New lens

Hello,

I have Canon Digital SLR and two lenses
The one with biggest Zoom 75-300

I have friend now in Japan, and he said there are cheap cheap 2nd hand lenses there, if I had the opportunity for new lens, I would go to one with bigger zoom, so I can take nice pictures of people and animals from greater distance.

What is recommended if at all?

Re: New lens

Although I'm a Nikon man, I've always been impressed by shots taken with the Canon EF 100-400mm f4.5/5.6L USM IS lens.

Re: New lens

Well you can look at the Bigma at 50-500mm, but don't expect it to compete with the previous Canon I mnetioned in terms of quality. You'll also need a tripod for most shots at full zoom, unless in very bright conditions & a strong arm

Prices & weight/size will increase rapidly if you want to go any bigger with a Zoom.

Any Canon boys recommend anything else ?

Re: New lens

Tamron do a Tamron AF 200-500mm f/5-6.3 Di LD IF SP (which has the 'SP' bit, the important bit on any Tamron lens name) but other than that your looking at Canon's big prime lenses, and "cheap" with them is a very relative term

If you combine the 100-400 with one of the teleconverters (1.4x is optically better than the 2x one) then you would have a big increase in range. Canon, Tamron and Kenko make them, but they won't work with all lenses, so make sure before you buy (and the 2x one will probably stop your AF working)

Re: New lens

So you convinced me not to buy remotely in Japan, as I need to test it by myself on my camera.

I will look for the lens here in Hong Kong, i am sure there are second hand equipment here as well.

The problem is once you start looking for anything over 400mm you start moving into big-bucks territory with the previously mentioned Sigma 50-500mm "Bigma" or Tamron 200-500mm being the only real cheapish lenses available in that range, I say this without knowing your budjet so I could be wrong here.

You will definately loose autofocus using the 2x coverter with the 100-400, and unless you have a full-frame sensor camera (e.g. 1D mkII, 1Ds mkII) you will most likely loose autofocus aswell with the 1.4x when used with the 100-400. I believe a few 100-400 owners have retained autofocus using one of the Kenko 1.4x converters, but it seems to be pot luck as to wheather it works, with most saying it dosn't.

Re: New lens

Thanks for all the answer, but can someone explain more about teleconverters.

I have similar rings I add between the lens and the body for Macro photography, but I did not know I can achieve the opposite, any downside? is it expensive? Advices? Maybe it will be sufficient without buying new lens.

Re: New lens

Tele-converters mostly come in two sizes rs, 1.4x and 2x with each doineg exactly what they say: multiplying the focal length by their respective numbers. The downside is that you lose 1 stop on the 1.4x and 2 stops on the 2x.

I have the 100-400mm IS L series Canon lens Dave mentioned and sorry, you are very wrong to say you won't get much difference. The quality of the picture is vastly superior to the 75-300mm USM lens that I think is what you have. Ok, some will argue, so it jolly well should be, after all you are talking about a lens that costs 5 times the price! I would entirely agree but that doesn't negate the fact this is one heck of a lens we are talking about.

This also has the image stabilisation that your lens hasn't got which in itself can give you up to 3 stops of better hand-holding potential.

Back to the TCs, let me apply it to my Canon 300mm IS L series f4 lens, one of the best telephoto lenses out there but a prime, not a zoom. If I add the 1.4x TC to it, I get an increase to 420mm (excluding the 1.6x factor because of the sensor size). However, my maximum aperture will drop to f5.6. This still allows me to use autofocus as that is the limit.

If I add my 2x TC (I have both) then the lens becomes a 600mm but I lose 2 stops so now the widest aperture is f8 AND I lose autofocus. Is loss of autofocus a problem? No, not at all. You see, if I am using that lens, I am obviously doing so because the subject is a fair distance away. Therefore all I have to do is focus to the infinite mark and I can be sure it is in focus anyway.

I would just add though that the Canon TCs are both L series quality optics which means you are still maintaining the quality. I wouldn't dream of using a Kenco TC on an L series lens, that would go against the whole point of paying for L series quality in the first place! Admittedly, that does mean paying a fair bit more for the Canon TC, around 190 street price, a touch less on Ebay. As mentioned, the Canon TCs only work on certain cameras so you can't just add it to any lens and get double the focal length.

If I were you and you can get the right price (surely in Hong Kong you have the best prices available on your doorstep!) I would definitely buy the Canon 100-400mm L series and if you really need more distance, buy the 1.4x TC to go with it. You have bright light over there so the loss of one stop won't be a big issue for most of the time. With this lens, you will get stunning quality that you just won't get with anything else other than perhaps the prime 400 or 500mm L series but that really will cost you an arm, a leg and possibly both kidneys as well!

