Let me insert a praise for later GX/FX models here. Sure, they are expensive, sometimes VERY expensive. They are easily dismissed as simplified / lower manufacturing cost alternatives to previous models, with lower manufacturing quality (which is not true), plastic parts (also not true) and similar BS.
Possibly the only cost saving measure of those models is that the auto loading feature has been replaced by the simpler, non-auto film loading of the Rolleiflex T. That's a blessing if you ask me: no more film or frames wasted due to misalignment of the sensor roll, different backing paper thickness, or similar reasons.
Apart from that, the GX/FX have a very accurate, coupled meter and a bright, modern high-quality focusing screen. The lens is a multi-coated 2.8 Planar - as good as it gets - which takes the same Bay III accessories as earlier 2.8 Rolleis. As said above, condition is key. Because GX/FX are more recent and were never used by press photographers of earlier times, the condition is likely to be much better than most 2.8 C/D/E/F out there.
Only issue, their price. If you have the funds, I can only recommend those models.
