My primary focus is landscapes and have also really caught the astro bug bad. Otherwise I love photographing birds and any other wildlife that presents itself. I have zero interest in video and photographing people. So fairly diverse requirements but
My current budget is about $2500 Canadian
I think I have my lenses figured out
Sigma 17-50 f2.8 OR 18-50 f2.8 (haven't decided between the two) $250 CAD
Sigma 70-200 f2.8 $750 CAD
Sigma 150-600 Contemporary. $1100 CAD
I would buy a body and the first 2 lenses and then save for the 150-600 over the next several months or even the next year. It would be a fun toy but not as critical as the first two.
The 3 bodies I am considering
D810 - $1300 to $1500 Canadian Dollars
D750 - $1000 Canadian Dollars
D7200 - $600 Canadian Dollars
Here is my thought process:
The above prices do not include shipping and taxes. And in the case of the D810 the purchase of a CF card.
I like the D810 over the 750 due to the lack of AA filter and higher MP. But if you add it all up, the 810 blows my budget by a few hundred dollars, the D750 pretty much nails it directly.
The D7200 is very budget friendly and the savings would allow me to buy a star tracker at the same time. I currently use the Pentax's astrotracer but that only works on my Pentax body. I have in the past used a barn door mount as well, however I prefer automated if I can.
Any tips for my dilemma which I am drastically overthinking?
