About this deal

The good news for MFT is that vignetting isn't an issue like it is for FF. Compared to larger formats, MFT images look very even across the whole frame in nearly all IQ properties. So, if edge-to-edge consistency with a bit of softness overall is your thing, MFT is a great choice. Personally, I don't see a real advantage to MFT when bigger-sensor bodies are neither more expensive nor bigger, offer wider view angles with the same lenses, and have sufficient pixel density so that an MFT-sized crop would still give you pretty much what an actual MFT sensor delivers with old lenses... but no doubt moderator Tom will post a response to this about how much better he feels MFT ergonomics are... or you can just imagine he posted that and we'll save him the effort. Anyway, my point really is that MFT folks have to hunt to find lenses that look sharp at the pixel level, while FF users worry more about vignetting and corner performance in general.

Anyway, my point really is that MFT folks have to hunt to find lenses that look sharp at the pixel level, while FF users worry more about vignetting and corner performance in general. Above: For comparison, here’s the older EF 70-200mm f4L again showing its length, further increased by the adapter. Note the looser-feeling zoom ring and the wider manual focusing which is mechanically-linked while also showing focus distance in a window, while the RF lenses display it graphically on-screen. Above: And now for the RF 70-200mm f4L again at 200mm and from exactly the same distance where the difference in magnification is quite striking. But the new RF lens can focus much closer, down to 60cm from the focal plane. The 200-4R and the 700R4 transmissions were both released in the 1980s. At the time, there was a high need for cars with fuel economy and as such, the duo became the answer to the growing need. 2. TV Cable Above: Interestingly the RF f2.8L model seen here positions its control ring closest to the lens mount and swaps the position of the focus and zoom rings.Have it and find it impressively sharp. But, mine, and apparently all samples, has extreme zoom creep. I can't point it up or down more than 45° without it slipping, which makes it a PITA to use. One of the most notable differences between either is in their overdrive gear. The 200-4R transmission has a .67:1 which is considerably more aggressive than the 700R4’s .70:1 overdrive gear. An overdrive gear of this nature on the 200-4R is equivalent to a low RPM when one is driving down a highway. Here’s a more precise breakdown of the overdrive gear ratios of both transmissions: First Gear

Minimum focusing distance is a little high for Version 1 (the one with a chrome-colored ring) at 1.6 m These lenses also vary a lot in size and handling. For example, the Soligor is appealingly tiny while the exceptionally well-made and heavy Kiron would make a very effective weapon in a cage fight. There are also unique differences between the 200-4R and 700R4 transmissions and some of these include: 1. Appearance Above: Comparing the far corners and again it’s a very close call. Arguably the RF lens is a fraction sharper, but I wouldn’t complain about the EF performance here, and again if you’re shooting a landscape you could always stop down to f5.6 or f8 to match the quality. Above: so here it is now from its own closest focusing distance where if I toggle between the two lenses, you’ll see the newer RF model actually delivering almost the same coverage, in fact a fraction tighter.

Second and third phases: advanced BCMS and standard BCMS

Above: And now to the corner where the RF is a little sharper, but there’s not much in it. Closing the aperture a stop or two makes them pretty much identical in the corner. In my experience, the various Vivitar Series 1 f/3.5 or f/2.8-4 are all good, with my 5th version (Q-DOS) best (unless you put it in Q-DOS mode, in which case it's terrible). My Kiron 70-210mm f/4, Minolta Beercan, Soligor C/D 80-200mm f/4.5, and Minolta MD 100-200mm f/5.6 are also all solid "A" performers although there are various differences. Similar in build to the TH350, the 200-4R proved to be a great updateto the outdated 3-speed transmission in builds where an overdrive gear was a must. Eventually, in 1990, the 200-4R was phased out for the 700R4, and later iterations of the same transmission including the 4L60 and 4L60-E. Rundown on the Numbers As good as a transmission can be in its pure and intended form, nothing beats what a custom build can get you. And with the right aftermarket parts and some effort from a GM transmission expert, the 200-4R can go from being an aluminum transmission straight out of the 80s, into being a 21st-century powerhouse for performance-oriented muscle cars, complete with a reliable overdrive and heavy-duty materials. Easy Installation. Another great feature s that it has easy installation and is surprisingly affordable. Capable of handling around 250-400 HP, and is the same length as Powerglide and TH350 transmissions.
