Q: 3. I am looking at upgrading to a versatile full frame lens. I bought my d750 last year and I do a mix of portrait, still life, & travel photography. Eventually my goal is to expand my lenses and have a few primaries because I prefer those in my cropped lenses, but for now due to what I can afford I really just want a one and done lens that I can pretty much use for everything. I’m having trouble though deciding between the 24-85mm or 24-120. Does anyone know which would be more beneficial or know about either more in-depth to help me decide? The price difference in the used department is only about $100 which isn’t that big of a deal to me but I want to make sure I am getting the best one for what I need right now.

A: I would recommend the 24-120mm lens, it is more versatile and image quality is better with faster focusing.

Q: 9. I am into portrait,event & wedding photography.( an amateur turned to freelancer & now want to be professional). I own presently- *Nikon D 7100 with the Kit Lens 18-105 mmVR + 50mm f/1.8 + Nikon 70-300 VR. I generally shoot Indian Weddings with Elinchrome Strobes & Nissin Di 866 Mark II Flash. I am planning to get a FX ( D750 most likely) in near future. Now, I want to upgrade to a lens which will be a better one than the 18-105 Kit, must be a FX lens at the same time as I dont want to invest further in DX lens. I will retain my D 7100 as my second body,when I upgrade to FX.If not mistaken a lot, I think I have few options to choose from ( I have a budget concern too)-Nikon 24-70 f/2.8 ( non VR or VR,both are out of reach financially now), Tamron 24-70 f/2.8 VC & Nikon 24-120 mm VR.My CONFUSION / QUERRY -** Which is better,in terms of reliability , quality assurance & service -Tamron 24-70 f/2.8 OR Nikon 24-120 f/4 VR ?** Is there a HUGE Difference in the image quality/ bokeh / sharpness of both the above lenses,if suppose both are shot at f/4 ?** Will Nikon 24-120 f/4 VR produce noticeably better result than the Nikon 18-105 mm in D 7100 ?** Given that I mostly use external light sources like Elinchrome or Flash, will I miss the f/2.8 too much ?** Is it wiser to invest in 24-120 VR + Nikon 85 mm f/1.8 G rather than one single 24-70 f/2.8 ?Ranjan KM

A: Hi Ranjan: OEM (Original Equipment Manufacturer) is always more expensive than off brand, but the real advantage are near perfect match between lens and sensor. Off brand may save you some money, and some of them are quite good, my recommendation is, if you can go with the OEM, do it by all means. All the lens you mentioned offer better quality than the original kit lens, and one major reason for a FX lens on a DX body has the advantage of taking the best image area FX can offer, and if you are going to the D750 body, now the game comes down to considering flexibility, image quality, build consistency and focal length versatility.The 24-70 is an outstanding piece of optical engineering, if you could still find the original version (i.e. Non-VR), the bundle you save I would suggest to put it to a solid tripod like Gitzo or the like. You also mentioned you use light set up, the F2.8 may or may not be a game changer for you.concerning bokeh, the larger the aperture, the better.The 24-120 on the other hand, is cheaper, its major advantage is when you are shooting beyond 70mm but not quite up to 120 you have that extra 'reach' without the need to changing to 70-300mm, which itself is a good lens minus nano coating--and I hope Nikon will have its update version with Nano coating someday.That extra 50mm reach will benefit you a great deal, other than saving on cost. You did not mention how many camera bodies you plan to acquire, but if you are using a single D750 as your main body, it will be a very versatile wedding photo tool.Haiving said that, if you can bite the bullet and go with the 24-70, yes, there is an image quality diference between it and the 24-120.
