ruslan Posted December 1, 2013 Share Posted December 1, 2013 <p>As I see the price - it is going down in my country. <br />Here is a question - 1) does the rear display have anti-scratch coating? Or should I keep it from friction at clothes? <br />And 2) How does the Nikon adapter increase the crop-factor for Nikkor lenses? <br /><br /> The adapter is thick (according to the images online), so 50 mm lens is <em>not</em> 75 mm equivalent. </p> Link to comment Share on other sites More sharing options...
tjfuss Posted December 1, 2013 Share Posted December 1, 2013 <p>Unless the adapter has optical elements, it should have no impact on the crop factor at all. The physical size of the sensor in the Fuji is smaller than a full 35mm image frame causing the "crop" factor of about 1.5<br> A 50mm lens used on the Fuji x-pro 1 would have about the same field of view as a 75mm lens on a full frame 35mm (or full frame DSLR).<br> I don't know if Fuji used an anti-scratch coating. I've not had any issue with the X-E1 but my camera rides in a shoulder bag more than around my neck.</p> Link to comment Share on other sites More sharing options...
ruslan Posted December 1, 2013 Author Share Posted December 1, 2013 <blockquote> <p>Unless the adapter has optical elements, it should have no impact on the crop factor at all.</p> </blockquote> <p>Wrong. It does. The aadaptor <em>has</em> its thickness. <em>The thicker the adaptor</em>, the more it does influence on increase equivalent FL. <br />Try to move the lens off the body at least 2-3 mm looking into the SLR VF (any camera) and you will notice how the image dramatically gets larger and the angle of view narrower. If the flange of the lens were attached to the flange of the camera's mount (without an adapter) - it would be 1.5 crop factor. </p> Link to comment Share on other sites More sharing options...
andylynn Posted December 1, 2013 Share Posted December 1, 2013 Think of it this way. The lens is designed to be mounted a particular distance from the film or sensor. This is called the flange distance and it's the same in all Nikon SLRs regardless of crop size - 46.5mm. This is the distance from the plane of the sensor's sensitive surface to the plane of the mount ring. On the Fuji X line the flange distance is 17.7mm, so that's a 28.8mm difference. A well made Nikon F to Fuji adapter must be 28.8mm (a bit more than an inch) thick. If it were a bit more thick, the lens would focus closer than intended and not hit infinity focus. Not thick enough and the lens will not hit its intended close focus and will focus past infinity. Timothy is of course correct. When using a correctly made adapter with a Nikon lens on an X-Pro1 the distance from lens to sensor is the same as it would be if the lens were mounted on, say, a D7000. The crop factor would be the same - 1.5x - because the sensors on those two cameras are the same size. Your manual focus 50mm lens would have the field of view of a 75mm lens used on an FX camera.

andylynn Posted December 1, 2013 Share Posted December 1, 2013 Also, the LCD is glass. It won't scratch under normal circumstances but you can scratch it by dropping it or with metal objects. If you're concerned you can get screen protectors - plastic film that sticks on, and if that gets scratched you can easily replace it. Also, for use with adapter lenses check out the X-E2. It had a higher res and faster refreshing EVF than the Pro1 and you can't really use the OVF option in the Pro1 when manual focusing anyway.

wmervine Posted December 2, 2013 Share Posted December 2, 2013 <p>The only adaptor I know of that would address the difference in angle of view between full frame (35mm film) and crop (DX, Fuji X) is the Metabones speedbooster. Otherwise all other adaptors would still leave you with the equivalent angle of view as you would obtain from a Nikon DX body. Having just moved from Nikon to Fuji I have spent the last while researching and shopping and didn't find any other options to change your angle of view.</p> Link to comment Share on other sites More sharing options...
andylynn Posted December 2, 2013 Share Posted December 2, 2013 There's actually also a speed booster knockoff called lens turbo that sells cheap on eBay. It's not an exact copy - the crop factor is a bit different and the image quality is degraded a bit. And of course you could also try simulating the effect of an adapter that's too thick by putting an extension tub between the lens and the adapter...

zelph_young Posted December 8, 2013 Share Posted December 8, 2013 <p>Just be aware the X-E2 is smaller in size than the X-Pro1. Enough so that some of us don't like it at all and use the X-Pro1 instead. It is a matter of which is more comfortable in use which makes a big difference in our images. Fighting a camera that is too small is not fun. Since getting the X-Pro 1 things are much better.<br> Both produce good images so it is a personal choice.</p> Link to comment Share on other sites More sharing options...
