I'm leaving for Cancun soon and wanted to see if everyone here could offer some advice/suggestion on what gear I would need for the shot I'm looking for. First my gear consist of the Olympus E-PL5, 17 1.8, 45 1.8, and 60 Macro. I'm planning on taking a lot of sunset/sunrise and panorama shot of the ocean/scenery and of my gf and myself. I've seen some really cool dramtic shot of the ocean using a polarized filter and would like to try it out. I always like landscape photography and since I'll be spending a lot of time on the beach I figure I'll dip my toes in landscape photography. I was planning on bringing my 17 1.8 as a walk around/all purpose lens. I was considering picking up a Rokinon 7.5 Fisheye for landscape, I heard Cancun beach is very pretty. Do you think it's worth buying the Rokinon for landscape or should I just take multiple shot and combined them in PS to make a panorama ? I was also thinking of picking up a polarized filter for the 17mm for the more dramatic and deep color ocean/sky shot. Can I use PS or Lightroom to create the same effect? Any other gear I should be considering? Thanks in advance for any advice/suggestion.
