The last double 11 defeated the Appropriate Horse Black Technology 1835 and learned that the Sigma also had a 50-100 1.8 black technology telephoto, and saw that the bright black long plus a constant 1.8 aperture was not resistant to long Grass, but this head hasn't got Pentax yet. However, this shot caused my interest in telephoto, so I began to focus on the forum and posting. Several of my options are Pentax 55-300, Star 50-135, Star 60-250 and Tamron A001. First of all, PASS is a star 60-250, because I am a large aperture dog, the aperture of the head is a constant F4 as 535 and A001, and the price is the most expensive of these heads. Then, taking into account the thickness of the purse, once thought of 55-300, even in the salted fish has been ordered, but the salted fish seller said that the lens has been given away. Then, in the salted fish, I saw a good 535 with a good price, ready to order and the head was taken first. In the end, I think that it is possible to make a full-size picture in the future, so I entered this cheap and affordable Tamron A001.

There is a seal on the left
Followed by recent photos
Yellow coating
The work has been very busy since the camera arrived. These days, there is only time for detailed auditioning. Let's first look at the appearance of the lens.
Compared with 50 dogs, you feel it. It is also a lot longer than s1835, the real black thick.
In this right and wrong place, the A001 has been blurred. But it can also be seen that the work of Sigma is better than that of the Tamron A001.
Next shelf to see if it can be used to sneak shot
After several uses, I found that this head really has a vacuum cleaner effect, did not take a few photos, after the first lens into the gray, as shown, but fortunately I do not have obsessive-compulsive disorder, the first obsessive-compulsive disorder carefully into the ah
Next on a few samples to everyone to see, are JPG straight out no later, body K5IIS
70-point and 200-angle
This dragon head is cheap and has a large aperture. What do you think is more fixed aperture, the original color is better? I don't care. Anyway, I didn't have a large aperture and I didn't have a thick and fixed length. The original factory was not cheap with me. In the end, I want to say whether there is any sister in Xiamen about shooting, otaku never made portraits, would like to pat the young lady
Slide Switches
The Slide Switches is used to switch the circuit by turning the switch handle to turn the circuit on or off. It is different from our other serious switches, for example, Metal Switches, Automotive Switches, LED light Switches, Push Button Switches, Micro Switches, The commonly used varieties of Miniature Slide Switches are single pole double position, single pole three position, double pole double position and bipolar three position. It is generally used for low voltage circuits, featuring flexible slider action, stable and reliable performance. Mainly used in a wide range of instruments, fax machines, audio equipment, medical equipment, beauty equipment, and other electronic products.
The Mini Slide Switches are divided into: low-current slide switches (right), and high-current slide switches (left). Small current slide switches are commonly used in electronic toys, digital communications. High current is generally used in electrical appliances, machinery, etc.
It can divided into 4 types modals, respectively are:
1. High-current sealed switch
Its rated current is as high as 5A, and it is sealed with epoxy resin. It is a large current sealed switch. It has a variety of terminal forms, contact materials are silver, gold, switching functions. Therefore, there are many types of subdivisions. Widely used in electrical appliances and machinery
2. Single sided snap-on surface mount type slide switch
The actuator is operated on the side and the pins are patch-type, so it is a unilateral spring-back surface mount type slide switch. Widely used in communications, digital audio and video
3.4P3T in-line slide switch
The contact form is 4P3T and the pin is in-line. It is 4P3T in-line slide switch. 4P3T determines that it has 8 pairs of pins. At the same time, there are two pairs of brackets that support, fix, and ground. Widely used in building automation, electronic products
4.Long actuator jacking type slide switch
Actuator 12mm, and located at the top of the switch, it is a long actuator jacking type slide switch. Widely used in digital audio and video, various instruments / instrumentation equipment
