I had yet another thought...
Since you are looking at studio only and like to work at closer range, then you might want to consider an 8x10 camera with a 4x5 reducing back... And I'm sure the Deacons of the forum will flame me for even suggesting a beginner consider this, but...
1) With an 8x10 you can get a 4x5 reducing back and use it just like any 4x5 studio camera;
2) 8x10 cameras in standard trim come with significantly longer bellows than a comparable 4x5, which makes it easy to use longer lenses at high reproduction ratios;
2A) Yet almost all of them will easily collapse to where you can still focus a 150 or 120 at infinity and a few to where you can focus a 90 at infinity;
3) As you get into LF you quickly learn the advantages inherent with larger negatives and most will agree you can see differences between 4x5 and 8x10 even in 16x20 prints.
BUT!!! There are some negatives aside from size weight:
1) 8x10 cameras are going to cost say 50% more used than a comparable 4x5;
2) Most 210 lenses for 4x5 will cover 8x10 at the closer focusing ranges you are talking about, but wont be ideal. So a 300 would be abetter choice. The minor good news here is there are some relatively inexpensive (sub $500 range used) yet excellent lenses in 12" (300mm) lenses that cover 8x10 with room to spare, like a Kodak Ektar, convertable Symmar or even possibly an older Fujinon 300 C.
3) 8x10 film and processiong is more expensive than 4x5 -- but only about 2x the cost for 4x the film area.
Only offered FWIW,
