That's come down a lot. Not too bad.

I would say that lens looks like a duffer. I would expect much better sharpness. Selection here.

Given the price I think the u is appropriate.

Good examples. An adapted 50mm is a useful option either if you haven't got anything around 300mm or where you couldn't use a 300mm. Certainly good enough for web display or small prints. A comparison between an adapted lens and the 06telephoto would be interesting.

I'm a simple, uncomplicated soul. I just interpret May as the fifth month of the Gregorian calendar. Happily the may tree is in bloom. So I may photograph the may in May. That should have it covered.

I'd really be looking to find a way to try before you buy.

The 50-135 has superb image quality and F2.8 is a big advantage over f4. However, autofocus is slow. Coming from Canon you might be surprised at how inadequate it is. Af motor failure is common with this lens but the silver lining is that I have heard reports that the replacement motors are much faster. So if you can find a lens with the AF replaced with a recent motor, or even a broken one and have it fixed that could be a solution,

The DA*300 is an excellent lens. Af might be a bit slower than its rivals but the greater working distance means it's much less of an issue. It would be find for autosports.

So great image quality. But to be honest if I were predominantly interested in action then I would be looking at another brand.

So do I

The full size Lees are large. Using them on small lenses such as yours means that you use very little of the graduation. I think the Lees are much better suited to larger lenses. There is a smaller Lee system which suits the smaller lenses down to a certain point. I enquired at Teamwork and they were convinced that they would cause vignetting on the DA15mm. The DA15 has a built in hood and you have to put a spacer in order to attach the filter holder. On the other hand I heard a report somewhere else of someone successfully using Cokin A's with the DA15.

You could do worse than start off with Cokin A's, they are cheap as chips.

Well they refunded me the whole year's pro subscription, which is pretty generous.

You can restrict who sees the content. There are a number of options including private so only you can access it.

If anyone wants to downgrade they will be refunded the unexpired portion of your Pro membership so you don't lose out. I think Yahoo have acted correctly in doing that. Then you just delete your account.
