Well, I've come full circle now
I went with the Tamron 28-75mm f2.8 and after a while found I needed the Silent Focusing Motor and swapped it out for a Sigma 24-70mm f2.8 HSM.
I have used this on and off for a bit but I do now miss the wide end as I sold my DA14 last year.
Now the K-1 is all released, and the cute D-FA 28-105mm looking great, I am looking to move on my Sigma 24-70mm f2.8 HSM in favor of a DA*16-50mm or DA16-85mm for the short term.
One question, has anyone with a DA16-85 used 77mm filters on it via a step down ring, with and without the hood?
I ask as mentioned earlier, I already have a 77mm CPL and 10-Stop filter which I would like to use on either of these lenses, the DA* already being 77mm is a bonus, but the DA16-85 being 72mm.
I have an upcoming trip to the UK Lake District, and would like to have a WR lens to take with me as a more lightweight kit over the Sigma 24-70mm HSM, 85mm HSM etc.
