Lens question

[kharypayt37]

I currently have a t6i body with a 55-250mm lens. I mainly take sports pictures/videos (American football), and I am wondering which lens I should upgrade to. I am looking for an investment piece that will suit me down the line should i upgrade my camera. From research the past few days, i have focused on the 70-200mm f/4 IS II. This has been the clear-cut favorite (according to the sources ive looked at). However, i am not sure if i should opt for a lens like the 300mm as my current lens can deal with those closer shots.

i appreciate any advice!

Greetings,

One important detail.

The 70~200 f4 is a EF lens

Your T6i is APS-C and is designed primary for EF-S lenses.  You can however use EF lenses with it, but note that the effective focal length will be 112~320mm (not) 70~200.

And the (35 mm equivalent view) effective focal length of his current 55-250 is 88 to 400.

Yeah pointing out it is an EF vs EF-S is, well, pointless!
However I am not sure I would do it unless you think the slightly better f4 aperture will help you.

I had and used two Rebels with that lens, EF 70-200mm f4 L, for years and it worked very well for me. Keep in mind to gain the better f4 aperture you will give up 55mm of FL. For daylight football I am not sure that is a good trade perhaps for night time it would be.

You make it sound like the crop factor does not apply to his EF-S 55-250 lens. You should also point out that his current EF-S 55-250 has an effective focal length of 88-400mm (not) 55~250.

Where is your current lens holding you back. You would lose some reach if you get the 70-200 but gain one f/stop - less noise with the same shutter speed or faster shutter speed with the same noise. 

The 300mm lens (I'm guessing the f/4) will give you a little more reach compared to your current lens and an additional f/stop.

The 55~250 is EF-S (true APS-C)

@Mike...

Crop factor...  It doesn't apply.  

He's got an APS-C body and is considering an EF lens.  (70~200)

It doesn't matter what lens you use. Crop factor ALWAYS applies when you use a crop camera. It is a basic fact that is often misunderstood.

I believe his intention is to improve the quality of his glass.  now and in the future.  He indicated he was conidering the 70-200, but then stated that a 300mm lens was also in contention, recognozing that his 55-250 would already be covering this focal length.  

I was merely pointing out that using an EF lens with his body will yield the following FL, not what range on the lens shows.  What going to change is the FOV and amount of light an EF lens will let in.  The image circle is going to be smaller on the crop body regardless of the lens being used.  I'm aware of this.  Maybe I didn't express this correctly.
