My 1st Prime: 85 1.8G
Just playing with the shallow depth of field. I can see why people use a tripod with their macro lens. It was really hard to keep a steady hand. Thank goodness for digital, it was a 1:1 delete ratio for me. Comments/recommendations always welcomed.
Welcome to the joys and frustrations of narrow depth of field photography, and a good start, at first it is always surprising how small the depth of field is especially when you get too close, and an on line depth of field calculator is a really handy tool. I started with the 50mm 1.4D and now find the 85mm 1.4 easier to use.
Apart from flowers it is useful in portrait photography, and I think helps people to think more creatively, although you can spend hours trying to get a good result.
One technique I use is to capture some colourful flowers in the background which makes the blur look more interesting. Also try f2.8 and alter subject distance, to increase DOF.
If you get a chance try out the 85 1.4's the D version gives a very similar blur to the Canon 1.2L looking at the photo-zone tests. (those blurry corners are there for a good reason.) it becomes sharp even in the corners at landscape apertures, although it is always sharper in the centre.
