200mm or 250

Hello,, I was wondering if there is much difference between 200mm or 250mm

thank you. I am torn between the Pentax 60-250 at f4 or the Tamron 70-200 at 2.8 or perhaps the Sigma 120-400 for better reach.

I think it's more important to get the lens you like the images from better. All of the lenses you mentioned are a bit of a compromise (in IQ) in my mind, so I've opted for only primes above 135mm (i.e. K200/2.5 & F*300/4.5).

With those zooms, you may actually find that having the wider short end (60mm) is more important when you need it.


When I'm using my 200mm lens, I think there's no need for 300mm, but when I'm using my 300 I think the 200 is unnecessary. In other words, you can usually work with whatever you have between 200 and 300mm.

But if you work with a prime at 200mm and above you'll get more compelling photos, especially at 300mm:

300: PENTAX : Select a PENTAX interchangeable lens camera or a lens model

200: PENTAX : Select a PENTAX interchangeable lens camera or a lens model

60-250: PENTAX : Select a PENTAX interchangeable lens camera or a lens model

Do you need WR? Do you prefer internal zoom (70-200 are internal zoom, 60-250 are not)?

The DA*60-250 very sharp and can easily compete with any 70-200 at F4 and smaller. But you do lose 1 stop of light (so if that matters, consider that too).

Apart from stating the obvious i.e. 50 mm, in real terms of usage, I'm not sure the difference is enough to really worry about.

I would consider other things like primes, lens speed and handling, before the 50 mm of focal length.

Do you shoot mainly indoors or outdoors? The answer to this question should guide you to the right lens.

Hi Frank5

I have a DA* 60-250 f4 and an FA* 80-200 f2.8 and my opinion is that the extra reach (at both ends) is very useful and the loss of one stop matters very little (to me at least). The DA* 60-250 at f4 is very good, there aren't too many lenses that I'm happy to use at maximum aperture - but this one I am

I don't know how the weight of the Tamron compares to the Pentax 80-200, but the DA* 60-250 feels lighter and generally well balanced (it's a bit unwieldy at maximum extension).

I can't comment on the Sigma 120-400, but the range is very different and you probably need to do a bit of "playing" in a camera store before deciding to go for the extra length. Your decision will depend very much on your main purpose for the lens - Aircraft, birding and wildlife may well be better suited to the sigma, but as a good, high quality, general purpose long zoom I don't think you'll go far wrong with the Pentax

Tamron 70-200 at 2.8 is a splendid lens and extra stop will give you better speed & stability in holding large lens compared to 60-250mm. Also, difference between 200 & 250mm is not much IMO and it's easy to realize when you view it side-by-side.

i have the da 60-250, da 200 and da 300 and had a 70-200 2.8 sigma....i use the 300 the most...the 60-250 when i need flexible range and the 200 only when i'm wanting something shorter which isn't very often...the 70-200 just wasn't getting any usuage so i sold it...depending on what you're looking for i would get the 300 or 60-250

sigma 100-300

I came across a MINT sigma 100-300 f4 with sigma 1.4x tc and couldn't pass it up. The IQ is everything everybody writes about. Love the lens.... I already had the DA 50-135 and had to try the 70-200 tammy. I love them all for different reasons....

Nominal zoom focal lengths only match real world results at infinity focus. I once tested the 60-250 against the DA* 200. At around 6 meters, the 60-250 at full zoom was effectively the same as the 200, and at closer distances the 200 had greater reach. So if the extra reach is important to you at closer distances (e.g., bird photography), keep this in mind as you compare lenses.

I found the same as Jeff. The extra reach of the DA*60-250 is only apparent near infinity focus. At closer distances my Sigma 70-200 gave similar or better reach, and up really close the Sigma thrashed the DA*.

At f/4.0 IQ is excellent for both, but you get an extra stop with the Siggie if you need it. The lack of internal zoom on the Pentax bugged me; at 250mm it becomes a very long lens indeed.
