It focuses fine and the quality is fine. There's no apparent difference in focusing speed between the 55-300 on its own and in combination with the converter. Quality seems excellent, and may well be even better with the DA* lenses.

Not sure what you mean geordie01, there are no missing posts, do you mean the green highlighting has disappeared? Did you mark some posts as helpful?

And finally today I managed to fit in a trip to Martin Mere!

If you'd like to see how it went, here's a link to my blog on ePHOTOzine:

I like the images and I like the one-a-day idea. Perhaps more of us could try that.

Very good images, I for one would love to see some more.

Yes it is.

You use normal film but the device splits the image into two stereo pairs that are cut and mounted appropriately. It's very effective, but of course requires the viewer so it makes viewing a cumbersome and solitary pursuit.

eBay might find you a collector who is interested and it might be worth thinking of putting an auction up.

The SDM problem was really on early batches of the 16-50mm and 50-135mm lenses, but it was solved a long time ago. These things persist on the internet for ever.

There will always be some failures, but that applies to everything man made.

I have a theory that it changes the dynamic of an image in subtle ways. Conventional thinking is that in the west we read left to right so we scan images left to right. That would imply that in some areas we should reverse that thinking for best effect.

I'm not sure if that's right or wrong, but if it's right then using the reverse direction might well increase the dynamic of a shot, giving us more of a sense of tension. That's why I prefer the second image, rightly or wrongly.

Don't worry Stan, soon we'll have Flucard brain implants and record what we see directly...no need for cameras then.
