With the new 70-300 L IS coming out, with what appears to be a list price of $1599, it appears to put a bit of a pressure on the older 70-200 f/4 L lens line up. Moreover, in order for the 70-200 to reach out to ~300, you need a 1.4 tele extender, which increases cost over that 70-300 and sacrifices image quality.

Indeed, after reviewing the MTF charts of the Canon lens line up, it would appear that this new 70-300 f/4-5.6 L IS appears on the tele end to rival canon's own 300mm f//4 prime (at least on paper). And be in equivalent territory of the 70-200 f/4 at 70mm.

It seems that the only good reason now to get a 70-200 f/4 is if you absolutely need f/4 @200mm versus the 70-300 being f/5 @ 200mm.

This new 70-300 L IS <strike>also is about a pound lighter than the</strike> 70-200 L IS f/4, while still retaining weather sealing.

Here are the MTFs for comparison (I've scaled them since canon odd-ball sized each chart). Also, note that the blue lines are each lens' performance at f/8.

The 70-200 f/4 still has one big advantage - price! Even for the IS version.

The 70-300L sets a new price record in that range, so it really does need to be that good to justify it.

I think you mean the 2.8 version here. The f4 IS version is .6# lighter than the 70-300.

For me the 70-300 is insane expensive for what you get. You could nearly buy 4 of the Tamron 70-300 USD VC for the same price. If I am going to spend $1500, I'll look around for one the the 70-200/2.8 IS used on craigslist.

It depends on what you want. Comparing an old used lens to a brand new one isn't ever going to balance on value.

Like every other new release, the 70-300L is going to be overpriced. If you look at the 70-200 II for comparison, that's dropped about 30% since it came out earlier this year. Assuming a similar rate of drop, I think the 70-300L will be about price parity with the 100-400L in spring next year.

The closer logical comparison would be a new 70-200 f/4 IS with 1.4x II extender, and that isn't so impressive either in image quality, with more limited zoom range and aperture.

If I didn't already have the 100-400L and looking to buy new soon, the 70-300L would certainly be on the short list.

I don't doubt the Tamron isn't great for the price, but there's one possible deal breaker for Canon owners I haven't managed to confirm or not yet - zoom ring direction as all images I can find on the net are Nikon versions. Tamron's default zoom direction is opposite to Canon's, and it is very annoying having a mix of both! I don't know if Tamron tooled the lens to flip the direction for Canon but they didn't on other lower cost zooms.

In the US the 100-400 with the $110 rebate is $1500 so they are at parity now here. I would expect the 70-300 to be cheaper in a year. If it was the same as the 70-200/4 IS, then I would put it on my radar. You wouldn't mind loosing the 100mm on the 100-400 for better IQ?

I hear you about the Tamron being backwards. It was on my 28-75 and I would expect the same on their 70-300.

whoops, yes, its not lighter. I'll change that...

I think the 70-300 is indeed pricey, but in comparison to the 70-200 L IS, it is a very close race (optical performance wise), because in order to attain the same focal range, you'd also need a tele converter. So basically, you are buying 1 lens plus an extender, or 2 lenses (if you choose to get a dedicated telephoto at 300 mm). Also, the reason I tend to rule out the 100-400 is that it is too telephoto on the wide end, 70mm is really needed sometimes.

Appears that the lens will be retailing for $1599... and available in late November. Although I've read that lens is available now in the Netherlands... anyone know if this is the case?

I saw one sample elsewhere where someone has bought the lens already. In a quick scan of some UK websites, 2 are saying they're in stock with 3 others still on pre-order. Price is clearly higher than 100-400L.

There's a video review on youtube here of the lens:

He essentially voices some of the same concerns others in this thread have raised. For $1600 it doesn't come with a tripod collar! ouch.

He also posted some sample images here:

Digitalrev has just posted a youtube video review of the lens (click on picture), and concludes that at its price point it is up against the 70-200 2.8 non IS version one lens. Hmmm.

Found this very nicely written and detailed review of the 70-300 L IS matching it directly up against the 70-200 f/4 L IS. Wish they had done the corner comparisons. And Wow, the 70-200 +1.4 TC is not bad at all...

http://dancarrphotography.com/blog/2010 ... 0-f4-l-is/

Still, there is no included tripod collar, grrrr.

They provided some flickr full res examples:

Hi capital,

Great find. And good to know that if I ever need a little extra reach then adding an EF 1.4x III to my EF 70-200mm f/4L IS USM will do nicely. 8)

I like this lens and if you need a 70-300mm this is the one to get. But I don't get why canon made it f4-5.6! That is the only thing putting me of buying it. I will still buy the 70-200mm f4 IS.

What do you all think about the Canon 28-300mm f3.5-5.6? Does it have good image quality or is IQ sacraficed for focal range?
