interresting, in my opinion its usuable (but makes it little lomo-like, if you not going to kill me for this word Smile)

I also think of 'lomography' when I bought this cheap old video wide converter - quite expect all the vignette. Razz

I'll give it a more serious tests today. But, the sky is so cloudy and wet today - well, lets see ...

Just curious, have you tried adjusting the distance between the converter and the lens, either by unscrewing it a bit or holding it in front of the adapter tube, or by removing the tube and holding it closer?

If you go back about 2 years in the archives in the dpreview forums, there were quite a few people testing different conversion lenses on the DP1. One of the biggest conclusions was that the distance from the lens to the converter had a significant impact on the resulting image quality.

Getting the converter further away is pretty easy... but if you find that you need to get it closer, you can either trim down the front of your adapter tube, or purchase one of the 52mm Lensmate adapter tubes and use step-down rings. Note that there were two revisions of the Lensmate adapter, and the first version was shorter. I don't believe they are marked.... So you would have to buy a used one and hope for the best. Wink

Genuine picture wasn't good either in my opinion.

I have never been really negative (no pun intended) about anyone's pictures here as beauty is in the eye of the beholder, though some, like those from Trifox, Orio, Lawrence etc. (amongst many others) are so beautiful they cry out to me.

These examples howver make ME want to cry out.. and the words are desist, stop, halt, they hurt my eyes, my aesthetic sense and my love of photography! lol

They are: Out of focus, have horrible colour, no contrast, poor framing, no saturation and.. the list would be endless.

Some experiments (such as seeing if a brick dropped on your foot from 1 metre hurts more than one dropped from two) are, as my dad said, best not attempted as the answer (if any) will only hurt! Smile

Whoa... Time to go back to bed, Doug. Wink

They are overexposed, sure.
The color & saturation suffered from the overexposure, but are easily recovered in PP.
Contrast also suffered from the overexposure, but isn't that bad...
Not every lens test shot needs to be a photo contest winner. Rolling Eyes

And as for "out of focus"... did you look at the full size? Even at the very edge, you can clearly see the veins in the leaves...


... and many samples posted here in the galleries wouldn't come close to this kind of quality for a 100% crop in the far corner:

Indeed it hurts my eyes too, but it just a test. Laughing
I shot it in JPEG, not RAW. The goal is not to produce good pictures. But, I made sure it's well focused - and it is, as Scheimpflug has shown. The original files may contain even more details - I down sized these to 1400 pix wide.

But to what end I wonder?> lol

Have a great day,

No worries Doug. Very Happy
I loved Foveon pictures produced by those who can master the SPP, but so far I found it a hit and missed operation, really. I already tried SD9, SD14, DP1 so far - but always have this mixed feelings with the camera. I wish Olympus (or somebody else, Sony perhaps) adopt Foveon, then it would be interesting. Razz

Have you tried processing the images in LR, i use LR 90-95% of the time now. I find it very intuitive and the results are great. Silkypix was also outstanding but i found the interface limited, hopefully it will mature in the near future.
