Thanks for your sharing.
BTW I need a general purpose macro lens.As much thing i can shot as better. I would like to try flora, insert and potrait also.and I never try macro lens before. I was now use 50mm f1.8 plus extension tube 25mm. The forcusing was very limited due to forcusing range is very narrow. My burget is limited, so i only got one chance to purchase. Once I buy I will try to fully utilize it and no burget to get another one. So must consider throughly.
Please share your expirence !!!
