Recommendations

This is a very practical way to get serious pro portrait firepower at a fire-sale price.

Everyone needs a 300/2.8. Even if you don’t plan to use it, show up with it on your camera and you instantly look like the top pro you are. When you arrive at an event, you may be able to sweet talk your way to the VIP area for free.

There’s no cheaper way to get awesome bokeh and completely soft, lost backgrounds.

For nature and landscape, this is a lot of glass for very little money. It’s fast and sharp.

The only gotcha could be that you never know if it will be fully compatible with your particular model of camera until you try it, if I didn’t already .

If you get one without the included Tokina 112mm front protective filter, I’d use a 112mm B+W MRC 010 UV filter to protect this lens. I don’t know that I’d pay extra for multicoating; the lens isn’t that well coated in the first place and 112mm filters get very expensive very quickly.

Be sure you have a 35.5mm filter in the rear filter holder with your lens. You may be able to use this filter or this one.

These Tokina lenses are always easy to find where I got mine at this link directly to them at eBay; see How to Win at eBay.

This all-content, junk-free website’s biggest source of support is when you use those or any of when you get anything, regardless of the country in which you live. xx does not seal its boxes in any way, so never buy at retail or any other source not on since you’ll have no way of knowing if you’re missing accessories, getting a defective, damaged, returned, store demo or used camera. I use the stores I do because they ship from secure remote warehouses where no one gets to touch your new camera before you do. Buy only from the for the best prices, service, return policies and selection.

Thanks for helping me help you!

Introduction

B&H Photo — Video — Pro Audio

I buy only from . I can’t vouch for below.

The Tokina 300mm f/2.8 AT-X is an ultraspeed ultratelephoto lens from the 1990s.

Today it’s inexpensive and easy to find, built like a tank, and has great optics. It’s an inexpensive alternative to Nikon’s or Canon’s 300mm f/2.8 lenses. It gives far better bokeh and much softer backgrounds for professional portraiture at a fraction of the price of any new 70-200/2.8.

It comes in mounts for Nikon, , Sony A, Minolta MAXXUM and possibly other mounts. I have the Nikon mount.

For Sony E, I’d suggest finding one in Minolta MAXXUM (Sony A) mount and using the Sony LA-EA4 adapter which ought to give fast autofocus and full automation. Since Minolta mounts are hard to find (this was an exotic, expensive pro lens in its day, and pros never shot Minolta), you’ll have an easier time finding one in Canon mount and then using a Canon EOS EF to Sony E mount adapter. Good luck.

Versions

I have the AT-X AF version.

There is an earlier manual-focus only version, which presumably has the same optics.

There is a newer AT-X AF II version.

The newest version is the AT-X PRO version, which I believe also has the same optics, but adds a push-pull clutch to the focus ring to speed-up auto/focus switching. This version speeds that up, but once in manual, I suspect the feel is better in the earlier versions.

Good

● Very sharp.

● Reasonably close focussing: 7.9’/2.4m.

● Fast manual focus; flicks with a fingertip.

● Solid all-metal construction.

● Simple, sturdy technology suggests long service life — there’s nothing to break!

Bad

● As with all third-party lenses, there’s always the potential for incompatibility with some models of camera or lens adapters.

● No instant manual focus override; have to move a switch.

Compatibility

Nikon

This is a traditional screw-focus AF lens, with electronic contacts as well as a traditional AI-s aperture ring for use on old 35mm Nikons.

I tried it, and it works great on my Nikon D810, Nikon D3, F100, FA (uses the low-speed program optimized for landscapes)), F4, N5005, N55 (gives the high-speed program optimum for sports), N75 (gives the high-speed program optimum for sports), D70 (gives the high-speed program optimum for sports), D300, D200, N2020, N70 (gives the high-speed program optimum for sports) and Pronea S (gives the high-speed program optimum for sports).

Auto exposure control works, but focus is manual only, on my F6 and D40.

It works fantastically well on manual-focus cameras like the F2AS, F3, FE and FA as well, since it has real manual-focus and aperture rings that work exactly as they should.

This screw-focus lens will not autofocus with the cheapest D40, D40x, D60, D3000, D3100, D3200, D3300, D5000, D5100, D5200, D5300, D5500 or D5600, but if you focus manually, everything else works great. These cameras have in-finder focus confirmation dots to help you.

I haven’t tried it, but I suspect it should be fine on the D7500 but not have any metering or AF on the D3400.

It works with the Nikon TC14 teleconverter to make it a manual-focus 420mm f/4.

See Nikon Lens Compatibility for details on your camera. Read down the «AF, AF-D (screw)» column for this lens.

Be forewarned that at a third-party lens that there is always the potential for incompatibility.

Canon

I haven’t tried it, but Canon’s EF lenses work on all their EOS cameras, so I’d hope that the Canon version ought to work on all Canon EF EOS cameras.
