Tamron Adaptall-2 SP 350mm f/5.6 (mirror) (06B)
supersize


Description:
The shorter focal length and faster mirror has acquired something of a premium status for digital crop factor cameras.

focal length = 350 mm
aperture = f/5.6 fixed. Note that there is a significant difference between f stop and t-stop with mirror lenses.
angle of view = 7.3
Optical Construction (Groups / Elements) =4 / 7
Min. Focus from Film Plane = 43.3" (1.1m)
Diameter = 3.4" (86mm)
Weight = 20.4 oz. (577g)
Lens Hood = Screw-in type #19FH, reversible.

Accepts SP 2X tele-converter #01F and SP 1.4X tele-converter #140F. Note: TC's are reviewed in miscellaneous lenses - TC's.

The 350mm has a different mechanical construction to the 500mm 55B. On this lens the tripod mount is fixed with screws and the lens can be rotated from landscape to portrait by pressing a locking tab on the base of the lens. Holding the lens on the camera, the main body of the lens rotates clockwise (mount end perspective), the TM ending on the left side.
There is also a small screw that locks a sleeve on the mount, this is specifically for nikkomat camera compatibility.

Lens Review Date: May 8, 2020 I can recommend this lens: Yes | Price: $460.00 | Rating: 9 

 
Pros: Short, well built, Sharp, Close Focus
Cons: Mirror Lens typical issues
Sharpness: 9    Aberrations: 10    Bokeh: 6    Handling: 9    Value: 9    Camera Used: Olympus Pen-F, Fuji X-T3   

This lens is very similar to the Tamron 500/8.0 MR-SP. Same diameter. Superbly built. Very short minimum focus distance.
The sharpness is totally amazing, above average for a mirror lens, and is nearly as good in the corners as in the center.

It has the typical plus and minus of mirror lenses.

Plus:
- No chromatic aberration
- Very short
- Very light

Minus:
- 'Donuts' bokeh
- Difficult to focus accurately
- Large diameter
- No diaphragm - it is f/5.6 and nothing else
- Low contrast, but it does better than other mirror lenses, and that's very easy to correct digitally later
- The real aperture is more like F/6.8, there is a loss due to the mirrors

Lens Review Date: February 14, 2015 I can recommend this lens: Yes | Price: None indicated | Rating: 10 

 
Pros: Excellent Mirror Lens, Compact & fast
Cons: short focal length for a mirror lens
Sharpness: 8    Aberrations: 10    Bokeh: 6    Handling: 9    Value: 9   

I rate this lens a 10 for a mirror lens and would rate it at 6 to 7 against regular lenses. This is the best mirror lens I have seen. I realize that isn't saying much. It also is f5.6. The only real downside is the fact it is 350mm which is a short FL for a mirror lens.

Pros: Light, reasonably sharp
Cons: Difficult to focus - or rather, DoF is very small
Sharpness: 8    Aberrations: 9    Bokeh: 5    Handling: 5    Value: 8   

In short: It gives you nice contrasty sharp pictures - but its very limited Depth of Focus makes rehearsing use a necessity.....

A lot better on my K-5 than on my K1000, as I now have a sensitivity that means I can use suitably fast shutter times.

Highly recommended - its only faults are general to all mirror lenses. The Donut Bokeh, the lack of an aperture and hence lack of DoF.

Lens Review Date: March 30, 2012 I can recommend this lens: Yes | Price: $300.00 | Rating: 9 

 
Pros: very sharp,easy to hold
Cons: sometimes unpleasant broken
Sharpness: 9    Aberrations: 9    Bokeh: 5    Handling: 9    Value: 9   

Bought this lens used many years ago,mainly for astrophotography but is a pleasure to use any time and very compact to carry.Used first on my minolta but Extremely happy with it on my K10. The focus can be a chore to achive but is very rewarding though I have had nothing else to compare it with.I would recommend it but careful what you pay for it...I have seem them as high as 800.00 on ebay.
edit: I felt I had to explain why I rated this so high while others may have been more bias.For my needs this lens is so fun to wander around with and a workhorse piggy backing on my telescope.

Pros: Lightweight, compact, good color rendition, no distortions or abberations
Cons: fixed aperture, difficult to focus
Sharpness: 9    Aberrations: 10    Bokeh: 4    Handling: 5    Value: 7   

Note: I bought this from new in 1982, and that's the price shown.

This lens is rather difficult to rate from a general user's point of view. The focussing IS a tedious business - although practise helps a good deal. It isn't really for "action" because one has to turn the focus ring a lot - and then jut a tiny movement of the ring will make an awful lot of a difference. I should say that it IS very sharp, but only when focussed absolutely correctly.

A catadioptric lens is a special piece of equipment; I do recommend this lens, but only for those that will know, what to use it for and why.

Of the many things that I like about this lens I should mention first and foremost its excellent color rendition and lack of any distortions/abberations and next its ease of portability. It is only 8 centimeters long and easily fits into a small shoulder bag as a second lens. (I also have the SP 300mm f/5.6 Model 54B and that lens is much less portable for an easy stroll).

In 1982, I primarily bought my lens for astrophotography and I have never regretted my purchase. I also have the Tamron Teleview Eyepiece from that time and thus, also a nice spottingscope providing 17.5 X 62.5 and 35 X 62.5 with the SP 01F teleconverter.

In the digital age, I have found new uses for it - also thanks to Pentax in-camera shake reduction.

Pros: sharp for a mirror,light for a 350mm
Cons: bit slow, dim viewfinder makes focussing difficult

Picked this lens up cheaply many years ago.Have a 500 f/8 and 300 f/4, so this focal length a bit redundant. Lens very slow compared to the bright 300 f/4, compactness advantage lost by more difficult focus. Opically, not as sharp as 300 f/4 glass, but considerably sharper than 500 f/8 Tamron. As mirror lenses go, it is very sharp and light /compact. Weight is not too much of an issue for me, so the 300 f/4 Pentax K rules (Tamron 300 f/2.8 weight is an issue though.)

Pros: lightweight; small size compared to more conventional lenses
Cons:

This is a well-built, rugged lens.

It came with the standard metal lens hood which reverses for storage, and also with a tripod mount. However, because of its small size and lighter weight it is far easier to handhold than AF regular lenses of similar focal lengths which makes it convenient when tripods aren't an option, such as ballparks.

On occasion the lens gives the typical mirror-lens donut highlights in the background, but not nearly as often as one might think. Contrast and color are both good.

While I typically use the 500mm Tamron mirror for birds, I use this one for sports and have been very pleased with the results.
