I had one till recently. IQ wise it's outstanding. The only problem is that is focus throw is rather small especially for a lens that goes from infinity to 2:1 magnification. That really annoyed me considering it's a manual focus lens. That is a very bad design oversight of this otherwise perfect/amazing macro lens.
Not to mention at macro distances it works very well with 2x TCs too! So you can get up 4x magnification without having to buy any specialised lens like the canon MP-E which in itself is very well worth it.
Not sure what format your shooting, I use a Canon 50mm f/2.5 Tack sharp little lens but depending on what your shooting the 50mm might not be long enough
looking for a macro lens just wondered if anyone has one of these and whats your view of it ?
Laowa 100mm F2.8 2:1 Ultra Macro APO Lens
any other reccomendationd for a good macro ?
