p.1 #1 · p.1 #1 · Original Canon 300mm 2.8 Non IS.....Same IQ as the IS version??


Can anyone confirm/deny if the Non IS version is the same optically as the IS version?? (version I)..

If they differ in IQ, how so?

Reason I ask....I have the VII. Never use the IS.....always sports high SS....Wondering if I could obtain 99% of IQ with the Non IS version......

Thanks.

I guess with 300 f/2.8 non-IS you could get close to 90% or so of 300 f.2.8 IS MkI IQ.
However, if the 300 f/2.8 non-IS fails on you, you are looking at 0 % IQ probably for good.
Also, need to remember that the IS version has a much faster AF drive than the non-IS lens.

My first non-IS 300/2.8 that I sold almost 10 years ago was sharp and fast.

Lens can go out of alignment after some time. I recently bought the non-IS recently which was not sharp and exhibits purple fringing. I was glad the seller took it back, but I had to pay for shipping both ways. That was an expensive ($150) one day rental

That sounds better to me. The MkI and MkII (the IS versions) are relatively close performance-wise .......in the case of my lens copies it was very close. The major difference between those two happens when they are coupled with 2xTC MkIII. The MkII 600mm combo's AF is quite a bit more responsive and probably has a bit better IQ then the 600mm combo based on 300 f/2.8 IS MkI..

Another gloom and doom thread, if Canon doesn't service it, it retains only scrap value.

Yes, in principle the non-IS version can be repaired by a few skilled Canon lens/camera service shops (independents), but not Canon themselves, if they happen to have the right parts required, or perhaps no parts would be required for your repair if you are really lucky.
As far as we can tell, those parts are not being made nor supplied any longer, but there are a few perhaps available on eBay. Some independent shops such as KEH might have a few defective lenses that they have been scavenging for healthy parts.

My own experience, as well as what I hear from others, is that if an old lens such as 300 f/2.8 non-IS or 200 f/1.8, or 500 f/4.5L, fails or breaks, that is a very difficult problem to remedy today.

not quite, but very close on avg, so better than 99% of other lenses, it weighs a bit more

All this doom and gloom will be about the VI IS lenses no longer serviced in a couple years. And people will post they don't have much value any more.

I suspect there is a difference simply because of the glass setup, the older non-IS has 8 groups/10 elements while the IS version has 13 groups/17 elements. I personally own the older non-IS which I paid 50% of what a used v1 IS would have cost me and I love it to bits but I'm very aware of the ticking clock. I have done a very quick comparison to a friend's IS v1 and found no visible difference at 300mm and f/2.8, but my non-IS doesn't do so good with a 2x III extender while the IS v1 holds up rather nicely. My non-IS sings with a 1.4x II though. I also had a feeling the IS v1 had a tiny, tiny dash less of CA than my non-IS, but it was too close to tell for sure - the non-IS rocks the lack of CA department despite it's old age.

Here's a frame from my non-IS at 300mm and at f/2.8:

I'm the lucky owner of Petkal's 300 2.8 v1 IS. It is truly exceptional, and I quite enjoy it. A trade for a V2?...I probably can't afford it, but I'm listening

Bob, I simply loved that lens of yours. I think I've had 3 brand new copies over the years, and started with the non-IS version, but that last one was the nicest copy of them all.
I still believe that 300 f/2.8 IS MkI is the best lens per $ (i.e., cost effective) of the whole 300 f/2.8 family.

Peter, I'm quite happy with it, but also use it frequently with a 2x, so improvements in IQ @600 are intriguing.

Bob, the MkII at 600mm might be a bit sharper, but that is like splitting hairs. The only noteworthy difference IMO is the AF responsiveness at 600mm: that is where 300 MkII + 2xTC III shows a marked improvement over 300 MkI + 2xTC III..

Peter, thanks for clarifying. I haven't had issue w focus acquisition speed, so I'll stay put for the moment. Best!
