When buying a Pentax K5, should it be equipped with a 1.2 header or an 18-135 water dog?

The recommendation is still 18-135WR.

Because it is very important to complete the focal length. With the A50, you will have to use such a narrow angle of view to take pictures in the future. There are very few subjects. This is one of them. Also, the K5 is a waterproof camera, so bring it with you. With a waterproof head, you can use it in rainy days. It should be noted that rainy days are also a good shooting subject. However, due to the construction of the body, other brands of mid-range phones cannot be taken out to take pictures. Finally, the A50 can only focus manually. What do you think? When you use manual focus on all the subjects, it’s enough for you.

A50/1.2 both have PK ports, can be installed on K5 and support automatic light metering. This head has been discontinued for a long time, and second-hand ones in good condition cost more than ￥4,200.

In fact, if you are not obsessed with the large aperture of 1.2 (the aperture is so large, manual focus must have good eyesight, otherwise the image will be blurry), for this price, you can consider the Princess (the best in the world) for a little more money. The lens with the sharpest aperture imaging), ★55. Of course, if the price is really beyond expectations, you can also go down to FA50 or DA40. These are great portrait heads.

If you want both lenses, it is recommended to buy 135 sets of K5 and then shoot A50/1.2 yourself

￥12800 + ￥4200 = ￥17000

The hoods are all included.

One piece of UV is only ￥200

The camera bag is of slightly better quality for ￥300

The card is even a Toshiba white card (C10) 8G, which is ￥150

Add a spare battery, an air-blown lens pen, and a tripod, and the total is just over ￥18,000!

Supplement:

K-heads are all classics - this is the evaluation of K-heads by Pentax users.

The K head is Pentax’s first generation film lens. It is made better than the later ones and is made of all metal.

But compared to the A head, the K head cannot support aperture linkage, which means it can only manually meter the light.

If you have to manually meter the light and focus manually, it will be a bit fiddly to use - at least if you are just getting started, it will take a long time to take a photo...

K50/ 1.2 is the same as A50/1.2. There are no new products, only second-hand products. Second-hand ones in good condition cost about RMB 2,500.
