i have Nikon D90 and I want to buy lens 50mm 1.4 Which one is the fast lens to focus, F/1.4 G or F/1.4S ? what are the main difference? pros and cons.

It is a close call. The f/1.4G has slightly faster AF, but if you use the lens comparison tool on DxOMark.com, the f/1.4 D scores one point higher for overall performance on the D90 body. If you plan to upgrade your camera, the f/1.4 G is a better performer on higher resolution sensors, making it a better investment for future use.

I have the Canon 50 f1.4, the Canon 100 f2.0, the Canon 135 f2.0L, and this lens. I recently sold my 24-105 f4L. I use primarily the sigma 35 art or the 135L, it depends on what I am shooting. I do love this lens though. It is sharp and fast.

My opinion goes against some other comments. I use a Sigma 150-500 and Sigma 70-300 (the newer version) on my D7100, shooting motorsports, where the speeds reached are quite a bit higher than kids playing football, and the focusing speed is very good, especially on the 120-300. I've never lost a shot due to slow focus, even when panning as the cars go by at 150mph+. I've used the 20-700 Sigma, and it's even a bit faster.

There is at least one good comparison of the two lenses on youtube. Check out the videos and determine for yourself which lens fits your needs better. The f/1.4 is my first non-L lens; the add'l cost and weight made the f/1.2 less of a good fit for me.

Do you mean fast as in how quick it grabs autofocus? If thats your question, i dont know about the 35 but this is pretty quick. If you were asking about the max aperture, well, this is a f/4 glass so its not as near as fast, but they re two totally different lenses for two different purposes.

The f4 is a super good all around lens and pretty nice for wildlife etc. More of an outdoor lens. If you're more indoor, portrait, etc, go for the 2.8. It is much larger however. I went with the f4 first because it gives more range of use.

I find the 85mm a bit faster in focusing *if* you're a fair amount of distance from your subject, as is intended with what's essentially a portrait lens. If you try to squeeze a macro shot out of it, the auto-focus just grinds back and forth trying to get a lock. That said, I have an older model 50mm 1.4 and never found the speed of focus (with a D3S and D800) to be outrageously slow, so take that into consideration with my answer.

The lens is extremely sharp in all light. The F2.8 lens is only marginally sharper but 1 stop faster and if low light and not cost or weight is important, then for low light get a "faster" lens. I use a D800 and am amazed at the performance. I got the F4 after trading in my 2.8 lens to reduce the weight of my gear (and size of lens).

Hi the autofocus is fast. This is a relatively fast lens. you can google to compare with the latest lens 58mm f1.4 which produces stunning shots. But this model of 50mm f1.4G is a good lens to use and nice bokeh. Generally no lens will get stuck. I reckon you meant hunting or trying to focus. Every lens has a min distance of focus. Like someone who is long sighted, if you are too close you will not be able to focus. I think this lens is around a foot distance. Check the specifications.

I've owned both lenses and the 50 1.4 has a better build quality, the larger aperture will also give you shallower DOF which might help with portraits, and it should focus faster. Unless you plan on doing a lot of macro photography with your lens I'd go with the 50 1.4.

Nikon AF-S FX NIKKOR 28-300mm f/3.5-5.6G ED Vibration Reduction Zoom Lens with Auto Focus for Nikon DSLR Cameras (I love this lens!!) And my other favorite lens is a Nikon is the Nikon 50mm 1.4. It's cheap and I love having it on my camera... a bit soft sometimes but that's my style.

The 50mm f/1.8 will be able to gather more light than the 35mm f/2.4 and will provide a "nicer" bokeh so it is better suited for portrait photography (indoor or outdoor). It's main drawback compared with the 35mm with be the field of view (50mm becomes a 75mm whereas 35mm becomes approximately a 52mm on pentax DSLR). What it means is that in a close and restricted environment you won't be able to put everyone in the frame. Outside, the 50mm is better, inside, it depends. For kids sporting events you might want to use longer focal length (at least 100mm or higher) and fast lenses if the event is indoor (at least f/2 or lower). I wouldn't recommend any of the ones you talked for this. I have both a 50mm and a 35mm. I love both, and use them both during family gatherings or things like this. I also use my 35mm for landscape photography. Honestly it's a matter of taste.

HelloWell as you can see the Rokinon cine lens 35mm t1.5 is made especific for video and cine cameras, the rokinon 35mm f 1.4 is for still pictures, keep in mind that F 1.4 and t 1.5 are not the same apertures also the rokinon cine lens series that aperture ring is declicked allowing a more smooth transition in apertures when shooting movies. They are both excellent pieces of optics but one is more suited for videos and movies than the counterpart of the same size. Hope this answer your question. Thanks.

95mm filter size. Do remember that this lens is f/5 up to about 170mm and at 420mm is already f/6.3 so it's not "fast" if you're considering using filters not light-friendly.Cheers.

See if you can find this particular lens with the "AF-D" designation (vs plain old "AF"). On this particular lens model Nikon changed the AF gearing resulting in autofocus that's much faster. (D does not signify an AF speed increase on other Nikkor lenses, just this one -- it's a designator that indicates that distance info is passed to the camera.)

The fast aperture on either of those lenses is going to be unimportant for a landscape shoot such as the grand canyon where you will likely keep your aperture at f8-ff16 to maximize your depth of field. You can accomplish this with a 24-70 2.8, 24-120 f4 or a variety of others. Having said that, the 24 1.4(which I use) is one of Nikon's sharpest lenses and except for the price has no real negatives. The 28 1.8 is a nice budget alternative although that extra 4mm might be missed on landscape shoots.

I have both the 50mm f1/8 and 40mm f2.8 lens. Both have very short DOF so you have to be careful of your focus. The 50 mm is slightly cheaper but I would rate the 40mm a 4.4 out of 5 and the 50mm 4.2 out of 5.
