Above: Next up the view at 135mm, starting with the RF 70-200mm f4 which in the middle again looks very sharp with no benefit to stopping-down further. Moving into the corners again reveals the excellent performance of the lens with crisp details at f4 and again little benefit to closing the aperture further. Above: And finally the view at 200mm from the RF 70-200mm f4, and completing a story of excellent performance, you’ll see there’s sharp details in the centre which again don’t benefit from stopping-down, with that crispness extending into the corners. Obviously as a telephoto zoom, the depth of field can become quite shallow, so for landscapes you may prefer to stop-down, but these tests show the lens can perform very well when wide-open. Above: Ok so how much smaller are we talking? Here’s the most recent EF 70-200mm f4L Mark II in the middle, set to 200mm, joined by the RF 70-200mm f4L on the left, also set to 200mm – notice how they’re almost the same length when zoomed to 200mm, and for good measure, the RF 70-200mm f2.8L on the right, also zoomed to 200mm where it’s a couple of cm longer. Despite this, they are still a great choice of transmission if one is looking to increase the MPG (Miles Per Gallon) and reduce the RPM as the vehicle moves down the highway. Your choice of which should be determined by the use you want to put it to. vs. 700R4 transmissions are two four-speed automatics that are always compared side-by-side for their similarities, yet unique differences. They may have been released in the 1980s, but where one fails the other makes up for it. It’s also worthy to note that the 200-4R vs 700R4 strength has been improved from what they were a couple of years ago.

Reduced Fuel Consumption. Overdrive transmissions make better use of fuel because the car’s engine speed decreases when using overdrive gearing. In addition to having improved fuel efficiency, there is less wear and tear on the vehicle. for the Tokina SZ-X 80-200 f4.5-5.6 lens. Of the 15 or so 80-200mm manual lenses I have, the Tokina is of the smallest 80-200mm lens that I have - very petite, and very sharp. I also have the Soligor C/D 80-200mm, f4.5 - also small, but IMHO, not quite as sharp as the Tokina. 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 Today, many vehicles still use the 200-4R transmission to give older cars an overdrive gear and more horsepower. Features of GM 200-4R TransmissionsThe new standard offers others advantages: “It allows better scalability of the company’s own resources deployment,” which Jung describes as follows: “For example, you can start with the especially time-critical processes and protect everything that must not be allowed to fail for even single day, and you then find your way forward from there, e.g. you then look at everything that shouldn’t be unavailable for more than three days, and so on.” If you are considering putting a 200-4R transmission into your older vehicle, here are a few things you should know.

200-4R Transmission: The Holy Grail of Power, Fuel Efficiency

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 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: So far so similar, but unlike the internal zoom on the EF model in the middle, the two RF lenses flanking it employ extending barrels which retract when zoomed to 70mm. So with all three lenses now set to 70mm, notice how the two RF lenses have shrunk considerably, compared to the older EF lens which has of course stayed exactly the same size.First, you need to count all the pan angles and if it is a 6 angled, then its definitely a 200-4R. On the other hand, it is a 700R4 if it has is equivalent to a 4 angled square. It also has a bigger pan and longer tail-shaft length than the 200-4R 2. Gearing 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. 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. Above: In terms of materials, the RF 70-200mm f4L employs engineering plastic for its barrel rather than the mix of metal and plastic for the EF version. Again I’ve not dropped or banged either lens, so can’t say whether one’s tougher than the other, but don’t assume metal wins for this kind of job. Canon’s adopted engineering plastics for all of its RF lenses so far without issues. Conversely, the 200-4R can be made to be stronger than the 700R4. It is, however, worthy to note that the 200-4R is popularly known as the weaker of the 200-4R/700R4 pair. Conclusion

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below. Above: Moving onto autofocus, the RF 70-200 f4L employs dual Nano USM motors, allowing it to focus closer than the old EF version as well as operating more smoothly and quietly.In my tests – demonstrated in the video review above – the RF version focused a little faster than the EF model and felt more confident too, whether photographing objects, people or wildlife. Another reason to revise the standard is to make it more accessible through simplifications. “The focus is on newcomers,” stresses her colleague Daniel Gilles, deputy project manager. “The standard is as easy as possible, so you can also just use it as a guide to get you started,” he adds. It therefore provides numerous document templates. “You can simply take these and fill them out,” says Gilles. The same applies for the other supplementary tools, including instructions about how to close any gaps you’ve identified or special considerations for IT emergencies.

The first obvious reason is the purpose the car will be put to. Is it for drag racing or street ride? If it’s for drag, then you’re better off with 200-4R thanks to the closeness of its gear ratios. There are, however, two limitations to the 200-4R in this aspect. There are also unique differences between the 200-4R and 700R4 transmissions and some of these include: 1. Appearance Above: More importantly if you look closer, you’ll see the RF lens is much sharper at its closest focusing distance than the EF model, especially at the edges, so in terms of quality at close range it represents an upgrade, but don’t expect much or even any difference in magnification at their respective closest distances. 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. Highly resolving, very nice micro-contrast. I read that it was said to be better than the contemporary Nikon lens on specialized magazines, and it should be better than the SMC Pentax-A 70-210mm f/4 (which is more contrasty but has less resolving power).

Above: The RF 70-200mm f4L follows a similar strategy to the RF 2.8, employing an extending barrel to become much shorter at the 70mm focal length. This is in contrast to the previous EF 70-200’s which employed fixed barrels with internal zooming.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. Above: Weighing 695g, the RF version is also almost 100g lighter than the EF model (not including the adapter either) and works out roughly similar in size and weight to the RF 24-105mm f4L seen here on the right.
