<p>Hello friends, I'm trying to decide on my next lens and could use some thoughts here. I've used both lenses and think both would do nicely for my needs. So, here are the facts just in case anyone thinks "what about upgrading this instead...":<br> Shoot events, weddings, parties, portraits, etc. Also shoot the occasional golf course.<br> Currently shoot with a D4 and a D600, both bodies are perfect for my needs. Sometimes I look at the 810, but hate the idea of 36MP photos and the havoc it could wreak on my workflow/hard drives.<br> I'm good on flashes, with a 700, 900 and 910.<br> No need for software/hardware, etc.<br> Currently own 24-70, 70-200, 50 1.4 and 85 1.4. Never needed anything wider than 24mm.</p> <p>The 105 comes in handy for detail pics at weddings and I've used it for portraits but really I'm better off with the 85mm there. I definitely use the lens when I need it, but unless I'm doing a wedding (about 5-10 of these per year) I don't really have the need outside of that.<br> The 16mm fisheye is one that I recently used for the first time and loved the results. Great for dance floor pics and got some great automobile engagement shoots using it. Again, this is another one of those lenses that wouldn't get a lot of use, as it, like the 105, is pretty specialized.<br> I'm an NPS member, so I can get these on consignment but since that is limited and sometimes they may not be available it would seem better for me to own. They are around the same price so that's not really a factor.<br> I believe that's everything, any suggestions are greatly appreciated. Sorry for the lengthy post!</p>
