Congrats on the new Camera.... I can see the difference in your macro photos .... There's a lot of bells and whistles on these new DSLRs.
We just bought one last week... and I added a new lens.
I splurged and got a $150 macro/wide angle lens that takes some really cool pics out of the ordinary... but learning curve.
"Opteka 15mm f/4 LD UNC AL 1:1 Macro Wide Angle Full Frame Lens".... Can get 1:1 close ups and wide angle shots inside greenhouse get the whole inside of the greenhouse in the picture. It's inexpensive for what it is but all manual. Fun to mess with for sure and great for taking pics of fam and weeds close up and far back!! For the price it takes really really good pics, I'm not up to it yet.. still tossing 9 of 10...
I just purchased some tubes and closeup filters myself hoping to get really tight shots of the trichs. like I've seen from other photographers online. I also bought the macro lens kit plus a standard 18-55 lens to go along with the 18-135 it came with when ordering.