Cheers,
Rob

Re: New lens

I could do with arm and leg, but kidneys? No way.

I am just armature and enjoy playing with my camera, so will live with limitations imposed by any solution, but I will probably not buy an expensive lens (there are limits to what my wife will permit me, and she has the money....).

So if I keep my 75-300, will the TC increase my zoom in meaningful way? 1.4? 2?

I read a bit on the web, still people are not convinced it will have good impact, but all I was looking for is ability to take pictures of people from greater distance than the 75-300 will permit me. And I guess I can get fare price where I live.

Re: New lens

The TC will magnify any imperfections in the lens and is really not going to provide great results with the 75-300, it's going to be F8 which is definitely limiting over here with our grey skys.

The Canon TC's won't fit on this lens, there are two models of Kenko the MC7 (which is OK) and the Pro 300 which is a fair bit better.

It also gives you image stabilisation, fantastic build quality and superb optics.

The Kenco 300 Pro is generally considered optically to be pretty much as good as the canon version (the 1.4 especially), certainly as far as the eye can see anyway. The Canon "may" have a slight advantage if you're looking at resolution charts but the Kenco is the better buy in my opinion. The biggest benefit of the Canon TC's IMO is the weatherproofing but if you're not using it on a 1 series with an appropriate lens it doesn't really matter anyway.

Very true, sorry for the confusion... To clarify, all the 1 series camera's can autofucus with apertures as small as f/8 (Models include; EOS 1D, 1Ds, 1DMkII, 1DMkIIN, 1Ds MkII, and film cameras EOS 1 and EOS 3).

Re: New lens

If you are using a TC with an L series lens, you will definitely lose quality with anything other than the Canon TC as these are optically matched for use with the L series lenses. That doesn't mean the Kenco is a bad TC, it just isn't optically matched to this set of lenses. Yes we're talking about the sharpest areas of detail and to some eyes little difference will be seen but if you are doing detailed work or major enlargements, the differences are definitely there. I do a lot of printing at 18" x 12" and so the difference would be noticeable.

Just to point out though, the Canon TCs are designed for a specific group of lenses, not for all Canon lenses. You can't just take a Canon 75-300mm lens and double it with a Canon 2x TC anyway so a non-Canon TC would be required. Why? Because as I said before, the optics on these TCs are L series quality. There is no more point putting a non L series lens on one than there is putting an L series on a cheaper non-Canon TC.

The design is such that other lenses do not fit on because of the lack of depth of the rear element.

I have to say, if you really want quality, the best way is to get a 300mm prime lens and then put a TC on it. Expensive yes but the quality will be superb.

Cheers,
Rob

Re: New lens

Even Canon don't say their TC's are matched to their lenses optically. They do say they are designed to give optimal performance but they would do wouldn't they

It's similar to a number of third party lenses being sharper than the canon L equivalents, Canon would hardly be expected to promote that.

I am sorry Rob but in this case I firmly believe that you are mistaken and I fully agree with Dod.

The Kenko 1.4x Pro 300 converter has nothing but superb optics and unless you are using charts and scientific tests to tell the difference then you will not see any at all either on prints (at any size) or on screen using the naked eye.

When I bought mine I did a massive amount of research on converters and armed with that knowledge I purchased the Kenko. It works with all my lenses (not just specific Canon ones). Returns stunning results and behaves consistently when in use.

Sure the Canon TC is better made with weather sealing but that only works with weather sealed body/lens combination and the extra cost to me for that alone made the Kenko a far better value for money buy.

Re: New lens

Like I said Steve, if you want a TC for all your lenses, the Canon is NOT the one to go for. It is only the one to go for if you are using it with a specific set of L series lenses. So in your case I would have gone for the Kenco as well! Not much point in a TC that doesn't fit your lens.

In my case I have the Canon 100-400mm L series as well as the 300mm f4 L series and the combination with Canon TC of that latter lens is pretty much unbeatable.

I don't have any real use for a TC to go with other lenses as they are all shorter so I have the longer lens to cover the range they would be if doubled. Anyway, we have the TCs we want and are getting good results, it is just about helping rsegoly and he has already said he is not ready to go and spend out on L series and things so perhaps this is irrelevant to him anyway.

Just as a matter of interest Steve, and this is not quite on topic but, do you use your Canon 17-40mm as a standard lens on camera or your Tamron 28-75? I assume the latter due to its range but how do you find it? A friend was talking about this lens for himself for Christmas but I've never seen it for real, handled it etc. Good buy for someone who wants to keep it on the camera as standard lens? On a 20D this is.

Cheers,
Rob
