So sánh canon 24-70f2.8 và 24-105

The question is simple I guess… between THOSE 2- which one?…. I didn’t ask what lenses I need for specific type of photography

It was a simple question. I always prefer to give considered advice, and in this situation I requested more information, being (your) outcome information and (your) existing kit, so I could refine my advice into an effort better suit your situation.

However, that information being withheld, I can speak to my position.

I did buy the EF 24 to 105 F/4L IS USM and subsequently, when both were released and I used both of the newer lenses, I did not see a need to buy the EF 24 to 105 F/4L IS USM MkII or the EF 24 to 70 F/4L IS USM.

Pros and cons relevant to me, my usage and my gear:

Pros:

The EF 24 to 70 F/4L IS USM is generally a tad sharper than either of the 24 to 105 lenses mentioned.

Nếu đang dùng 60D thì ko nên mua 24-70 hay 24-105 thì 2 lens này phát huy hết tác dụng trên FF chứ ko phải crop. Nếu bác muốn thì có thể thanh lý lens 17-50 của bác, mua lens Canon EFs 17-55f2.8, con này là king of crop, tương đương 24-70f2.8 trên FF. Còn nếu ko thì con 15-85 cũng là 1 lens rất ổn, tiêu cự tương đương 24-105 trên fullframe bác ạ.

Còn nếu nhất định phải chọn 24-70f4 và 24-105f4 thì em sẽ chọn 24-70f4. Cả 2 lens này em đã chụp qua trên 6D. 24-105 ra đời đã lâu, nhiều khuyết điểm, nhất là build hơi tệ, hay bị tụt zôom khi cũ. 24-70f4 mới ra, cải thiện đc build rất nhiều, có chế độ macro, công tắc khóa zoom để ko bị tụt zoom. Cầm trên tay cực chắc chắn. Chụp phong cảnh thì 24-70 cho ra tia đèn, tia mặt trời rất đẹp, 24-105 ko có đc cái đó.

Before upgrading to MILC, I owned a few DSLR body's. I purchased many, many lenses. Over time, I realized I had too much overlap in FL and aperture (way too much). I sold a great deal of my lenses, kept my favorites and a few others for special purpose. The second time around, I was very particular about what I bought.

I ended up with an EF trinity. Once again I added a few primes and special purpose lenses to compliment. When you look at all the factors, investment, performance and what you are able to use at any given time (one lens) unless you have more than one body, the amount of money you spend buying a bunch of lenses vs, a few really good lenses almost evens itself out in the end.

The 24~105 f4 is a good lens. The 24-70 f2.8 costs more. In the end, its a higher performing lens with the ability to adapt itself to more shooting situations. Constant f2.8 through its entire range vs. variable on the RF24~105. There are enough reviews of both out there with the consensus clearly in favor of the 24-70. The shorter FL lens is slightly sharper, and it beats its rival by a small margin. There is more to it though. The key question is exactly what Ernie asked. Example, if you walk inside a building with the f4, you might need a flash, you might not with the f2.8. Conversely, if you can't get closer to a subject that margin of additional reach might be handy at the cost of background blur, ISO performance or separation.

From my perspective, I'd ask how many other RF lenses do you plan to purchase or do you already own? I only own 4 RF lenses now. I plan for a 5th, and that will likely be it. I'll have FL coverage from 15 ~ 200mm with constant aperture, a super light 100~400mm (non L), and something 200~(somewhere between 600-1000mm) hopefully if Canon Rumors is accurate. My bag is lighter, less to pack and carry. (Wallet is not however) but I know I have the best tools available for almost every situation, regardless of lighting, distance to subjects, etc. This level of planning has greatly improved my love for photography and my hobby. What I believe you want to avoid (as much as possible) is overlap. Another lens, "So I can do such and such". In some instances, it cannot be avoided. In many cases, spending more upfront ends up being the wiser investment in the long run. I also recognize and understand budget and cost as being deciding factors when making these decisions. I would buy the 24~70. This is my walk around lens. (Landscape and Architecture) I can shoot fountains outside or walk into a dark museum without a second thought. Art, no flash allowed is no problem. I can get the shot. Or, I can carry a prime with a better aperture, but I'll have to swap my lens on the go. Not always easy when shooting conditions are changing constantly. I hope this provides a slightly different perspective and helps with your decision.
