You lose 1 + 2 stops = 3 total.

If the lens shows f/4 wide open you need to add 3 stops to all apertures shown.

I really like the 2nd one. The 3D pattern on the background makes it unique.

Best thing I've seen in backgrounds for some time.

Photographers seem to think plain backgrounds are good for some reason.
They suck of amateurism.
Painters rarely use plain backgrounds nor did old school portrait photographers

Some examples.....

I still have several Schneider enlarging lenses. Good for macros.

Probably to Candisk Better than Nikdisk or Dixdisk if Dixons had bought them

Edit: Sorry I misread the post it's not Canon

I see the Samsung Schneider Kit Lens is £10 more than the Pentax equivalent

Lancashire people appreciate the superb quality of German made lenses and will gladly shell out more of their hard earned cash from working 20 hour a day in't mill for such precision engineering

USB 3.0 is so fast that you can run an external drive as a permanent drive.

I've just been looking at some old tests I did on a P4 3200 box using an adapter card.
W7 64 bit and direct USB 3 will be even faster, but 143MB/s READ is impressive.

A single SSD would do about 500MB/s but these are max figures. Actual normal use probably wouldn't be noticeable.

The 1GB 7200rpm Hitachi is even faster.

A lot of experts don't like the idea of no swapfile.

My idea of moving it to RamDisk is also a bit flaky because everything would be lost in a crash and hibernation wouldn't work.

Probably better to just move it off the SSD and onto the HDD or another small SSD to save wear on the main SSD .

The biggest boost would probably be to put your Windows swapfile on the RamDisk.

I've used a RamDisk ever since the old Sinclair QL days. Great for temporary unzipping editing odd pics for posting etc.

I use this one Free up to 4GB. I think Smeggy uses the same. I only use a 500MB one.
