From the unpredictability I've now seen, I'm really only concerned about the apparent asymmetry, since this might suggest that the optics haven't been assembled quite right.
That could well be the case. I tend to think that lenses have characters of their own and sometimes defects can become advantages, but that depends on whether something creative can be made out of them. If it ends up just being a defect with no advantage, then that's a rejected lens I think.

We used to shade the edges of prints in the darkroom to concentrate the viewer's attention of the centre of interest, so not all vignetting is bad.

On a real world subject very often it will only be very slight and may even help the image a little. Of course it won't help if we crop the image.

I'm not a fan of online storage. If a company goes bust sometimes very little time is allowed to reclaim any images. You might not be able to get any of them because of the huge number of other users also wanting the same thing.

Better I think to make our own arrangments.

The obvious choices are JP Service Solutions, Asahi Photo and Harrow Technical.

The first one gives 20% discount to PU Plus members.

Thinking of No.1, whatever you do, don't blink......

Great images, great location to use the technique.

That is bizarre, but someobody could fall for it.

The pellicle mirror failed because it made the viewfinder too dim. The Sony solution is to use an EVF, but although acceptable that isn't yet good enough IMHO.

I think the real problem would be keeping the relatively prominent mirror clean enough. We think we have dust problems now.......?

Sometimes when we get a card fault, the card will work in one camera but not in another identical one. So we get the images off via a card reader, or via the camera if that's all that works, and then discard that card. The images are the imprtant thing, so a new £5 card is neither here nor there.

If the cards are any particular age, the a new one may be OK. Also, don't forget to format the card in the camera every time you want to delete all the images. If you don't there is a small risk of card failure.

Hope that helps!

In Ancient Times the standard lens was often doubled up as an enlarger lens. Not ideal maybe, but they were symmetrical designs and not too shabby.

The Pentax 55mm f1.8 lenses were pretty good for this, so I hear.

I think you must have had a damaged one Algi, all those I've used have been excellent lenses.
