EC 20-2x
 
Hi there, is there an EC20-2x for hire and what effect does it have on a lens, regards John

Hi John
There is an EC-20 for hire, I used it back at the beginning of May (superb service by the way) with my 50-200 SWD. It does give impressive reach, but I struggled to get any sharp images with it. Having said that I was using it for BIF (Red Kites) and I'm sure that a less agile subject matter, less wind, better lighting and more skilled user could have given much better results.
I have the EC-14 which I like using with the 50-200 and while I had the EC-20 I experimented by putting them both on the lens! The camera wasn't too keen but I could manually focus and take shots of a Kite in a tree using the tripod; the trouble was the wind - everything was oscillating :D
You don't say what you want to use it for, but I recommend hiring it to have a play and take advantage of the excellent service provided here.

Hi Ian, does this attachment effectively double the range of the 50-200, which I'm going to use, or is that being to optomistic, regards

That's exactly what it does at the cost of a two f-stop loss. That means that it won't be the fastest lens in poor light conditions.

Hire one of the f2 long lenses to see the ec20 in its best light. I have never been really happy using mine with my 50-200.

Re: EC 20-2x
 
I have been slightly disappointed with my EC20 mainly becasue of the loss of two F-stops., the E30 plus EC14 and 50-200 mm is probably a better combinationthan E30 +EC20 and 50-200 mm combo.
Having said that I think it is quite useful, being reasonably sharp in the center at F:7,1 , auto-focus works great and also it is a reasonably small addition in bulk and weight.

Some examples (all handheld) :

Lion at the Zoo on a cloudy day, distance approx 20 meters 100 % crop.

EXCIF : F:7.1 1/200S Focal lenght 294 ISO 800 NR off IS1

Owl chick in the shadows, distance approx 12 meters heavily cropped:
http://i296.photobucket.com/albums/m...le/01Small.jpg

F:7.1 1/160 S Focal Length 400 mm ISO 800 NR off IS1 EV + 0,3

Both looks great on A4 print (with a relatively cheap HP6510 Ink-jet)

By accident I tried the 35-100 mm F2:0and EC20 combo and that was great, slightly better than the 50-200 mm F:2.8

I personally believe that the EC20 deserves HG and SHG glasses and an E-5 camera for best results.

The EC-20 does double the focal lengths from 50-200 to 100-400, but at the cost of two stops of light, so maximum aperture is reduced to f/5.6-f/7. The EC-20 does lose a little more sharpness than the 1.4x EC-14, but it's not unusable with the 50-200. It does shine, especially, with the 150mm f/2, 35-100 f/2 and the 90-250 and 300mm biggies (both f/2.8). The EC-14 turns a 50-200 into a 70-280 f/4-f/5.

In case you should want to buy one

If birding is your thing in reasonable light the EC-20 and 50-200 work very well I my experience..

All almost wide open (f/7.1) @ 400mm with the E-5

Edit, here's one in not so good light, hand held with the E-M5

Magnificent moon shot ! *chr

Well done

Amazing, all of them! I could never get that kind of quality with the EC20, maybe if I stop down more itr would be sharper?

I obviously need the e5 to use with my ec
20 and 50-200 combo!

The last image was with the E-M5 so I think it's more a case of matching characteristics of a particular 50-200 to the EC-20.
There are bound to be variations due to manufacturing tolerances, assembly and set-up, so perhaps some 'pair' better than others :)

There is a limit to the amount of stopping down you can actually do with this combo. I have determined that f9 is the optimum aperture. Any smaller then your shutter speeds and/or ISO are going to be compromised

Re: EC 20-2x
 
I am surprised with the sharpness in the pictures shared by Huw, these have better detail rendering than the results I have obtained with my 50-200 SWD + EC20. Did you use MF, Huw?

Regarding Cathrine's comment: F7.1 on this combo should be wide open if I got the maths right.
