Canon 70-300mm f4-5.6 L series lens with Kenko pro 300AFX Lens

[erroll1906]

Hi everyone I have a canon 70-300mm f4-5.6 L series usm lens,which is one of the lenses that canon tele converters don't fit.Its a beautiful lens but just needed that touch extra reach out to 400mm.The canon tele converters don't fit due to the element protruding out which would damage the element on your lens.I have a canon 5d mark iv camera so was looking for a third party converter that would suit my camera and lens.I took the plunge and bought the kenko teleplus pro 300 AF 1.4X lens.This lens communicates well with the camera and the lens,auto focus is sharp and still crisp.At 420mm its at f8 and I believe because with my quality camera and lens the images are excellent.I was going to sell my lens and buy the Canon EF 70-200 mm F/2.8 IS II USM Lens with the canon x2 tele converter,which would give me the 400mm at f5.6.But that comes at a hell of a price when I already have a 300mm L series lens.Look at the images and see for yourself at 420mm at f8 you can still get great bokeh with good settings on focus points.Was lucky enough to capture my first kingfisher photo that day.Hope this helps if you have been as frustrated as I when the two canon tele converters don't fit this lens and you want that bit extra reach.

At 420mm its at f8 and I believe because with my quality camera and lens the images are excellent.I was going to sell my lens and buy the Canon EF 70-200 mm F/2.8 IS II USM Lens with the canon x2 tele converter,which would give me the 400mm at f5.6.But that comes at a hell of a price when I already have a 300mm L series lens.

Sorry, but I have to be blunt. None of the photos above is particularly sharp. The second one is misfocused (check the bark) and there's probably some motion blur. The first (third) is just mushy if cropped.

Check the exif data. Sigma 150-600 + Kenko PRO 300 DGX 1.4x.

Nice pictures.Thanks for your comments and yes could be better,my shutter speed was to low.That was my first time out using the tele converter,although not pin sharp but not too bad really.

Hey,

I was thinking the pics are not sharp! though you have high ISO, have you tried few more? I am interested to have a look as I'm also planning to get 70-200 with extension tube, good to see images with your 70-300 L lens.

By the way, your Profile gear is showing Canon EF 24-70mm f/2.8L USM read you mentioned in another thread(Re: Panamoz shop) you had Canon EF 24-70mm f/2.8L ii USM new lens have you changed yours

Thanks,

Vamsi

Waste of time and money and you'll always be frustrated. Buy a 100-400 II which you can still use with a 1.4x iii TC. Alternatively, look at the Sigma version or their 150-600 (though I could never get them to AF accurately). There is no cheap substitute for good, long glass and the 100-400 is really the most resonable entry level apart from the ancient 400 L 5.6. From there you are entering the big boys league with many thousands of $.

Kenko DGX 300 Pro 1.4x is as sharp or sharper than Canon 1.4x III TC. The main problem is communication with a body. My Kenko works decently with 7D and Sigma 150-600, it doesn't work with 80D. There's an error message at the moment you go beyond f/6.3(f9.0).

Sigma 50-100/1.8 doesnt' work at all with 80D and Kenko extender, but it works perfectly with 7D. Same goes for all the other lenses.

Canon's 200/2.8LII with Kenko works perfectly on 80D.

Kenko and all third party producers have a lot of problems with every new Canon's release. I think it's intentional on Canon's part.

While you may like the Kenko TC, the AF on the Canon III TC's is optimized to work with the version II lenses. According to Canon:

Version III: Extender EF 1.4x III and Extender EF 2x III (introduced December 2010)

• Both 1.4x and 2x are optically redesigned, with superior image quality versus the previous generation extenders, especially with the 2x III version
• New and brighter white finish that matches the new whiter color of latest EF super-tele lenses
• Enhanced strength and durability: now seven screws (versus four on previous models) on the body’s side of extender’s lens mount; stronger lens lock pin design and extender stopper pin on lens mount
• Fluorine coating on front and rear extender elements are more resistant to smears/dust/dirt and far easier to clean
• Weather-resistant gasketing applied to release switch on extender, in addition to front/rear mounts
• Updated CPU and electronics to provide greater AF accuracy when used with most recent EF “version II” IS-series super telephoto lenses; also relays specific extender information (serial number, etc.) to be recorded as shooting data by latest EOS cameras
• Important: Version III EF Extenders are not compatible with EOS 35mm film SLRs, except for the EOS-1v camera. These extenders will work with all EOS DSLRs
• Version III EF Extenders are specifically recommended when adding an accessory tele-extender to the EF 200–400mm f/4L IS USM Extender 1.4x lens

For seven years I've been photographing birds with the 70-300 L. Never used a tele converter.

Why? This lens is made for cropping. However, it comes at a price, you have to use fast shutter-speeds. Take twice the focal length and calculate what you need to add when cropping.

As a rule of thumb, perched birds need at least 1/800, when flying 1/1600.

The lens is great but nor forgiving. Stabilize it as good as possible, practice with the IS settings etc. For instance, on my 70-300 L setting 1 works better with flying birds than setting 2.

After I bought the 100-400 II there was no reason to sell the 70-300 L. It is the most compact L telezoom available, suitable for shooting wildlife and compact/light enough when hiking in difficult terrain.

Hi Vamsi no mate its the mark ii lens I have

[erroll1906]

Hi good comments,and thanks for the tips on the lens with the shutter speeds

Erroll

 

[Southernapachi]

70-300 way sharper than the 100-400 II. Also smaller even with tele. At worst use a good sharpening AI. Far from a waste

Your choice of shutter speeds aren't too low, they are way to low. This is a first mistake with newbies to very long lenses. And I don't know if your lens has IS but you can turn it off when using the lens at the long end with very fast shutter speeds. You should be shooting from 1/1000th to almost 1/2500th of a second.

Google minimum shutter speeds using long telephoto lenses.
