Steve, I measured the TFoV of my FPO Bk7 Rangemaster yesterday evening at 10.3* to 10.4*. So it would appear that the FPO Bk7 and BaK4 Rangemasters have the same TFoV. Graham

Steve, Of the binoculars in your list I only have the Tasco 400 and a Bk7 FPO Rangemaster but I should receive a Cory Suddarth reconditioned Bak4 FPO CF Rangemaster within a few days, apparently this particular glass is a very good example of its type. I'll measure their TFoV using the angle...

Steve, Have you measured the TFoV of your wide angle 7x35s? My experience is that the actual TFoV is typically 0.5* - 1.00* less than that claimed on the prism plates. Graham

Henry, Ok - I have several vintage 7x35s and will write a short comparative report on their various merits etc when I have time later this year. How is the cement in the objectives and oculars holding up? Thank you again for the clarity and comprehensive nature of your report. Graham

Henry, Excellent report - very interesting reading - thank you. In your view, how does the Rangemaster's quality compare to other wide-angle binoculars of the same vintage? Graham

Simon, I will also be very interested to read your comparison. I have an FPO Bk7 here but my FPO Bak4 is out on loan for another few weeks. I should have it back sometime in January when I'll do a comparison. Graham

Henry, Yes I feel sure that's what it must be but I have no idea how many elements it has. Unfortunately, I can't inspect one as I don't have one here at the moment. However, I do have one incoming which should be with me in about 3 weeks. Graham

Henry, Yes, the booster slides over the objective ring. They are 2.5x so yield 17.5x when attached to a Rangemaster. There appear to be at least two variants depending on the method of attachment: one is a push fit held in place by three small rubber buffers, the other is clamped in place by a...

I think that there were at least nine distinct Rangemaster models: FPO Bk7 IF FPO Bk7 CF FPO BaK4 IF FPO Bak4 CF FPO Bak4 silver trim IF FPO BaK4 silver trim CF Tamron conventional-style version Tamron custom-style version, strap lugs attached to prism covers Tamron custom-style version, strap...

Steve Actually the Bk7 and Bak4 FPO Rangemasters are readily distinguishable by the screws - or lack of them - on the prism cover plates. The Bk7 doesn't have them but the Bak4 does. Graham

In a 1952 ad Bushnell claim for the Rangemaster that "All air-to-glass surfaces hard coated" As the ad was placed in 1952 I imagine this applies to the earlier BK7 model, rather than the later high-index models under discussion. Nevertheless it seems to me unlikely that Fuji having fully...
