Thanks Alan, I'll investigate that. My flash knowledge is still stuck in the Sunpack Autozoom era but I do have a Samsung badged 540 so will investigate. Having read the sych speed is 1/180 or 1/200 it sounds that must be only half the story. I'm quite at home with the old Sunpacks but worry the voltage is too high for DSLRs and the 540 seems to have too many settings to remember for casual use!

PDCU ? Isn't that written in 8 bit basic? It's just too slow to make it a serious everyday tool and lacks many of the options available in other programs.

Out of interest, in PDCU, with auto correct on it does sort out the vignette, with it turned off it returns.



Saved the PDCU conversion as a tif, modified in Elements and border/text added in Irfanview!

Still £999 at Bristol Cameras if you hurry.

I'm curious about the technicalities of this shot. I've looked at the exif and note it was taken at 1/320". The K-1 only sychs flash down to 1/200". How do you use fill in flash at a faster shutter speed than the camera is designed to cope with? (Great photo by the way!)

The camera is supposed to correct things like that with its jpegs from own brand lenses used within their limitations, eg, not for an APSC lens used at FF, and barrel/pincushion distortion if that option is tuned on (that isn't presently.) This led me to wonder, what is the in camera jpeg like to answer your question.

What do you think?


In camera jpeg reduced to 1000 pix for the forum.

The previous upload was from the dng file converted in PS Elements 11. That won't be aware of this lens.

I don't reckon the vignetting is so pronounced in this camera processed jpeg, however I like having it in this particular image as it adds a sort of timeless quality to it.
I did experiment trying to remove it from the dng conversion but couldn't get an even result. Maybe a newer PS or Lightroom may be more refined and do a better job.... or use the in camera jpeg if it intrudes.

Update:
Tried developing the dng in camera and that does exhibit the vignetting.

Thanks for sharing David. So you didn't use any of the old costumes to recreate an original Victorian/Edwardian scene? However the dog looks pretty timeless! One could pay more than the entrance fee just for that facility and the photos are yours, not taken by someone else.
You're more than welcome to add some further shots of the museum if you wish.

Something different with the lens late this afternoon


Autumn Harvest

The vignetting seems inherent in the lens at 105mm wide open (f5.6)

The K-1 may be WR but I'm not!
Thanks. Re #5, I'd have expected to HDR that in the past but so much can be retrieved from the shadows I can recover the hidden detail in PS Elements. Simply loving the K-1, it really is the camera I've been waiting 20 years for and getting colour slide type results from digital.

Yes, I'd certainly recommend it. Much of it is outdoors, or one needs to move outside between the buildings so not good for a rainy day though. Mind it's in the dry side of the Pennines so that's only rarely a problem!

I've no idea. Certainly wasn't aware of that when I took the photo. It has to be a ghost! There was a Nikon owner who I kept running into but doubt it was he.

If you look at #7 there's a black and white figure in the shadows on the left. Mysterious.
