I am a landscape, wildlife (elk, moose etc), and astro guy. I usually take a few trips to the mountains every year and kind of want to round of what I like doing.
The 18-55 is great, it gets me decent wide angle, but lacks some on any animal that is further than 30 yards away. It's also just so-so for astro.
I am debating on the 16mm 1.4 - this could cover astro (Though some say it's not very great). I also hear the 16mm required some effort to gain focus at infinity. I am no professional, but would welcome a good upgrade from the 18-55 2.8. The 16mm would also probably be my go-to for hiking and getting those vista and flower pics.
Also debating getting the samyang 12mm WITH the xf 55-200. This would cover astro (better so I hear than the 16mm1.4). However I don't like the fact I would have to be going manual when I want my wide angle and flower shots, so there lies that downfall. The 55-200 - I know most people say it's not good for wild life, but I mean it's gotta give me more range than my 18-55 at the moment. Normally in the mountains, wildlife is around 30-60 yards away.
I know the 100-400 is obviously what I want for wildlife, but that's just out of the question for now.
Basically I guess I'm kind of asking if the 55-200 is decent for the type of wildlife shooting I do, if it's much of an improvement over my kit lens. Also asking if it's worth it to get the 16mm for my wide angle and vista shots and gaining some astro ability, over sticking with my 18-55 for landscapes and gaining the samyang for astro.
Any input for those that have used any of the above are greatly appreciated. I hope I covered most of what I shoot and what my main focus is.
