Question About D60 Focal Length

Sun Oct 20, 2002 1:18 am

I was looking at these shots by Colin K. Work:

He was shooting a 300mm lense, with a 2x conveter (= 600 total) and add on the D60 frame multiplier of 1.6 and that gives us 960mm?????

Insane!

I cant believe how clear these photos are. How far away was he?

I guess I can answer that  Smile - first shot was, I guess at a distance of 500 meters (maybe a bit more) ... actually the EXIF file off the camera says it was shot at 10.8 meters ! I guess this is because I was in manual focus mode.

2nd shot, I'd guess around 50 meters.

Of course its not a "genuine" 960mm - the image is exactly what you'd get with a 600mm on 35mm if you only used the center 60% of the image - before anyone asks, these shots are pretty much full frame.

As to the clarity ... the lens is Canon's 300mm f4 LIS - one of the sharpest lenses I've ever used, coupled to the Canon 2x convertor which takes very little away from the prime lens ... and of course the image stablising is a big help when handholding that combo - it's a nice set up, but no AF on the D60 at an effective f8 aperture.

And thanks for the plug  Smile

Cheers,

Colin

Colin,
just had a look at the B&H website- they have 300MM F4 IS for less than 1200 dollars. sounds really tempting. Is yours IS also or straight up?

With the 1.4 extender should give you f5.6 if I am not mistaken, so AF would be still possible......Joe you gotta buy the 400 f2.8 then you can mount a 2x extender and still shoot with the AF. I am speaking from experience  Big grin

Vasco, i spend like stupid on my gear but 400 f2.8 is just out of the question my friend  Big grin -thats one huge reason i bought the D60 -for the 1.6X mag so i dont need the 400 F2.8 -even now with just a measely 70-200 and 2x converter im getting slammin results- at 640mm. D60 is the answer to all my prayers for big lens all these years. I am considering the 300mm F4 primarily because with IS and less than 1200- sounds like a deal!

Joe - I have the IS version and can recommend it. Yes, you retain AF with a 1.4 convertor, however, AF performance is slower on ALL Canon bodies with Canon lenses when using a convertor - Canon actually pass this off as a feature - something to do with "ensuring precision of focus". When I use the 1.4, I shoot in MF mode anyway.

The good news is that the 300 f4 has to have one of the most delightful focusing mechanisms I've ever used - and I've used a good range of Canon's top manual focus lenses. If all lenses were like this, you'd wonder why they bothered inventing AF in the first place.

Go for it - coupled with the convertors, its a very versatile package at a very managable size and weight ... and in case your interest ever strays from aircraft, the macro capabilities with the 2x convertor attached are nothing less than phenomenal .

Oh, yes, Mr Canon, if you're reading this, cheques or cash equally welcome  Smile

Colin,
my interest in manual focus is slim to none unless really warranted- but besides that, sounds like a good deal- im gonna do some hard thinking about this- given that i have my 70-200 with converters now and i do ok with it. Gonna need a few days thought. And dont you worry about the canon man, he already has a crapload of my money too!

Joe - I will say that if I had first purchased a 100-400 and a 70-200, I doubt I would ever have bothered buying the 300. As it happens, I started with a 70-200 and got the 300 and convertors for extra reach - the 100-400 was a lucky 2nd hand find at a later date, hence the overkill!

But although the 100-400 is my most used lens, and probably will continue to be until I get a 2nd SLR body, simply because its so flexible, the 300 is my favorite for quality and sheer pleasure of use.

Cheers,

Colin

Colin, basically theres no burning need for a 300 for me i would say given the thinking i've done and hearing what you have said. right?

Can't answer that one Joe - if you need to shoot at 600mm this is probably the most cost effective way to get there without sacrificing quality ... if that's not a big concern for you, then I guess not - the 70-200 with convertors gives you plenty of scope and flexibility up to 400mm.

Now, it is not a patch on Colin's D60 960mm shots for many reasons but that is also an effective 960mm shot. Was on a D30 not a D60 and also 2 other things, lens was 'bog-standard' 75-300mm and 2x converter was not a Canon one.

I think it was shot from the same location as Colin's shots...car park Colin?

That was at full effective 960mm same equipment as above. Quality is not too good with my equipment as Colin's but I do like having the option of such a large focal length.

Ben - yes the carpark - I noticed that shot immediately ... you obviously ignored the "keep off" signs I've had errected on my patch  Smile
I must say that the combination of zoom and generic convertor works better than I would have expected - lacking a little in contrast and definition compared to the Canon prime & convertor, but certainly good results.

Actually, in terms of absolute image quality, I think the D30 is a little better than the D60 - ever so slightly smoother and a little less noise, probably down to the sensor having lesser pixel density - I believe Canon have returned to this density with the 1Ds.
