At the same aperture both should give the same shutter speed.
Add in the fact that the company is strong in terms of backward compatibility (those manual focus lenses from the 70s work on modern digital bodies just fine) and alabama medicaid billing guidelines builds shake reduction into the body so that every lens is stabilized, and you have.
You can argue that the optical quality of an older manual focus lens might be better that that of a similar EF lens, but I haven't found that really to be the case, at least with comparable optics.However, it will cost you around 1700 new (the Canon EF20/2.8 is closer to 400 so it's certainly not a cheap or convenient route to optical quality!Here it is: If you can get an adaptall mount for Pentax Universal Screw (M42 and a Pentax Screw (M42) to EOS adapter you can couple them togther and mount any Tamron adaptall lens on any EOS body!Since a mechanically adapted manual focus lens has corel draw book pdf file no intrinsic electrical coupling to the body, the body doesn't know it's there and so with most current EOS bodies the LCD display will readout an aperture of "00".The only downside is that it's time consuming and you can't do it with the camera up to your eye.Third-party lenses fill some of those gaps, although lens makers like Sigma and Tamron can sometimes be slower to release a new lens for Pentax systems when compared with Canon and Nikon.No levers to couple aperture settings, no automatic stop down on shooting, no mechanical contacts, no focus drive.You can find some very inexpensive Pentax screw mount lenses.This disrupts the communication between the multiplier and the camera and the camera is happy again.You can also find very expensive german/swiss/japanese made adapters costing up to 200.
The two aren't the same T-mounts are generally a simple mechanical coupling between a lens and camera.
A mechanical adapter which allows a lens to be mounted on an EOS body and focused to infinity is only possible if the lens is designed to focus an image at a distance greater than that between a standard EF series lens and the sensor.
The.4 is 2/3 stop faster though.Optical quality may not be the highest, but then neither is the cost.Either that or do not lock the adapter completely in the EOS mount.These lenses can be used with adapters that don't depress the pin if they are switched into Manual aperture control mode.Pentax 50mm.4 Super-Takumar M42 mount on eBay (credit: g#filelinks) I think the answer is generally no, not unless you have to for reasons of cost or unless you just like playing around with old lenses.Examples are: If you can live with manual focus and stop down metering and you don't demand the very highest optical quality, some of these lenses represent good value.For almost all manual focus lenses, this stopping down during exposure is accomplished mechanically via a lever which is moved as the cameras mirror flips.Stop Down Metering, in most SLRs and dslrs, focusing is done at full aperture, and if you set the aperture to, say, f11, it remains fully open until just before exposure, then it stops down for the exposure and opens up again.
