Like the famous Eric Hanauer says, hate to break the budget. Most serious photographers have a macro arsenol of a 60mm and 105mm lens. Martin, you recall the opportunities I had in Utila and Coco view with my 105. Some situations are perfect for the 105 and others for the 60. Like your eagle ray shot with your 60mm. That was perfect. Having both makes you more flexible to the dive site life. I'd also say that you might be very pleased with the 12-24. I got a few good pics with that lens because of its zoom flexibility. You might want to nab a 12-24 before you get the 10.5 because it is more flexible underwater and topside than the 10.5. I just ordered a 10.5 and will have it tomorrow (Dec 2). :wink:
As a whole, a good Nikon DSLR setup might include a 60mm macro, 105mm macro, 12-24 wide angle and a 10.5. So, if it were me, here is the order I would choose in purchasing my lenses.
1. 60mm macro
2. 12-24 wideangle zoom
3. 105mm macfro
4. 10.5 FFF
I just got my 10.5 for $575 brand new with full Nikon USA warranty. So you could pick up a new 105mm macro for around $500-$550, and have $400 left over. Save a few hundred bucks more and you can have the best of both worlds with the 10.5 and the 105. Since you already have an 18-35, maybe it makes better sense to go with the 10.5 first. You may be able to use your 60mm port with extension rings to shoot the 105 (check with Aquatica) and I know you have an 8-inch dome that you should also check with aquatica to ensure it will work with a 10.5 (if you go that route).
I know this is backwards from what I recommend, but you can almost knock out two great lenses for $900...ALMOST, but not quite.
I hear James loans out his 12-24 for free. Call him and he is sure to overnight his to you for evaluation
Just Kidding!! Just kidding!
I have attached some pictures for you. One is of you, the other two are the refugees we found while looking for whale sharks.
Enjoy!
