The definition is actually very good when one looks beyond the camera produced jpegs.
One thing my files aren't picking up with the 28-105 is the lens description. Even trying to pick up the description from the exif in unprocessed out of camera jpegs isn't showing it yet joostdh's files do. Wonder what I need to update?
I was looking to get FA77mm ltd but with this I don't actually feel I need it now. The 77 isn't a particularly sharp lens as it is intended for portraits. I'd be surprised if the resolution of this zoom is any worse than the 77 and it is considerably cheaper (and if I need the faster aperture I've got the 50mm f1.4 to use instead.) Seems this has saved me money and no, it won't be going back!

That's a cropped shot from the lens at 105mm, so probably equivalent to around 250mm or longer.

This was one of them that on the face of it was disappointing:

There doesn't seem to be any detail in the sky at all! But with a tiny bit of over-processing I achieved this (sorry its rather OTT!)

What to make of that!
By the way, I should of said both of joostdh's photos were very good and showed great detail.

In any case, John, how do you find the other aspects of the lens, handling , and optical performance etc?
This brings me to joostdh's photos which both show the blown skies. The histogram for image 2 demonstrates this:

There's space at the left to move the curve to the left without loosing shadow detail.
It does seem to be a 'feature/quirk' of this lens.
JR has overcome it by deliberately underexposing by 1/3 stop which will help with this lens but I haven't found that necessary with other recent lenses. I've never had to do that with any of the DAs on APSC or even the other FAs and DFAs on the K-1.

If the problem reoccurs the answer might be to create a settings parameter for the lens with a lower contrast as perhaps the lens gives more contrast than others.
I've noticed some of the Ricoh example shots show the syndrome I was getting, no doubt for the same reason. So if anyone else experiences apparent overexposure with the DFA 28-105 try dialling back the in camera contrast setting before rejecting the lens.

Anyhow I'll try it again another day before I make any rash decision about it and I'll try it on my K-3 as well.
I'm not short of good quality lenses so if this one's a puck I'll either get it replaced or go without. I've got 30 days to reject it if I decide to go down that route; maybe I'll think differently tomorrow!
According to Which I have a 30-day right to reject. (Under the Consumer Rights Act you have a legal to reject goods that are unsatisfactory quality, unfit for purpose or not as described and get a full refund - as long as you do this quickly. This right is limited to 30 days from the date you buy your product. After 30 days you will not be legally entitled to a full refund if your item develops a fault, although some sellers may offer you an extended refund period. )
However SRS are saying this has to be done in 7 days. They need to get up to date with the 2015 Consumer Rights Act. So I'll have to make that decision quicker than anticipated. If it's faulty I thought I had a year or two??
