Hey folks, Matt from rtotheimage.com. We've got a question in here from Graham and it's an interesting question. I've discussed it before about, we haven't really talked about it for a while so I read this and I thought that's a good question and one we should talk about. Nikon 85F18G or Nikon F14G is the 1.4G worth the additional cost. That's the heading of the email but you can in shooters or Sony or anybody else. We could just remove the brand here and say F18 versus F14 is the additional speed worth the additional cost because that really is what it comes down to in almost any situation I could think of. Most of the times and especially with the Nikon F18, the 85F18 and the F14, they're just as sharp, sometimes even sharper on the F18. Usually the bouquet is just as good quality and it is in this situation, same with the 50s and you're just really paying for the speed. So he says, Hi Matt, love your channel, the reviews and your responses are brilliant. I'm a very keen photographer shooting mainly portraits and landscapes. I've recently purchased a Nikon D850 which I love and still have my D7200 which I also love. Both are fantastic cameras. I'm looking for a good full frame portrait lens. I use the Sigma 17 and 50F28 on my D7200 and I'm now looking at a good portrait lens for my D850. I'm considering either the Nikon 85F18G or the Nikon 85F14G is the cost of the one F14G worth it since it's almost four times the price of the one 8G. I'm currently using the Nikon 24 to 120 F4 on the D850. I enjoy your reviews and thoughts and your thoughts will be much appreciated. And so that's Graham writing in. Thank you for your question Graham. I guess you can probably already see where I'm going with this with the introduction. F14 vs F18 is it worth the additional cost? Only if you need it. That's really the only answer that's valid here especially in this specific example though this would directly pertain to the 85F18 from Canon and then getting into the more expensive ones I think they even have their F12L at that point. And you're really paying for speed because the F18s are still very nice lenses, good quality especially specifically in this Nikon situation I love the F18G and in this situation no I'd never have felt for myself that the F14G was worth the additional cost. Now there's other people out there that would say oh no no no the F14 I need that and that's fine I'm not negating that. For my situation the F18 is all I need. I'm happy with that speed it's just as sharp as just as nice bouquet I just don't need to pay the extra for the speed. I mean speed fast lenses really are from the times when we had really slow film where you could barely get 800 ISO. Now we've got cameras like the 850 that can shoot at huge ISO levels and you really don't you know all you're going to get is speed in the sense of a faster aperture so you can shoot in lower light situations and that also gives you shallower depth of field. If the shallower depth of field is a big thing it's very pertinent to the way you shoot or that extra speed because you're in very low light and you want to keep your ISOs lower even though these cameras are really capable then that's why you would spend the extra money. Short of that no you just go with the 85F18G it's an fantastic lens I love it I have it here I shoot it on all the full frame bodies. So that's what I would say really like the 24 to 120F4 VR by the way that you said you shoot it with the 850 it's a great lens. So that's my thoughts the I also really like the Sigma 17 to 50 F28 on your 7200 that's my number one choice for a crop sensor body and either Canon or an icon. So and this this would hold true to with the 50s I mean I have a F14D from Nikon but I got it for less money than I it was like virtually brand new it was used but I got it for less money than an F18G was worth. That's the only reason I did buy that one but normally if I was just buying new and I was looking at the two I would get the F18 on the 50s as well. Same with the Canon's the 50 F18 is very nice I would venture that when you're getting into some of the F1 twos in the Canon side you are getting into a little bit better quality both build quality and image quality and the Nikon side with these two not really you're getting just as nice a lens you're just paying for the speed. Let me throw back to you guys you guys agree with me just paying for the speed and then hence for the ability to shoot in lower light and get a shallow redept feel or do you think there's other advantages or do you think you know let us know let us know what you think in the in the comments below F18 versus F14 in this specific situation Nikon F85F18G versus Nikon F85F14G is a worth the additional cost. Look forward to hearing what you guys have to say thanks for your questioning Graham and stay tuned we'll be back soon here at rdtheimage.com.
