really bad. I can fix them in post but it's still annoying to have to do that.

This one:
Sigma 400mm F5.6 (AF) Lens Reviews - Sigma Lenses - Pentax Lens Review Database

And I've tried a hood, didn't help. I tried above f8 and it didn't help either. So, I may be unloading it on ebay and look for something in a Tak.

SMC-A 70-210. My first 'big' zoom. Before that I had only ever known the efficiency and portability of a 50mm. I was excited to 'get in closer', but was immediately put off by the bulk of the lens. Gone was the near effortless balance of MX+50/1.7 to be replaced with the unwieldiness of a can of beer taped to a bar of soap. Yes, the glass was sharp, but rarely did I notice that fact long enough before I found myself bumping that big lens into yet another corner or lamp post when I turned my head.
My copy also had horrible zoom creep, which only amplified my dissatisfaction.

That lens alone put me off both zooms and big glass, (which are often, though certainly not always, one in the same). Th biggest glass I currently own that I shoot with any frequency is the Vivitar Series 1 90/2.5 Macro, and that is always on a tripod.
The largest lens I take out as a walk around is perhaps the SMC-M 150/3.5 or the Super Tak 85/1.9.

Hard to tell. I go through stages. At first, I am disappointed with a lens, followed by learning a lens' strengths and weaknesses. For me, my big disappointment is the FA 50 1.7. I've had two copies. For some reason I like the F 50 1.7 color rendering so much better.

DA15 Ltd. Grossly over-rated. The DA16-45 at 16mm is just as good and at f4 much better.

The Pentax DA-L 18-55mm. It's kinda soft. It's very slow. The 16mp Sony sensor seems to out resolve it.

Phoenix/Samyang 500mm 1:8 Mirror. Never got even one single satisfying photo out of this lens. Regardless if I use PDAF, CDAF or MF, it always falls behind a crop of my bread-and-butter 55-300.

I had another variant for a short stint - the 400mm F5.6 APO that lens was quite nice but i sold it due to the 150-500 versatility.

My most disappointing lens would have to be the DA* 16-50. SDM failed recently and I have been reluctant to spend the money on getting it replaced/repaired. I am teetering on buying the K-1 24-70 F2.8 Combo

I also felt that it wasn't quite hitting the mark on the sharpness side of things.

DA 55-300
I've had 2, a metal mount one and then the WR HD one. Neither gave me photos I was happy with, on my K5 or K3. I got the first to replace a Tamron 70-300 that I dropped, and I actually found the Pentax slower to focus and not nearly as sharp at the long end. I sold this copy to get the WR one, which seemed no better. Almost everyone else raves about this lens, so it must just be the way I used them! I now have a Tamron 70-200 f2.8 and a DA 60-250 which I am very happy with.

My bigger disappointments have been buying lenses and then not reaslly using them as much as I thought I would. But then the more lenses you own the use will generally spread out more.
